Proto J5740 Hand Socket 1-1/4 Inch 12 Point 1 Inch Drive

Product Description

The PROTO J5740 is a 1-1/4 inch, 12-point hand socket built for professional-grade fastener work. Constructed from alloy steel with a satin finish, it fits a 1 inch drive and measures 2-1/2 inches in overall length, placing it in the standard length category. The 12-point design allows engagement at 30-degree intervals, increasing flexibility in tight access situations. The satin finish reduces glare and resists corrosion in shop and field environments. This socket is intended for use by mechanics, industrial maintenance technicians, and tradespeople who require a reliable, heavy-duty hand socket for large-diameter fasteners.

The J5740 is suited for applications involving large fasteners in industrial, commercial, and heavy equipment maintenance settings. The 1 inch drive makes it appropriate for high-torque work where standard 3/8 inch or 1/2 inch drive tools would be undersized. Typical use cases include structural bolting, heavy machinery servicing, and large flange work. It is not rated as tether capable and should not be used in elevated or overhead applications that require tool-tethering compliance.

Key Features

• 1-1/4 inch socket size for large-diameter fastener applications
• 12-point configuration allows engagement every 30 degrees
• 1 inch drive size rated for high-torque use
• Alloy steel construction for strength and durability
• Satin finish reduces glare and provides corrosion resistance
• Meets ASME B107.110-2012 standards

Compatibility

Designed as an OEM-style replacement for standard 1 inch drive, 12-point hand sockets used in industrial and heavy equipment maintenance applications.

Installation Notes

This socket is installed by mechanics and industrial maintenance technicians using a compatible 1 inch drive ratchet, breaker bar, or torque wrench. Confirm the drive tool is rated for the torque requirements of the fastener before use. Inspect the socket for cracks or wear before each use and replace if deformation is visible. This socket is not tether capable and should not be deployed in elevated work areas where dropped-tool safety programs require tethered tooling.
