Big Enough Wrench?

Let's find out.

There are two ways to figure out if your wrench has enough capacity to achieve the minimum required bolt tension.

  • Bust out the Skidmore, stuff the bolt in it, tighten with your gun until desired tension is achieved or gun stalls out, which ever happens first.
    1. If you reach at least 20% more than the required tension, it should do the job in the steel. 
    2. If it doesn’t, lube assembly or get a bigger gun or both.

  • On a bolt assembly in the steel, tighten with your gun until complete indication is achieved w/ Squirter/DuraSquirt DTI or gun stalls out, which ever happens first.
    1. If complete Squirt indication is achieved, gun is good to go.
    2. If complete Squirt indication is not achieved, lube assembly or get a bigger gun or both (check flat washer requirements and hole type/diameter just in case).

We have a handy guide on our website that can help you choose a wrench with enough capacity to complete the job at hand.
