13 mm 3/8" Drive Universal Semi Deep Socket
This Grey Pneumatic impact socket fits 13 mm metric fasteners with a 3/8 inch square drive. The universal joint allows angled access in confined spaces. Its semi deep profile reaches recessed bolts without the bulk of a full deep socket. The six point opening grips flats securely to reduce rounding.
Practical limits of the universal joint
The swivel adds length and flex, so maximum torque is lower than on a fixed socket. High impact loads can stress the joint pins over time. Clearance around the fastener must accommodate the larger outside diameter of the universal mechanism. It is not suited for continuous heavy duty hammering on seized hardware.
Capacity and headroom for 13 mm fasteners
The 13 mm size covers many common automotive and light industrial bolts. Semi deep depth handles typical stud protrusion and recessed hex heads. For very long studs or deeply recessed fasteners a full deep socket is required. The 3/8 inch drive limits breaker bar leverage compared to larger drive sizes.

Questions about this item
Should I pick the 13mm or another size for my 3/8" drive set?
The 13mm metric socket matches fasteners of that exact size; choose other sizes only if you need different bolt diameters.
How does the universal joint affect reach on a 13mm bolt?
The swivel head lets you work at angles where a straight socket cannot seat, while the semi-deep body still clears the bolt shank.
What does the 6-point drive do for a 13mm impact socket?
Six contact faces spread torque evenly across the fastener flats, reducing rounding risk during high-torque use.
