Westward 54TL78 12 mm Hex Bit Socket

The Westward 54TL78 is a 3/8 in drive hex bit socket with a 12 mm metric tip. It measures 1 3/4 in overall length with a 3/4 in insert length. The tool is designed for hex screws and bolts in automotive and general mechanical work. It is supplied new and ready for professional or home use.

Replaces worn or missing 12 mm hex bits

A damaged or lost 12 mm hex bit socket slows down fastener work and risks rounding bolt heads. This socket restores the correct fit for metric hex fasteners used in many service tasks. The jump is worth it when the existing bit shows wear, stripped edges or when a dedicated 12 mm size is absent from the set.

Suits mechanics and DIYers needing a single 12 mm

The socket fits 3/8 in drive ratchets and handles common metric hex fasteners. Buyers who need a full range of metric and imperial hex bits or a complete socket set should look at something else. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

What drive size does the 54TL78 need to fit my ratchet?

The 54TL78 uses a 3/8 in drive that fits standard 3/8 in ratchets and extensions.

How do I install the bit socket correctly?

Align the 3/8 in drive square with the ratchet and push until the ball detent clicks; the common error is leaving it partially seated so it pops off under load.

When should I replace the 12 mm hex bit?

Replace the 54TL78 when the 12 mm hex tip shows rounding or wear that lets the bit slip in the fastener head.
