What this tool is

The Westward 54TM36 is a 3/8" drive hex socket bit with a 5mm tip designed for fastening and loosening metric hex fasteners. It suits mechanics and technicians who need a single, durable bit for regular workshop tasks.

Build and daily use

Alloy steel construction with a full polished chrome finish resists corrosion and cleans easily. The extra-long socket depth and 3-3/4 inch insert length reach recessed bolts, while the 6-point hex profile grips fastener flats securely to reduce rounding.

What it replaces and when to upgrade

This bit replaces shorter or worn 5mm hex drivers that cannot access deep-set fasteners. The jump is worth it when the current tool slips on tight bolts or lacks the reach needed for the job at hand.

What clearance and drive size are needed to fit the 54TM36 in a ratchet or extension?

It requires a 3/8" square-drive ratchet or extension; overall length is 4-13/16" with a 3-3/4" insert length and extra-long socket depth.

How is the hex bit installed and what step is often missed?

Press the 5 mm hex tip into the fastener, engage the 3/8" drive on your ratchet, and ensure the bit seats fully in the extra-long socket before applying torque.
