Proto J10042L Impact Socket 1 in Drive 2-5/8 in 6-point

Product Description

The PROTO J10042L is a heavy-duty 1-inch drive impact socket designed for high-torque fastener work in demanding industrial and mechanical applications. Built from alloy steel, it features a 6-point hex drive design that maximizes contact with fastener flats, reducing rounding under load. The socket measures 2-5/8 inches across the drive and carries an overall length of 5 inches, making it suitable for deep-reach applications. It meets ASME B107.2 standards and is backed by a limited lifetime warranty. Licensed mechanics, millwrights, and heavy equipment technicians are the primary users of this size class.

This impact socket is sized for large-fastener work commonly encountered in heavy truck, agricultural equipment, industrial machinery, and structural assembly applications. The 1-inch drive size pairs with pneumatic or hydraulic impact wrenches used in fleet maintenance shops, construction sites, and manufacturing facilities. The 2-5/8 inch socket size is typical for large hex fasteners found on axle components, large flanges, and heavy structural connections.

Key Features

• 1-inch drive size rated for high-torque impact tool use
• 6-point hex drive geometry reduces fastener rounding under load
• Alloy steel construction for impact-rated durability
• 5-inch overall length provides reach in confined or deep-socket applications
• Meets ASME B107.2 specification for impact sockets
• Limited lifetime warranty coverage

Compatibility

Designed as a standard 1-inch drive impact socket compatible with 1-inch drive pneumatic, hydraulic, and electric impact wrenches. Fits standard square-drive detent-pin or hog-ring retention systems common to 1-inch drive tools.

Installation Notes

Installation and removal should be performed by qualified mechanics using properly rated 1-inch drive impact wrenches. Always verify the impact wrench and socket are rated for the torque being applied before use. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with hand-drive ratchets or torque wrenches, as impact sockets are not designed for that application.
