Proto J5014DPL Spline Socket 3/8 in Drive 14 Spline Deep

Product Description

The PROTO J5014DPL is a deep spline socket designed for professional-grade hand tool use in mechanical, industrial, and maintenance applications. Built for a 3/8 inch drive, this socket accepts 14-spline fasteners with a 7/16 inch hex size and features a 12-point internal configuration. The deep profile allows clearance over longer bolts and studs where a standard-depth socket would bottom out. Weighing just 0.1 pounds, it is a compact addition to any service technician's socket set. Licensed tradespeople and skilled mechanics rely on this type of deep spline socket when working in confined spaces or on assemblies with protruding hardware.

This socket is suited for automotive, heavy equipment, HVAC equipment mounting, and general industrial maintenance work. The 14-spline fitment targets fastener types common in OEM mechanical assemblies where standard hex or 12-point sockets cannot properly engage the fastener profile. The deep configuration makes it practical for wheel bolts, suspension fasteners, and equipment mounting hardware requiring reach beyond a shallow socket's depth. It is sold individually and is compatible with standard 3/8 inch drive ratchets, extensions, and torque wrenches.

Installation Notes

Install and remove fasteners using a calibrated torque wrench when torque specifications are required by the equipment manufacturer. Ensure the socket is fully seated on the fastener before applying force to prevent rounding. Inspect the socket for cracks or wear before use, and do not use impact drivers unless the socket is rated for impact service. Follow applicable equipment service procedures and safety lockout/tagout requirements before beginning fastener work.
