Proto J77411MP Impact Socket 3/8 in Drive 11mm 6-pt

Product Description

The PROTO J77411MP is a 6-point impact socket designed for heavy-duty fastening and removal tasks. Built from alloy steel, it features a 3/8 inch square drive and accepts 11mm hex fasteners. The overall length is 2 inches. This socket is rated to the ASME B107.2 specification, confirming dimensional and performance compliance for professional-grade hand tools. It is suited for use with impact wrenches and drive tools in trade environments where fastener access, torque transfer, and tool durability are daily requirements. Mechanics, electricians, HVAC technicians, and plumbers reaching for a reliable metric impact socket will find this a straightforward, spec-compliant choice.

The J77411MP is applicable across residential and commercial service work wherever 11mm metric fasteners appear. Common scenarios include equipment panel removal, conduit and bracket fastening, motor and compressor mounting hardware, and general mechanical assembly. The 3/8 inch drive size makes it compatible with standard mid-range impact wrenches and ratchets common in field and shop service kits. Its universal style accommodates a wide range of service applications without requiring specialty drive adapters in most setups.

Key Features

• 3/8 inch square drive fits standard mid-range impact wrenches and ratchets
• 11mm hex socket size for metric fastener applications
• 6-point contact geometry reduces fastener rounding under high torque
• Alloy steel construction for impact-rated strength and wear resistance
• 2 inch overall length suits confined-space fastener access
• Meets ASME B107.2 dimensional and performance specification

Compatibility

Designed as an OEM-style impact socket for use with 3/8 inch drive impact wrenches, ratchets, and extensions in professional trade service applications.

Installation Notes

Impact sockets should only be used with impact-rated drive tools. Before use, confirm the socket is fully seated on the drive anvil and that the fastener size matches the socket rating. Never use standard chrome hand-tool sockets in place of impact-rated sockets, as they are not designed to absorb the rotational shock loads generated by impact wrenches. Inspect the socket for cracks or deformation before each use and remove from service if wear is detected.
