Proto J5012DPL Spline Socket 3/8 in Drive 12 Point Deep

Product Description

The PROTO J5012DPL is a deep spline socket designed for 3/8 inch drive ratchets and torque wrenches. It features a 12-spline, 12-point configuration with a 3/8 inch hex size, making it well suited for fasteners that require deeper reach than a standard-depth socket allows. The deep profile engages fasteners seated below surface level or on extended studs, reducing the risk of slippage during high-torque applications. This socket is a hand-tool staple for HVAC techs, plumbers, electricians, and mechanical contractors who work on equipment panels, compressors, flanges, and structural fasteners.

This socket fits standard 3/8 inch drive tool sets and is appropriate for both residential and commercial service work. The 12-point spline design provides multiple engagement positions, which is useful in confined spaces where swing arc is limited. It is a practical addition to any service technician's socket set when deep access to 3/8 inch hex fasteners is required.

Key Features

• Deep socket profile for reaching recessed or stud-mounted fasteners
• 3/8 inch drive compatible with standard ratchets and torque wrenches
• 12-spline, 12-point configuration for multiple engagement positions
• 3/8 inch hex size covers a common fastener dimension across trade applications
• Compact weight of 0.075 pounds for reduced hand fatigue during extended use

Compatibility

Designed as an OEM-style replacement and service socket for use with 3/8 inch drive ratchets, breaker bars, and torque wrenches across general trade and mechanical service applications.

Installation Notes

Installation and removal of fasteners should be performed by a qualified tradesperson following applicable safety procedures for the equipment being serviced. Always power down or de-energize equipment and relieve any system pressure before loosening or tightening fasteners. Confirm the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket for cracks or wear before each use.
