Insulated 12 mm Open-End Wrench
This Wiha Tools open-end wrench is an insulated hand tool sized at 12 mm for electrical and general maintenance tasks. The alloy steel construction provides durability while the high-visibility red and yellow coating allows quick identification in a toolbox or on site. A one-piece handle design gives a secure, comfortable grip during use. It is supplied new and intended for professionals and DIY users who need a reliable insulated wrench.
High-Visibility Coating and One-Piece Handle
The bright red and yellow finish makes the wrench easy to locate among other tools, reducing downtime searching for the right size. The single-piece handle eliminates joints that could loosen over time, preserving the insulated rating and ensuring consistent comfort. Chrome vanadium steel resists wear and corrosion, extending the service life of the tool. These features together improve both safety and efficiency on the job.
12 mm Capacity for Common Fasteners
The 12 mm opening fits many standard nuts and bolts found in electrical panels, automotive work and general assembly. The insulated design allows use on live circuits up to the tool's rated voltage, providing a safety margin for qualified personnel. It is not suited for larger fasteners or applications requiring a box-end or ratcheting mechanism. Buyers needing multiple sizes or different drive styles should consider a set.

Questions about this item
Does the 12 mm open-end wrench have any wearable parts that will need replacing?
No, the one-piece alloy steel construction has no moving or consumable components to wear out.
What stops me from applying more torque with the 20012 wrench during heavy use?
The open-end jaw slips off the fastener before the chrome vanadium steel yields, limiting usable torque.
How hot does the handle get if I keep turning bolts all day with this wrench?
The insulated red and yellow handle stays at ambient temperature because no power or friction heat is generated.
