Value Collection 33630 Hex Socket Cap Screw 3/8-16 Unc 50-pack

Product Description

The VALUE COLLECTION 33630 is a fully threaded hex socket cap screw designed for precision fastening in industrial, mechanical, and trade applications. Sized at 3/8-16 UNC with a 1/2-inch length under head, it is driven with a 5/16-inch hex key. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides a base level of corrosion resistance and reduces light reflection. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, confirming tensile strength and dimensional consistency. Sold in a pack of 50, it suits applications requiring multiple fasteners of this size.

This screw is suited for machinery assembly, equipment mounting, jigs and fixtures, and general mechanical fastening where a recessed drive head and full thread engagement are required. The black oxide alloy steel construction makes it a common choice in shop environments, fabrication settings, and maintenance operations where fasteners see moderate stress loads and controlled indoor conditions.

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for general mechanical and industrial fastening applications where ASME/ANSI B18.3 and ASTM A574 compliant fasteners are specified.

Installation Notes

Installation requires a 5/16-inch hex key or Allen-drive bit. Power down or de-energize any equipment before fastener installation or removal. Apply proper torque using a calibrated torque wrench or driver to avoid fastener damage; consult the equipment manufacturer's torque specification for the joint material and application. Black oxide fasteners are not rated for outdoor or high-moisture environments without additional corrosion protection.
