Apex 80573 Ball Hex Bit Socket Set 3/8 in Drive Metric

Product Description

The APEX 80573 is an 8-piece, 3/8 inch drive long ball end hex bit socket set designed for accessing internal hex fasteners in tight or awkward positions. The base sockets are heat-treated alloy steel for durability and extended tool life. The bits are manufactured from S2 steel for maximum strength. The ball end geometry allows up to a 25-degree entry angle, letting technicians engage fasteners at an offset without slipping. The set covers the full metric range from 3mm through 10mm and ships on a socket rail for organized storage. Licensed trades and serious service technicians reaching recessed fasteners in HVAC equipment, plumbing fixtures, and mechanical assemblies will find this set suited to demanding job-site use.

This socket set is used in residential and commercial service applications where metric internal hex fasteners are common. Typical install scenarios include equipment panels, motor mounts, valve bodies, and structural hardware where standard straight-drive sockets cannot reach due to obstructions or tight clearance. The long-profile design adds reach over standard-length hex bit sockets, and the ball end allows engagement when the tool cannot be held perfectly perpendicular to the fastener. The set arrives ready to use on a socket rail that keeps all 8 sizes indexed and accessible.

Installation Notes

This set is appropriate for use by HVAC technicians, plumbers, electricians, and mechanical service professionals working with metric internal hex fasteners. Always de-energize or lock out equipment before removing fastener-secured covers or components. Confirm the correct socket size seats fully on the fastener before applying torque to avoid rounding. Store on the included rail to prevent loss and maintain quick access during service calls.
