Proto J77511MP Impact Socket 3/8 in Drive 11mm

Product Description

The PROTO J77511MP is a 12-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. Built from alloy steel, it delivers the toughness required to withstand the high-torque demands of pneumatic and cordless impact tools. The 11mm socket size and 2 inch overall length make it well-suited for fastener work in confined spaces without sacrificing durability. This socket meets ASME B107.2 standards, confirming dimensional and strength compliance for professional use. It is a practical choice for automotive technicians, HVAC service pros, electricians, and plumbers who need reliable metric impact tooling on the job.

This socket is intended for use in general mechanical and trade service applications where an 11mm fastener is common. Typical uses include equipment assembly, panel fastening, and mechanical repairs across residential and light commercial job sites. Its universal style suits a range of impact-driven tasks. The 3/8 inch drive size is a standard in mid-range impact tools, making this socket compatible with a wide variety of tool inventories already found in service vans and shop carts.

Key Features

• 3/8 inch drive fits standard mid-range impact wrenches and ratchets
• 11mm 12-point design engages fastener flats for secure torque transfer
• Alloy steel construction rated for impact tool use
• 2 inch overall length suits both open and moderately confined fastener access
• Meets ASME B107.2 dimensional and performance specification

Compatibility

Designed as an OEM-style replacement or direct-use impact socket compatible with standard 3/8 inch drive impact wrenches, air ratchets, and hand ratchets requiring an 11mm metric socket.

Installation Notes

Install and remove with standard 3/8 inch drive impact tools or hand ratchets. Always ensure the socket is fully seated on the fastener before applying torque to avoid rounding. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with non-impact hand tools in high-torque applications where chrome-finish sockets are required by tool manufacturer guidelines.
