Proto J5748 1-1/2 Inch 12-point Hand Socket

Product Description

The PROTO J5748 is a 1-1/2 inch, 12-point hand socket designed for heavy-duty fastener work across mechanical, industrial, and trade applications. Built from alloy steel with a satin finish, this standard-length socket measures 2-3/4 inches overall and accepts a 1 inch drive. The 12-point design engages fastener flats at multiple contact points, reducing the risk of rounding under high torque. At 1.08 pounds, it carries the mass expected of a professional-grade tool without unnecessary bulk. It meets ASME B107.110-2012 standards, confirming dimensional and performance compliance for professional use.

This socket is suited for use in mechanical shops, maintenance facilities, and field service environments where 1 inch drive tools are standard. The 1-1/2 inch socket size targets large fasteners common in heavy equipment, structural assemblies, industrial machinery, and commercial HVAC or plumbing installations. The satin finish resists surface corrosion while maintaining a low-glare profile. Licensed mechanics, pipefitters, millwrights, and industrial maintenance technicians are the primary users of this tool.

Key Features

• 12-point geometry provides multiple engagement positions on hex fasteners
• 1 inch drive size compatible with heavy-duty ratchets and breaker bars
• Alloy steel construction rated to ASME B107.110-2012
• Satin finish reduces glare and provides moderate corrosion resistance
• Standard overall length of 2-3/4 inches for general-access fastener work

Compatibility

Designed for use with 1 inch drive ratchets, torque wrenches, and breaker bars. Fits 1-1/2 inch 12-point fasteners in standard-clearance applications. Not tether capable.

Installation Notes

Install and remove using a 1 inch drive ratchet or breaker bar rated for the fastener torque requirement. Ensure the socket seats fully on the fastener before applying force to prevent slippage and fastener damage. De-energize or depressurize the system being serviced before loosening or tightening fasteners on pressurized or energized equipment. Inspect the socket for cracks or wear before each use and remove from service if any damage is found.
