Apex 80321 Hex Bit Socket Set 1/4 Inch Drive Metric

Product Description

The APEX 80321 is a 6-piece metric hex bit socket set designed for loosening and tightening internal hex fasteners in professional trade and mechanical service applications. Built on a 1/4 inch drive platform, the set features heat-treated alloy steel base sockets paired with S2 steel bits, delivering the durability and wear resistance that high-cycle use demands. A socket rail is included for organized storage and quick access on the job. The set covers six metric sizes from 2 mm through 6 mm, making it a practical addition to any service kit where metric hex fasteners are common.

This set is suited for automotive, HVAC, plumbing, and general mechanical work where internal hex fasteners are encountered. The 1/4 inch drive size makes it well-matched for confined spaces and lower-torque applications. The included sizes handle the most commonly encountered metric hex fastener range in residential and light commercial equipment service. Licensed trades and service technicians working on equipment panels, access covers, and mechanical assemblies will find the size range practical for day-to-day use.

Key Features

• Heat-treated alloy steel base sockets for long service life under repeated use
• S2 steel bits resist rounding and wear on internal hex fastener drives
• 1/4 inch drive compatible with standard ratchets, extensions, and adapters
• Six-piece metric set covers 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, and 6 mm sizes
