3/8-in Drive Hex Socket Bit 4 mm

This Westward 54TM35 socket bit fits a 3/8-inch drive and engages a 4 mm hex fastener. The alloy-steel construction is built for hand-tool use in automotive and general maintenance tasks. The extra-long socket depth reaches recessed bolts where standard bits fall short.

Sustained torque on stubborn fasteners

The extended 4 13/16 in overall length provides additional leverage when breaking loose corroded or over-tightened hex screws. Alloy steel resists rounding under continuous hand-applied force better than shorter, thinner inserts. The fixed, non-replaceable tip eliminates play that can develop under repeated high-load cycles.

Replaces shorter 3/8-in hex bits

Technicians who find standard-length bits cannot reach deep-set hex heads will gain the needed reach without switching to a different drive size. The jump is worth it when clearance around the fastener is tight but depth is the primary obstacle. Buyers needing a replaceable-tip system or impact-rated bits should look elsewhere.

Questions about this item

How much heat does the 3/8 in drive generate during all-day use?

The alloy-steel bit produces no measurable heat during normal hand-tool operation.

What ratchet or breaker bar must I already own for the 3/8 in drive to work?

Any standard 3/8 in square-drive ratchet, breaker bar or torque wrench will engage the socket.

Will the 4 mm hex tip fit hex screws on older equipment I keep?

Yes — the 4 mm hex tip matches the standard metric hex size used on many legacy fasteners.
