Apex 80574 Ball Hex Bit Socket Set 3/8 in Drive 7 Pc

Product Description

The APEX 80574 is a 7-piece, 3/8 inch drive long ball end hex bit socket set designed for professional use on internal hex fasteners. Sockets are built from heat-treated alloy steel for durability and extended tool life. The bits are manufactured from S2 steel for maximum strength under high-torque applications. The ball end design allows up to a 25-degree entry angle, giving technicians access to hex fasteners in tight or obstructed locations. The set ships on a socket rail for organized storage in a toolbox or service cart.

This set is suited for HVAC, plumbing, electrical, and general mechanical service work where internal hex fasteners are common. Long-length sockets provide additional reach into recessed bolt heads and deep cavities. The SAE sizing range covers the most frequently encountered fractional hex fastener sizes in residential and light commercial equipment. Technicians working on equipment panels, motor mounts, and bracket hardware will find this set covers the majority of common hex fastener sizes encountered on the job.

Installation Notes

Install and remove by a qualified technician using a 3/8 inch drive ratchet or torque wrench appropriate for the fastener specification. Ensure the correct hex size is selected before applying torque to avoid fastener rounding. Inspect S2 bits for wear or deformation periodically and replace any damaged bits before use to prevent fastener damage.
