Apex 80425 Hex Bit Socket 3/8 Inch Drive 4 Mm

Product Description

The APEX 80425 is a 3/8 inch drive hex bit socket designed for driving and loosening internal hex fasteners in professional and trade applications. The base socket is constructed from heat-treated alloy steel for durability and extended tool life. The hex bit itself is manufactured from S2 steel, which provides high strength and resistance to torsional stress under heavy use. At 1.653 inches in length and 0.13 pounds, this socket is compact enough for tight-access work while still delivering the strength needed for demanding fastener jobs.

This bit socket is suited for use in mechanical, HVAC, plumbing, and electrical trade work where internal hex fasteners are common. It is sold individually and is compatible with any standard 3/8 inch drive ratchet or extension. The 4 MM hex drive size makes it particularly useful for smaller fasteners found on equipment panels, brackets, and component housings across a range of mechanical systems.

Key Features

• Heat-treated alloy steel base socket for durability and long service life

Installation Notes

This socket is installed by hand onto any standard 3/8 inch drive ratchet or extension. Ensure the drive connection is fully seated before applying torque to avoid slippage or fastener damage.
