Proto J4708DPL Spline Deep Socket 1/4 in Drive

Product Description

The PROTO J4708DPL is a 12-point spline deep socket designed for use with a 1/4 inch drive ratchet or torque wrench. Its spline profile delivers full contact engagement across the fastener flats, reducing rounding on worn or tight fasteners. The deep well design provides clearance for extended bolts, studs, and recessed fastener heads. At 0.04 pounds, it is a lightweight addition to any socket set used in HVAC, electrical, plumbing, or general mechanical service work. Trade technicians and maintenance professionals reach for this socket when working in tight or deep-access locations where a standard-depth socket will not seat properly.

This socket is suited for residential and light commercial service applications where 1/4 inch drive tooling is standard. Common install scenarios include fastening small equipment panels, mounting brackets, and terminal box hardware in HVAC units, electrical enclosures, and plumbing fixtures. The 1/4 inch hex size and 12-point spline configuration make it compatible with a wide range of metric-adjacent and fractional fasteners encountered in trade service calls.

Installation Notes

Install and remove fasteners only after de-energizing electrical equipment or shutting off fluid supply as required by applicable NEC or IPC guidelines. Seat the socket fully onto the fastener before applying torque to avoid slippage and fastener damage. Inspect the spline drive tang and socket bore for wear before each use. This socket should be handled by a qualified technician familiar with the system being serviced.
