Universal Joint Socket

This TEKTON 3/8 inch drive socket fits 17 mm fasteners and adds a universal joint for angled access. It suits mechanics and DIYers working in tight engine bays or suspension areas where a straight socket cannot reach.

Chrome Vanadium Construction

The socket is made from chrome vanadium steel with a polished chrome finish that resists corrosion and cleans easily. A 3/8 inch square drive connects to standard ratchets and extensions, while the joint pivots smoothly to maintain engagement on off-axis bolts.

Joint Angle Limitation

The universal joint allows useful deflection but cannot transmit full torque at extreme angles without risk of rounding the fastener or damaging the joint. Users needing maximum leverage on stubborn 17 mm bolts should keep the drive as straight as possible or switch to a fixed socket.

Questions about this item

What does the 3/8 inch drive standard cap in practice?

The 3/8 inch drive limits torque to what that square size can transmit, so the 17 mm universal joint socket suits fasteners within that range.

What physical clearance does the SHD18117 universal joint need to fit?

Its universal joint head adds swing radius beyond a standard socket, so allow extra space around the 17 mm hex for the joint to articulate.

How is this socket installed, and what step is often missed?

Press the 3/8 inch drive end onto the ratchet until the ball detent seats; the missed step is verifying the detent is fully engaged before applying load.
