Premium S2 Steel

The most durable material to use in bit sockets. Corrosion and oil resistant. Extremely strong and tough for applications where reliability is a top priority. It retains reasonable ductility even in its hardened condition allowing it to perform in applications where shock impact is imparted to the alloy.

Tough Outside,
Strong Inside

We use premium S2 steel tempered with our proprietary heat treatment process to make these bits. They are exceptionally durable and strong, withstand high torque and do not twist, protecting both the bit and the fastener.

  1. Davion

    The sizes you get and the price is just about unbeatable, and the quality is very nice. In my opinion and have withheld being used on my Milwaukee & Snap On Impacts and fit very well in fasteners

  2. ryan.johnston.86 (verified owner)

    I bought a cheap set of these off amazon (not really any cheaper than these and not nearly the quality). I didn’t think that I’d use these that much, but I quickly found out the tolerance son the cheap set were off enough to strip out a bolt. I immediately bought the capri tools set and bolt the bolt out with what was left. Tolerances matter!
