3/8" Drive SAE Hex Socket Bit

This Wiha Tools socket bit fits a 3/8" drive and provides a 3/16" SAE hex tip for fastener work. It is machine-pressed from chrome vanadium for strength and durability. The six-sided socket holds the bit securely on all sides so the holder takes the full torque load. It is sold new as a single piece.

Check drive size and tip requirement

Verify that your ratchet or driver uses a 3/8" square drive before ordering. Confirm the fastener calls for a 3/16" SAE hex size. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Replaces worn or missing 3/16" hex bits

This bit replaces a damaged or lost 3/16" SAE hex socket bit in a 3/8" drive set. The upgrade is worth it when the old bit rounds off or no longer grips the fastener securely. It is not suited for metric fasteners or larger SAE sizes.
