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.

    Quality triple square bit set. Case is convenient to hold and organize the bits when not in use. The 1/2″ drive bits are the security type, hollow tips. For $25, you can’t easily go wrong. For all us shade tree specialists with BMWs, Audis and VWs.

    these are great quality sockets, with a nice little case for them to rest in. For the price you cant go wrong. They were better than i expected. You wont be disappointed. For the price dont wait any longer.

    bought several other sets after buying the long box wrenches seen on “koon trucking” youtube, then buying the 3/8″ impact set having liked the wrenches. those items performed so well i decided to expand into this set, the 88pc master bit set, the master torx set and the 1/2″ impact set. also made sure to purchase everything through Capri’s website to ease any warranty issues down the road. lifetime warranty, but i think it’s going to be a long time if ever that i’ll need it. very nice, very well made, very good finish. all the mechanics in my life drool over this stuff, but they’re still weirded out with online warranty. they like the in person touch from the tool truck guy, even if it’s the bad touch.
