Precision Fastener Access

The Westward 53YR48 is a 1/4 inch drive socket sized at 3/8 inch SAE with a 12-point profile. It targets technicians who need to engage triple-square fastener heads found on certain European vehicle applications. The alloy steel construction provides the hardness required for hand-driven torque.

Sustained Hand Torque

Because the piece is not impact rated, it is designed for steady manual force rather than repeated hammer blows. The 7.2 mm bolt clearance allows the socket to seat fully over protruding threads without binding. ASME B107.110-2012 compliance confirms dimensional accuracy that prevents rounding during prolonged use.

Chrome Alloy Durability

A chrome finish over alloy steel resists corrosion and simplifies cleaning after exposure to shop fluids. The deep-well geometry reaches recessed fasteners without requiring an extension bar in many scenarios. The 1/4 inch square drive fits standard ratchets and breaker bars, keeping the kit lightweight for mobile service work.

Questions about this item

How much heat does the 12-point alloy steel socket generate when used all day with a 1/4 in drive?

As a hand-operated steel socket it produces no heat of its own; any warmth comes from friction in the fastener, not from the tool.

What drive tool must I already own to use the 1/4 in drive 3/8" triple-square socket?

A 1/4 inch square-drive ratchet, breaker bar or T-handle is required; the socket will not fit 3/8 inch or 1/2 inch drives.

Will the 7.2 mm bolt clearance on this SAE socket engage fasteners on older equipment built to earlier ASME standards?

Yes, the 7.2 mm clearance and ASME B107.110-2012 geometry are compatible with legacy SAE triple-square bolts that share the same dimensions.
