Apex 80164 Hex Bit Socket 1/4 in Drive 4 Mm

Product Description

The APEX 80164 is a 1/4 inch drive hex bit socket designed for driving and removing internal hex fasteners in mechanical and service applications. The base socket is constructed from heat-treated alloy steel for structural durability, while the bit itself is manufactured from S2 steel to handle the torsional demands of high-torque fastener work. At 1.53 inches in length and 0.05 pounds, this is a compact, lightweight tool sized for tight-access work. It is suited for use by HVAC technicians, plumbers, electricians, and general mechanical trades wherever internal hex fasteners are encountered.

This socket fits standard 1/4 inch drive ratchets, extension bars, and torque wrenches. The 4 MM hex bit size covers a common fastener dimension found in equipment panels, motor assemblies, valve bodies, and electrical enclosures. The socket is sold individually and is appropriate for both bench work and field service.

Key Features

• Heat-treated alloy steel base socket for long service life
• S2 steel bit for high torsional strength and wear resistance
• 1/4 inch drive compatible with standard ratchets and extensions
• 4 MM hex bit size for common metric internal hex fasteners
• Compact length of 1.53 inches for use in confined spaces
• Lightweight at 0.05 pounds for reduced hand fatigue during extended use

Compatibility

Designed as an OEM-style replacement and service tool for use with any standard 1/4 inch drive socket system requiring a 4 MM hex bit.

Installation Notes

Ensure the drive tool is fully seated on the socket before applying torque to prevent rounding the drive. Verify the correct hex size before engaging the fastener to avoid damaging the fastener head. Inspect the S2 bit tip for wear or chipping prior to use on critical fasteners. This tool is intended for hand-tool use with a 1/4 inch drive ratchet or torque wrench.
