Apex 84878 Impact Socket 3/4 in Drive 6 Point

Product Description

The APEX 84878 is a 3/4 inch drive, 6-point impact socket designed for professional-grade fastener work in demanding trade environments. Constructed from chrome molybdenum alloy steel, the socket delivers the torsional strength and shock resistance required for high-torque impact tool use. A manganese phosphate coating provides corrosion resistance for extended service life. Laser-etched markings paired with a secondary hard stamping keep size identification legible even after heavy use. Off-corner loading geometry reduces fastener rounding during drive, a critical advantage when working with worn or tight hardware.

This socket is suited for heavy mechanical, industrial, and construction applications where a 3/4 inch drive impact wrench is the tool of choice. Typical use cases include structural bolting, heavy equipment maintenance, fleet service, and industrial assembly. The 6-point contact pattern is preferred when maximum torque transfer and minimal fastener damage are priorities. Sold individually, making it straightforward to replace a single socket without purchasing a full set.

Key Features

• Chrome molybdenum alloy steel construction for high-strength, impact-rated durability
• Manganese phosphate coating for corrosion resistance in wet or outdoor environments
• 6-point drive geometry maximizes torque transfer and reduces fastener rounding
• Off-corner loading design reduces risk of rounding worn fasteners
• Laser-etched markings with secondary hard stamping for lasting size identification
• 3/4 inch drive for compatibility with heavy-duty impact wrenches

Compatibility

Designed as a 3/4 inch drive impact socket for use with 3/4 inch drive impact wrenches and breaker bars in professional trade and industrial applications.

Installation Notes

Install and remove using a 3/4 inch drive impact wrench or breaker bar rated for impact use. Always use impact-rated sockets with impact tools — chrome vanadium hand sockets are not rated for impact driver torque and can fracture. Inspect the socket for cracks or deformation before each use and remove from service if damage is found.
