Five-Piece Metric Socket Bit Set

This Westward set supplies five hex socket bits in 8, 10, 12, 14 and 17 mm sizes on a 1/2 inch drive. It is aimed at mechanics and technicians who need a compact selection of common metric fasteners for automotive or industrial work.

Alloy Steel Construction and Chrome Finish

The bits are forged from alloy steel and finished in chrome for corrosion resistance. A female square drive accepts standard 1/2 inch ratchets or breaker bars, while the hex tips engage socket-head cap screws directly without a separate bit holder.

ASME B18.3.2M-1979 Standard

The set conforms to ASME B18.3.2M-1979 for hex socket dimensions. It covers only the five listed sizes, so jobs requiring smaller or larger metric hex bits will need additional pieces. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals.

Questions about this item

What drive size does the 1/2" female square interface accept?

The 1/2" female square drive accepts standard 1/2" drive ratchets and accessories for the 8, 10, 12, 14, and 17 mm hex bits.

What clearance does the 5-7/64 in. overall length need in a socket rail or drawer?

Each bit measures 5-7/64 in. overall, so allow at least that depth plus the ratchet head height when storing in a rail or shallow drawer.

How do you seat the hex tip fully to avoid rounding the 8-17 mm fasteners?

Push the bit onto the fastener until the hex tip bottoms out, then apply steady torque; partial engagement rounds the 8, 10, 12, 14, or 17 mm heads.
