Proto J10012L Impact Socket 1 in Drive 3/4 in 6-point

Product Description

The PROTO J10012L is a 1-inch drive, 3/4-inch hex impact socket built for heavy-duty fastening applications where torque output is high and tool failure is not an option. Constructed from alloy steel, this 6-point socket delivers a full 4 inches of overall length, giving technicians the reach needed in deep or recessed fastener locations. The 6-point design concentrates drive force on the flats of the fastener rather than the corners, reducing the risk of rounding under load. At 1.7 pounds, it is sized for use with 1-inch drive impact wrenches common in heavy equipment, fleet, and industrial service work.

This socket is suited for commercial, industrial, and fleet maintenance environments where 1-inch drive tooling is standard. Typical applications include heavy truck axle work, construction equipment service, agricultural machinery repair, and industrial assembly lines. The 3/4-inch hex size addresses fasteners commonly found on large structural and drivetrain components. Licensed mechanics, equipment technicians, and industrial maintenance professionals are the primary installers of this size class.

Key Features

• 1-inch square drive fits standard heavy-duty impact wrenches
• 6-point hex drive geometry reduces fastener rounding under high torque
• Alloy steel construction rated for impact use
• 4-inch overall length provides reach in recessed fastener locations
• 3/4-inch socket size targets large structural and drivetrain fasteners

Compatibility

Designed as an OEM-style replacement or direct-service socket for use with 1-inch drive impact wrenches in heavy-duty automotive, fleet, and industrial applications.

Installation Notes

Always verify the drive tool is powered down or the air supply is disconnected before changing sockets. Confirm the socket seats fully and the retaining pin or ring is engaged before applying torque. Impact sockets are not interchangeable with hand-tool sockets under high-torque impact conditions. Follow applicable workplace safety and tool maintenance standards for impact tooling in your trade environment.
