->"''This wrench is good for both tightening nuts and bashing skulls.''"
-->-- '''Enormous Wrench Description''', ''Videogame/DungeonsOfDredmor''

Wrenches are tools often associated with TheEngineer and the WrenchWench, using them to build and repair objects, whether by tightening bolts or PercussiveMaintenance. Like other tools used in construction ([[DropTheHammer hammers]], {{nail|Em}}guns, etc.), wrenches [[ImprovisedWeapon can be very effective weapons]].

Very much TruthInTelevision as a good monkey wrench (also known as a pipe wrench) can be made of very sturdy materials, and some can weigh quite a bit on top of that. So, in a pinch, you can very easily break someone's skull wide open if you hit'em hard enough.

Unrelated to SpannerInTheWorks, unless what derails your EvilScheme is [[CrouchingMoronHiddenBadass underestimating the combat potential]] of the WrenchWench. See CrowbarCombatant for another tool used as an effective weapon.

* Mikazuki Augus from ''Anime/MobileSuitGundamIronBloodedOrphans'' adapted a gigantic [[DropTheHammer wrench mace]] for the Gundam Barbatos since the original mace was lost.

The biker mockingly points to the other side of his jaw and suggests J.J. try there. J.J. says "Thanks" and immediately smacks the biker across the face with a spanner.
* ''Film/RumbleInTheBronx'' subverts this with Creator/JackieChan starting out by hitting the GiantMook, [[NoSell to no effect]] – then the TagalongKid passes him a bike helmet, which he whacks the guy's face with, still no effect - then the kid gives him a big wrench. One look at it and the mook caves.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Mekton}}'' has a RunningGag of mecha pilots making stupid design suggestions and getting hit on the head by the resident WrenchWench.

[[folder:Video Games]]
* Cid uses wrenches as weapons in ''VideoGame/FinalFantasyIV''. Hilariously, they're some of the strongest weapons in the game while he's in your party- even better than swords and karate.
* Gremlin Thwackers in ''VideoGame/SpiralKnights''.
* ''Franchise/RatchetAndClank'': Ratchet uses the Omniwrench, which he uses for its actual purpose too.
** Ratchet can also [[PrecisionGuidedBoomerang throw it as a boomerang]] or [[IncendiaryExponent set it on fire]]. Furthermore, ''the entire Lombax species'' seems to favor a wrench as their WeaponOfChoice. Gameplay-wise however the wrench is only good for clearing out GoddamnedBats or sometimes [[CherryTapping killing stronger enemies]] for skill points.
* Adrian Shephard in ''VideoGame/HalfLife1: Opposing Force'' has one. It's stronger then Gordon Freeman's [[CrowbarCombatant crowbar]] but swings slower. He later gets a combat knife which is weaker but swings faster.
* ''VideoGame/TeamFortress2'': the melee weapon of the Engineer. It is used for [[PercussiveMaintenance hastening building, repairing and upgrading]] the Engineer's buildings. Other uses include hurting people - and the wrench is good at it, hitting critically often because Sentries do a lot of damage - especially removing Spies and their sappers from the Engineer's guns' vicinity. Variants include the Southern Hospitality, implemented with a sharp piece of metal and a spiked handguard, which cause the hit enemy to bleed, the Jag, which hastens building even more but doesn't hurt as much, and the Eureka Effect, which can teleport the Engineer back to spawn or his teleporter exit (and after the ''Meet Your Match'' Update, build teleporters at half cost) at the cost of half the construction speed and half metal from ammo boxes and dispensers.
** Also the default weapon for... guess who... the Engineer in ''VideoGame/TeamFortressClassic''.
* ''VideoGame/SystemShock 2'' has a wrench as a weapon. On the harder difficulties, it's pretty much the best weapon available.
* Since ''VideoGame/{{BioShock}}'' is a {{spiritual successor}} to the ''VideoGame/SystemShock'', it would naturally feature a wrench as the first available weapon. With the right Tonics and Plasmids, the wrench goes from a weak EmergencyWeapon to the sole weapon you use. Tonics can boost the wrench's damage, swing speed, and even give it LifeDrain, meaning you can run headlong into a group of enemies swinging wildly and come out with more health than you had going in. There are also Tonics intended for stealthy players that give ''huge'' damage boosts to the wrench on enemies that aren't aware of your presence... except no stealth is actually required, since stunning an enemy with either Electro Bolt or Insect Swarm will make the game count them as not being aware of you.
** A wrench identical to the one in the first game shows up in ''VideoGame/BioshockInfinite''. [[PlayerCharacter Booker]] doesn't wield it though; [[spoiler: Elizabeth]] knocks him out with it when [[spoiler: she]] finds out he's actually [[spoiler: kidnapping her, not rescuing her]]. Ironically [[spoiler: Elizabeth]] is later [[spoiler: beaten to death]] with a wrench in ''Burial at Sea''.
* Heimerdinger from ''VideoGame/LeagueOfLegends''; he doesn't whack minions and champions with his wrench though, he throws them.
* ''[[VideoGame/DarkCloud Dark Cloud 2]]'' features Max using wrenches as his primary melee weapon from the beginning of the game. It can be upgraded to many different, more combat-designed wrenches, including Smash Wrench, [[ThisIsADrill Drill]] Wrench, and [[PoisonedWeapons Poison]] Wrench.
* Principal Takashi Hanya in ''VideoGame/{{Persona 2}}: Innocent Sin'' uses a giant wrench as a melee weapon.
* Yosuke in ''VideoGame/{{Persona 4}}'' usually has [[DualWielding dual]] [[KnifeNut daggers/kunai]], but can pick up a pair of spanners if you revisit the liquor shop in the TV world. They're also a great weapon for that early in the game thanks to its [[CriticalHit high critical ratio]].
* Wrenches are used by Engineers in ''VideoGame/MakaiKingdom'' with the [[PercussiveMaintenance Tech Bash]] skill, and possibly as an equippable weapon.
* Rocky Wrench from the ''VideoGame/SuperMarioBros3'' airships and their subsequent appearences. Notably, when defeated in ''VideoGame/PaperMarioStickerStar'', they sometimes drop a Wrench sticker that allows Mario to whack people with wrenches too.
* In ''VideoGame/SuperRobotWars'', SuperRobot Gunleon carries a number of these, ranging from ones that are appropriately scaled to fit in its hand like a human's would to a normal wrench, to ''wrench nunchucks,'' to a massive crescent wrench almost as tall as it is. Naturally, these are used to bash or crush enemies, but the largest wrench will occasionally become an enormous crushing clamp... with a PileBunker situated at the joint of its jaws.
* Wrenches appear in all ''VideoGame/{{Fallout}}'' games after the second one, but are only used as weapons in ''Fallout 2'', ''VideoGame/FalloutTacticsBrotherhoodOfSteel'' and ''VideoGame/{{Fallout 4}}''
** ''[[VideoGame/{{Fallout 2}} A typical wrench used by mechanics]] [[VideoGame/FalloutTacticsBrotherhoodOfSteel for hurting people.]]''
** In ''VideoGame/FalloutNewVegas'', a particular quest implies a wrench was used to murder a NCR Engineer for his outfit. Strangely, wrenches still aren't useable as weapons. You can use a [[http://fallout.wikia.com/wiki/Tire_iron_(Fallout:_New_Vegas) lug wrench]] or a [[http://fallout.wikia.com/wiki/Lead_pipe_(Fallout:_New_Vegas) piece]] of [[http://fallout.wikia.com/wiki/The_Humble_Cudgel piping]] but you can't use an adjustable wrench.
** In ''Fallout 4'', the pipe wrench is actually a fairly effective melee weapon at low to mid levels, thanks to the weapon mod system, as it gains mods that not only boost its damage, but also increase its chances of crippling a target or deal extra damage to limbs.
* In ''VideoGame/BanjoKazooie: Nuts & Bolts'', Kazooie carries around a magic Wrench that, aside from carrying stuff around via {{Tractor Beam}}s, can be used as a melee weapon.
** And in ''Banjo Tooie'''s [[EternalEngine Grunty Indutries]] there were worker enemies who'd try to whack the bear and bird with their enormous wrenches.
* One of the bosses in ''VideoGame/MoleMania'' uses wrenches as throwing weapons.
* Lexis in ''VideoGame/LufiaIIRiseOfTheSinistrals'' has wrenches as a main weapon.
* Led from ''VideoGame/SepterraCore'' uses oversized wrenches, not only as a blunt weapon, but also to [[WrenchWench dismantle robotic enemies]].

