Proto J10056L Impact Socket 1 in Drive 3-1/2 in 6-pt

Product Description

The PROTO J10056L is a heavy-duty impact socket designed for use with 1 inch drive impact wrenches and air tools in demanding trade and industrial applications. Built from alloy steel, it features a 3-1/2 inch hex socket opening with a 6-point drive configuration and an overall length of 6 inches. The 6-point design maximizes contact area on fastener flats, reducing the risk of rounding under high-torque conditions. This socket is suited for mechanics, industrial maintenance technicians, and heavy equipment service professionals who require reliable performance at high drive sizes.

This socket is intended for heavy-duty fastening tasks where a 1 inch drive impact tool is required. Typical applications include heavy equipment assembly, structural fastening, truck and fleet maintenance, and industrial machinery service. The 3-1/2 inch socket size addresses large-format fasteners common in these environments. It is equally at home in a professional shop or on a job site where large-torque impact driving is routine.

Key Features

• Alloy steel construction provides strength and durability in impact applications
• 6 inch overall length offers reach in recessed or tight fastener locations

Compatibility

Designed as an OEM-style heavy-duty impact socket compatible with standard 1 inch drive impact tools and extension bars.

Installation Notes

Installation and removal should be performed by a qualified mechanic or maintenance technician familiar with high-torque impact tooling. Ensure the impact wrench is powered down or the air supply is disconnected before mounting or changing sockets. Inspect the socket for cracks or deformation before each use and replace if damage is found. Do not use impact sockets with hand-drive ratchets, as impact sockets are engineered specifically for the shock loads produced by pneumatic or electric impact tools.
