Proto J15062 Impact Socket 1-1/2 in Drive 3-7/8 in 6-point

Product Description

The PROTO J15062 is a heavy-duty impact socket built for high-torque fastening applications in industrial and mechanical service environments. It features a 1-1/2 inch square drive and a 3-7/8 inch hex opening with a 6-point geometry, which delivers full-face contact on fastener flats to reduce rounding under load. Overall length is 5-1/2 inches. This socket is designed for use with pneumatic, hydraulic, or electric impact wrenches. It is typically installed by industrial mechanics, heavy equipment technicians, and millwrights working on large fasteners in structural, drivetrain, or machinery applications.

The J15062 fits applications requiring a 3-7/8 inch hex socket with a 1-1/2 inch drive, common in heavy equipment maintenance, large-bore flange work, and industrial assembly lines. The 6-point design is preferred in high-torque environments where fastener preservation and slip resistance are critical. It is sold individually and is suited for both shop use and field service where a full-size impact wrench is part of the workflow.

Key Features

• 1-1/2 inch square drive for compatibility with heavy-duty impact wrenches
• 3-7/8 inch 6-point hex socket opening for full-face fastener contact
• 5-1/2 inch overall length provides clearance in deep or recessed fastener locations
• 6-point geometry reduces fastener rounding under high-torque impact loads
• Sold as a single unit with no minimum order beyond one piece

Compatibility

Designed as an OEM-style replacement or service addition for 1-1/2 inch drive impact wrench setups requiring a 3-7/8 inch 6-point hex socket in heavy industrial or equipment maintenance applications.

Installation Notes

Install and remove using a 1-1/2 inch drive pneumatic, hydraulic, or electric impact wrench rated for the fastener torque requirement. Always confirm the socket is fully seated on the drive anvil and the retaining pin or ring is secured before applying torque. Inspect the socket for cracks, chips, or deformation before each use and remove from service if damage is found. Do not use impact sockets on hand-torque tools or vice versa, as the metallurgy and wall thickness differ between impact and hand-socket designs.
