Apex 82500 Ball Hex Bit Socket 3/8 in Drive 4 Mm

Product Description

The APEX 82500 is a 3/8 inch drive ball end hex bit socket designed for driving internal hex fasteners in tight or angled positions. The socket base is constructed from heat-treated alloy steel for long-term durability under repeated use. The hex bit is manufactured from S2 steel, which provides high strength and resistance to wear. The ball end geometry allows up to a 25-degree entry angle, making it practical for fasteners that cannot be accessed straight-on. This type of socket is a standard hand-tool item used by mechanics, millwrights, and general trade technicians across a wide range of service applications.

This bit socket is sized for 4 MM metric internal hex fasteners and is suited for use in automotive, mechanical, and industrial maintenance work. The 3/8 inch drive connection is compatible with standard ratchets, extensions, and drive tools in that drive size. At 1.654 inches in length and 0.09 pounds, it is compact enough for use in confined spaces where a full-length tool would be obstructed. Technicians working on equipment with recessed or hard-to-reach fastener locations will find the ball end design particularly useful.

Key Features

• Ball end hex bit allows up to a 25-degree entry angle for angled fastener access
• S2 steel bit construction for high-strength, wear-resistant performance
• Heat-treated alloy steel socket base for durability and extended tool life
• 3/8 inch drive connection for use with standard ratchets and extensions
• 4 MM metric sizing for precise fit on metric internal hex fasteners

Compatibility

Designed for use with 3/8 inch drive ratchets, extensions, and drive handles accepting standard 3/8 inch square drive tooling. Fits 4 MM metric internal hex fasteners.

Installation Notes

This socket is intended for use by mechanics and technicians working on fastened assemblies with internal hex drive points. Ensure the drive tool is fully seated before applying torque to avoid rounding the fastener or damaging the bit. When using the ball end angle, avoid applying excessive side-load force, as this can shorten bit life. Inspect the bit tip for wear before use on precision fasteners.
