Proto J07543M Impact Socket 3/4 in Drive 43mm 6-point

Product Description

The PROTO J07543M is a 3/4 inch drive impact socket designed for heavy-duty fastener removal and installation in professional shop and field environments. Built with a 6-point hex drive profile, this socket delivers solid contact across flat fastener faces, reducing rounding under high torque. It measures 43mm in socket size with an overall length of 2.75 inches, making it appropriate for deep-reach applications where clearance is limited. Weighing 1.93 pounds, the J07543M is machined for impact tool use and is intended for use by mechanics, millwrights, heavy equipment technicians, and industrial maintenance professionals.

This socket is suited for industrial maintenance, heavy equipment service, fleet repair, and manufacturing floor applications where metric fasteners in the 43mm range are common. The 3/4 inch drive size matches high-torque impact wrenches typically used in truck, agricultural, and construction equipment service. The 6-point configuration makes it a reliable choice when working with worn or high-load fasteners that require maximum surface contact to avoid damage during removal.

Key Features

• 3/4 inch drive for use with high-torque impact wrenches
• 43mm socket size for metric fastener applications
• 6-point hex drive profile maximizes contact on fastener flats
• 2.75 inch overall length suits standard and moderate-depth access
• Impact-rated construction for use with pneumatic and electric impact tools

Compatibility

Designed as an OEM-style impact socket for use with 3/4 inch drive impact wrenches and ratchets in professional trade and industrial service applications.

Installation Notes

This socket is intended for installation and removal of fasteners using 3/4 inch drive impact tools. Ensure the impact wrench is powered down and the tool retainer or pin-and-ring is properly engaged before use. Do not use impact sockets with standard hand-drive ratchets, as impact sockets are engineered for dynamic torque loads that differ from hand-tool applications. Always verify socket seating on the fastener before applying torque to avoid slippage or fastener damage.
