Proto J7440 Impact Socket 1/2 in Drive 1-1/4 in 12-point

Product Description

The PROTO J7440 is a 12-point impact socket designed for use with a 1/2 inch drive impact wrench or ratchet. It fits a 1-1/4 inch fastener and has an overall length of 2 inches. Built for professional use in mechanical, industrial, and trade applications, this socket handles the torque demands of pneumatic and electric impact tools. Licensed tradespeople and shop mechanics rely on sockets like the J7440 for fastener removal and installation in high-load environments where hand-tool sockets would fail under repeated impact cycling.

The J7440 is suited for automotive, heavy equipment, and industrial maintenance work where a 1/2 inch drive impact tool is the standard. Its compact 2 inch overall length allows access in moderately confined spaces. The 12-point design engages a full range of hex fasteners and is commonly used on flange bolts, structural hardware, and drivetrain components in both shop and field service settings.

Key Features

• 1/2 inch drive compatible with standard impact wrenches and ratchets
• 1-1/4 inch socket size for common heavy-duty fasteners
• 12-point geometry provides multiple engagement positions on hex fasteners
• 2 inch overall length suits general-access and semi-confined work areas
• Impact-rated construction handles repeated pneumatic and electric tool cycling

Compatibility

Designed as an OEM-style replacement and standard fitment impact socket for 1/2 inch drive impact wrenches, ratchets, and torque multipliers used in automotive and industrial maintenance applications.

Installation Notes

Installation and removal with this socket should be performed by qualified mechanics or trade professionals using impact-rated drive tools only. Always confirm the socket is fully seated on the fastener before applying torque. Do not use impact sockets with standard hand-tool ratchets beyond their rated capacity, and inspect the socket for cracks or deformation before each use.
