Apex 80165 Hex Bit Socket 1/4 in Drive 5 Mm

Product Description

The APEX 80165 is a 1/4 inch drive hex bit socket designed for driving and removing internal hex fasteners in professional trade applications. The base socket is manufactured from heat-treated alloy steel for durability and extended tool life. The hex bit itself is made from S2 steel, which provides high impact strength and resistance to rounding under torque. At 1.53 inches in length and 0.05 pounds, this compact socket fits standard 1/4 inch drive ratchets and extension bars. It is sold individually and suited for repetitive fastener work in tight spaces.

This bit socket is appropriate for HVAC, electrical, plumbing, and general mechanical applications where M5 internal hex fasteners are common. Typical use cases include equipment panel assembly, access cover removal, and component mounting work encountered during service calls. The 5 MM hex size is a standard metric fastener size found across a wide range of residential and light commercial equipment.

Installation Notes

This bit socket is used by licensed tradespeople and service technicians across multiple disciplines. Ensure the drive tool is rated for the torque required by the fastener application. Inspect the bit tip for wear before use on critical fasteners, as a worn tip can damage fastener heads. Do not use impact drivers with this socket unless the tool and socket are both rated for impact use.
