18-Piece 3/8" Drive Hex Bit Socket Set

This 18-piece set combines metric and SAE hex bit sockets on a 3/8 inch drive for automotive and general mechanical work. Bits are made from S2 alloy steel hardened to 56-62 HRC, while sockets use CRV 50BV30 steel at 38-42 HRC. A chamfered edge design with rounded triangular contact points helps smooth insertion and reduces fastener wear.

Mechanics needing both metric

The set includes ten metric sizes from 3 mm to 10 mm and eight SAE sizes from 1/8 inch to 3/8 inch, covering common fastener ranges. Builders who require larger drive sizes, impact-rated sockets or a ratchet included in the kit should look at other options. The PE storage case measures 252 x 146 x 60 mm and weighs 1.72 kg for portable organisation.

S2 bits handle high torque on stubborn fasteners

The 56-62 HRC hardness gives the bits strong resistance to rounding and breakage under heavy use. Sockets at 38-42 HRC provide sufficient strength for hand-tool applications but are not rated for impact drivers. The chamfered geometry protects both the bit and the fastener head during repeated insertion and removal cycles.

Questions about this item

Does this 3/8" drive hex bit socket set require a specific ratchet or breaker bar to operate?

Any standard 3/8" drive ratchet, breaker bar, or torque wrench will engage the square drive on these sockets. The set includes 18 bit sockets covering metric sizes from 3 mm to 10 mm and SAE sizes from 1/8" to 3/8".

Can I mix these S2 alloy steel bits with my older chrome-vanadium sockets without fit issues?

Yes. Each bit socket is manufactured to standard 3/8" drive dimensions, so they interchange freely with existing Cr-V or other brand sockets. The bits are 56–62 HRC hardness; the socket bodies are 38–42 HRC.

How can I verify the bits are correctly hardened after I start using them?

The bits are heat-treated to 56–62 HRC and the socket bodies to 38–42 HRC. Under normal use they resist rounding and show no deformation on fastener flats; visible wear or rounding would indicate a hardness problem.
