Proto J4706SPL Spline Socket 1/4 in Drive 6 Spline

Product Description

The PROTO J4706SPL is a 12-point spline socket designed for use with a 1/4 inch drive ratchet or torque wrench. It accepts a 3/16 inch hex fastener and features a 6-spline internal profile, allowing it to engage fasteners with higher torque transfer and reduced rounding compared to standard hex sockets. The 12-point configuration provides more engagement positions in tight spaces, making it practical for service work in confined areas. Licensed mechanics, HVAC technicians, and plumbers reach for this socket when working with spline-drive or hex-head fasteners on equipment panels, valve stems, and mechanical assemblies.

This socket is suited for light-duty fastener applications requiring a 1/4 inch drive tool setup. It is a compact, single-piece socket appropriate for residential and commercial service environments. Common use cases include equipment access panel fasteners, small-diameter hex bolts on HVAC components, plumbing fixture hardware, and electrical enclosure fasteners. Its small profile and 1/4 inch drive make it a practical addition to a service technician kit where smaller fasteners are common.

Key Features

• 1/4 inch drive interface compatible with standard 1/4 inch drive ratchets and extensions
• 3/16 inch hex size for precise engagement with matching fasteners
• 6 spline socket type for improved torque transfer and reduced fastener rounding
• 12-point configuration allows more ratchet engagement positions in confined spaces

Compatibility

Designed as an OEM-style service socket for use with standard 1/4 inch drive ratchets, extensions, and torque wrenches accepting 3/16 inch hex spline fasteners.

Installation Notes

Install and remove fasteners using a calibrated torque wrench when torque specifications are provided by the equipment manufacturer. Ensure the socket is fully seated on the fastener before applying force to prevent slippage or rounding. Power down or de-energize any equipment before accessing fastened panels or covers. This socket is intended for hand-tool use with 1/4 inch drive equipment only.
