Westward 54TM35 3/8 in Drive Hex Socket Bit 4 mm Tip 4 13/16 in L

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.
