Master Star Bit Socket Set

Made by our most advanced manufacturing process

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.

Chrome Vanadium Steel


The bits are forged with our custom Chrome Vanadium steel, giving them a balance tensile strength for optimal performance.

MaxChrome Finish

Achieved through thorough polishing and careful application of chrome protective plating, ensures durability and corrosion resistance.

Tamper Proof
Bit Sockets

Standard bit sockets but with a unique head, making it nearly impossible to remove with common tools.

6-Point WaveDrive Design

The 6-point WaveDrive design grips fasteners more tightly than traditional design, preventing fastener rounding and giving you more leverage.

Large Stamped Sizing

The stamped sizing is permanent and will not fade over time.


Chamfered bit ensures a smooth fit and help to provide fast and easy insertion into fasteners.

    Nice set. They seem well constructed and they are finished nicely. Time will tell if they hold up but I have no reason to think they won’t.

  2. zachoak (verified owner)

    They work as they should. I’ve put a decent amount of torque on some of these and they haven’t warped yet. Very Happy with purchase because you get every size that anyone would ever need – and then some. Nice set to have for brake jobs.

  3. rioranchonm (verified owner)

    Seem to be very well built, complete set and compared to Snap-on they are an incredible deal.

  4. BRIAN JONES (verified owner)

    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 1/2″ impact set and the 10pc tripple square 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.
