Model Specific Wrench Heads for your Modular Action Wrench

Our Modular Action Wrench Heads are designed to precisely fit your action to ensure proper torque and to protect your action from any damage. Made from 4140 Alloy Steel and heat treated to HRC 32 with a Black Oxide finish. With a low cost, the action wrench heads are quick and tool-less allowing the end user to have one tool that can work on most actions, with out compromise.  
Actions that do not utilize a counterbore on the barrel face will come with a short front bumper to properly locate it in the action. 


One of the best features of our action wrench heads is that they work with most 3/8" Square Drive Extensions that are currently available on the market. 

Simply select the appropriate model number for the action you wish to use. If you do not see your action listed, please contact us, we are always developing new action wrench heads and some actions may work with certain models. We will update the list.

At Short Action Customs, we are only concerned with making the best products. Our Modular Action Wrench comes with a lifetime guarantee against any manufactured defects and has a 100% lifetime replacement for any broken parts. We have thoroughly tested the wrench bodies and they are capable of handling impressive torque values, however we guarantee our parts to handle 150 Ft Lbs of torque. Torquing above 150 Ft Lbs will void your warranty on the wrench body and the wrench heads. The wrench heads are softer than most actions, they will get normal wear and tear, however if any break or crack, we will replace them at no charge.
