Proto J4710SPL Spline Socket 1/4 in Drive 10 Spline

Product Description

The PROTO J4710SPL is a 10-spline socket designed for 1/4 inch drive ratchets and extensions. It accepts a 5/16 inch hex fastener head and features a 12-point internal configuration that provides multiple engagement positions when access is restricted. Weighing 0.03 pounds, this socket is compact enough for tight-clearance fastener work in mechanical and electrical assemblies. It is suited for technicians who need a reliable spline-drive socket in a small drive size for precision fastener applications across HVAC, electrical, plumbing, and general mechanical service work.

This socket fits into service scenarios where 10-spline fasteners appear on equipment panels, component mounting hardware, and access covers. The 1/4 inch drive size makes it a natural choice for torque-sensitive or space-limited fastener positions that larger 3/8 inch or 1/2 inch drive sockets cannot reach. Trade professionals carrying a complete 1/4 inch drive set will find this a functional addition for spline-head fasteners encountered during equipment service calls.

Key Features

• 1/4 inch drive size for use with standard 1/4 inch ratchets, extensions, and adapters
• 10-spline configuration engages spline-head fasteners securely
• 5/16 inch hex size covers a common fastener dimension in mechanical assemblies
• 12-point internal design provides multiple engagement positions in confined spaces
• Lightweight at 0.03 pounds for easy carry in a technician tool kit

Compatibility

Designed for use with standard 1/4 inch drive ratchets, extensions, and torque wrenches. Fits 10-spline, 5/16 inch hex fasteners as encountered in mechanical, HVAC, electrical, and plumbing equipment service applications.

Installation Notes

This socket is installed and used by licensed tradespeople and qualified technicians performing equipment service and fastener removal or installation. Always de-energize equipment and shut off relevant supply lines before beginning fastener work on mechanical assemblies. Verify the socket seats fully on the fastener head before applying torque to prevent rounding the spline profile. Use with a calibrated torque wrench when fastener specifications require controlled torque values.
