Apex 80421 Hex Bit Socket 3/8 Inch Drive Sae

Product Description

The APEX 80421 is a 3/8 inch drive hex bit socket designed for driving and removing internal hex fasteners in professional trade and mechanical service applications. The base socket is constructed from heat-treated alloy steel for durability and extended tool life. The hex bit insert is manufactured from S2 steel, which offers high strength and resistance to cam-out under torque. At 1.85 inches in length and 0.14 pounds, this socket is sized for general-purpose use in tight and standard-access fastening situations. It is sold individually.

This hex bit socket is suited for mechanical, HVAC, plumbing, and electrical service work where internal hex fasteners are common. Typical applications include equipment panels, valve assemblies, motor mounts, and access covers. The 3/8 inch drive size is compatible with standard 3/8 inch drive ratchets, extensions, and torque wrenches found in most field and shop tool sets.

Key Features

• Heat-treated alloy steel base socket for durability and long service life
• S2 steel hex bit insert for maximum strength and torque resistance
• 3/8 inch drive for use with standard ratchets and extensions
• SAE sizing for imperial hex fastener applications
• Compact 1.85 inch length suits both open and restricted-access work

Compatibility

Designed as a standard 3/8 inch drive hex bit socket compatible with 3/8 inch drive ratchets, breaker bars, torque wrenches, and extension bars following SAE drive standards.

Installation Notes

Installation and removal of hex fasteners should be performed by a qualified technician using a calibrated torque wrench where fastener torque specifications apply. Ensure the bit socket is fully seated on both the drive tool and the fastener before applying torque to prevent cam-out or socket slippage. Inspect the S2 bit tip for wear periodically and replace if rounding or deformation is observed.
