It’s so very temping to beat normal wrenches with a hammer when a nut or bolt sticks, but doing so is potentially dangerous and can damage the wrench. A striking wrench is designed to take this kind of abuse. Stanley Proto offers a few different options for striking wrenches, including this twelve point offset striking wrench.
The short offset handle allows you to use this wrench in tight quarters. Heavy, box walls and a large striking surface transmit more torque to the fastener, while the box end is designed to stay on the fastener when you strike the wrench. Finished with a black oxide coating to resist corrosion, these wrenches look like they mean business.
Because you strike these tools with a hammer, standard safety precautions apply: use safety glasses, and don’t use a wrench if it shows sign of damage. For better performance, it also helps to use a lubricant or penetrating oil on the fastener.
You can get these wrenches in standard sizes ranging from 1-1/16″ through 3-1/8″ and metric sizes ranging from 32 mm to 80mm — but they don’t come cheap. Depending on the size, you might drop anywhere from a Grant to a few Benjamins for just one wrench.
