Proto J4714SPL Spline Socket 1/4 in Drive 7/16 in Hex

Product Description

The PROTO J4714SPL is a 12-point spline socket designed for use with a 1/4 inch drive ratchet or torque wrench. The 7/16 inch hex size targets fasteners that require a spline drive interface rather than standard hex or 12-point profiles, delivering more surface contact on the fastener and reducing the risk of rounding. Weighing 0.05 pounds, this socket is compact and suited for tight-access applications where a full-size drive would not fit. It is a purpose-built hand tool intended for professional mechanics, maintenance technicians, and trade professionals working with spline-head fasteners across a range of service tasks.

This socket is appropriate for use in automotive, HVAC, plumbing, and general mechanical service environments where spline fasteners are encountered. The 1/4 inch drive size makes it well suited for light-duty fastening applications and confined spaces where larger drive sizes cannot be used. It fits standard 1/4 inch drive ratchets, extensions, and torque wrenches commonly found in trade tool sets.

Key Features

• 1/4 inch drive size compatible with standard 1/4 inch drive hand tools
• 7/16 inch hex size targets spline-head fasteners
• 12-point spline design provides increased contact area on fastener flats
• Lightweight at 0.05 pounds for easy handling in confined spaces
• Single-piece socket construction for direct ratchet or extension use

Compatibility

Designed as an OEM-style replacement socket compatible with standard 1/4 inch drive ratchets, extensions, and torque wrenches accepting 1/4 inch square drive tooling.

Installation Notes

This socket is installed by trade mechanics and service technicians using standard 1/4 inch drive hand tools. Before use, confirm the fastener head profile matches the spline socket geometry to avoid fastener damage. Always ensure the socket is fully seated on the fastener before applying torque. Inspect the socket for cracks or wear before each use and replace if any deformation is observed.
