Striking wrenches are designed to be hit by a hammer or sledge on the end of the wrench in order to free stubborn nuts or bolts, or to set and tighten. The slugging end of the wrench is relevant to the opening sizes of each wrench. Striking Wrenchesare forged from alloy steel and properly heat-treated to guarantee specific Rockwell hardness for strength and maximum tool life. Straight style Striking Wrenches have greater handle strength and the clearance in overall head diameter the is necessary when working with flange connections. The striking surface is large and smooth to reduce the chance of a glancing blow, and lessens the chance of a rope slipping from the end of the handle when maintaining tension on the wrench. There are also offset striking wrenches available, these are used when working clearance is a problem. Striking wrenches are available in dozens of different sizes so you can easily find the size you need. If you need it, we got it. Always use the right tool for the right job, and always wear your safety equipment.