* TheEngineer in ''{{VideoGame/Torchlight}} 2'' starts with a massive wrench and can find more of them optimized for their class-specific Whacking skills throughout the game.
* In ''VideoGame/ValkyriaChroniclesII'', the Armored Tech class carries an enormous wrench as a melee weapon and multipurpose tool.
* Tinker Knight from ''VideoGame/ShovelKnight'' can toss his spanner like a boomerang in his desperate attempt to defeat the player. Knock his hit-points down enough and he starts throwing ''fountains'' of spanners.
* [[WrenchWench The Mechanic]] in ''{{VideoGame/Terraria}}'' can throw her wench ''like a boomerang'' at nearby enemies.
* Wheeljack uses DualWielding wrenches as his default melee weapon in ''VideoGame/TransformersDevastation''. Functionally, they're similar to dual wielding swords but with slower attack speed.
* In ''VideoGame/Wasteland2'' NPC Angela Deth comes equipped with a wrench as hand-to-hand weapon: it is very effective.
* ''GuildWars2'''s Engineer has the Tool Kit skill that replaces weapons with a wrench used to repair turrets and as a melee weapon, and the ''Heart of Thorns'' expansion adds the Scrapper elite specialization that allows the Engineer to use hammers and along with it two hammer skins in the shape of massive wrenches (that any other class that uses hammers can equip too).

They're apparently as good at [[http://www.girlgeniusonline.com/comic.php?date=20090703 breaking]] [[http://www.girlgeniusonline.com/comic.php?date=20110713 things]] as fixing them.

* In the ''WebComic/{{xkcd}}'' comic [[http://xkcd.com/538/ "Security"]], hypothetical bad guys who want access to someone's files figure that using a wrench for [[TortureAlwaysWorks torture]] would be the {{mundane|Solution}} alternative to intensive hacking.

* ''WesternAnimation/GeorgeOfTheJungle'': Baron Otto Matic of the Tom Slick segment usually uses a wrench to hit his henchman Clutcher with. It's done so often that, when he creates an Irish alter ego to violate a ban, Clutcher says people will figure out it's him if he keeps doing it[[note]]like the Irish name "Ott O'Matic" wouldn't be a dead giveaway[[/note]] and he reacts by using a different object to hit Clutcher with.
* ''WesternAnimation/WackyRaces'': In one occasion, Muttley covers his head with a bucket under the belief that Dick Dastardly will hit him bare-handed (if the gloves he wears don't count) as usual but Dastardly uses a wrench instead.

[[folder:Real Life]]
* Around the turn of the 20th century, many manufacturers such as Bemis & Call designed their monkey wrenches to include a hammerhead on the back side of the wrench. They were meant to be multi-purpose tools rather than being overly specialized. They fell out of favor for lighter designs.
