3/8-Inch Drive Universal Joint Socket

This TEKTON socket fits a 3/8-inch drive and engages an 18 mm fastener. The universal joint allows the socket to pivot, giving access to bolts at angles where a straight socket cannot reach. It is designed for hand-driven use in automotive and general mechanical work. Mechanics and DIYers who need to work around obstructions will find it useful.

18 mm Capacity With Pivoting Head

The 18 mm opening handles standard metric fasteners of that size. The joint provides enough angular range to clear obstacles while still transmitting torque. Because it is a hand-drive tool, it is not rated for impact use; high-torque applications will exceed its design limits and risk damage. Users should match the socket to the fastener and avoid powered drivers.

Replaces Fixed 3/8-Inch 18 mm Sockets

This socket replaces a fixed 3/8-inch drive 18 mm socket when access is restricted by surrounding components. The upgrade is worthwhile whenever a straight socket cannot seat fully on the fastener due to angle or clearance. It does not substitute for an impact-rated universal joint or a larger-drive tool when higher torque is required.

Questions about this item

Will the 3/8 inch drive on this 18 mm universal joint socket fit my existing 3/8 inch drive ratchet and extensions?

Yes, the 3/8 inch drive square is standard and will connect directly to any 3/8 inch drive ratchet, breaker bar or extension you already own.

How can I confirm the universal joint is moving freely after I attach it to my ratchet?

Rotate the socket head by hand; it should pivot smoothly through its full range without binding or excessive play at the joint.

Does the SHD18118 come only as the single 18 mm universal joint socket, or are additional sockets or a case included?

The box contains only the single 18 mm universal joint socket; no other sockets, rails or storage cases are included.
