Proto J5324DPL Spline Socket 1/2 in Drive 24 Spline Deep

Product Description

The PROTO J5324DPL is a deep spline socket designed for professional hand-tool applications requiring access to spline-type fasteners. Built on a 1/2 inch drive, this socket fits a 24-spline, 3/4 inch hex fastener and features a 12-point configuration for secure engagement. The deep profile allows reach on recessed or extended fastener installations where a standard-depth socket cannot seat fully. Mechanics, millwrights, and maintenance technicians working on heavy equipment, automotive, and industrial assemblies rely on deep spline sockets for these tight-clearance situations.

This socket is suited for use in automotive repair, fleet maintenance, industrial equipment service, and general mechanical assembly where spline fasteners are encountered. The 1/2 inch drive pairs with standard ratchets, breaker bars, and torque wrenches common in professional shop and field environments. The deep design accommodates studs or threaded rod that would otherwise prevent a shallow socket from seating correctly.

Key Features

• 1/2 inch drive accepts standard ratchets, extensions, and torque wrenches
• 24-spline, 3/4 inch hex sizing for spline-type fastener applications
• 12-point socket design for reliable engagement and torque transfer
• Deep socket profile for recessed fasteners or studs with exposed thread
• Compact weight of 0.33 pounds for reduced hand fatigue during extended use

Compatibility

Designed as a direct-fit spline socket for use with 1/2 inch drive hand tools including ratchets, breaker bars, and torque wrenches requiring a 24-spline, 3/4 inch hex deep socket.

Installation Notes

This socket is installed by mechanics and maintenance technicians as part of standard hand-tool service work. Ensure the drive connection is fully seated in the socket before applying torque to prevent slippage or rounding of the fastener. Inspect the socket for wear or cracks before use, and retire any socket showing visible deformation. Follow applicable torque specifications from the equipment manufacturer when using with a calibrated torque wrench.
