Value Collection 33637 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 33637 is a hex socket cap screw designed for use in mechanical assemblies requiring a recessed-drive fastener with high tensile strength. Made from alloy steel with a black oxide finish, this screw measures 1.75 inches under the head and is fully threaded with a 3/8-16 UNC thread form. The 5/16-inch hex drive accepts a standard hex key or Allen driver. Black oxide coating provides mild corrosion resistance and reduces light reflection in exposed applications. It meets ASME/ANSI B18.3 and ASTM A574 standards, which specify dimensional and mechanical property requirements for socket cap screws used in industrial and trade applications.

This screw is suited for machinery, equipment frames, jigs, fixtures, and structural assemblies where a low-profile, high-strength fastener is needed. Fully threaded construction makes it practical for through-hole applications and short-grip installations. It is commonly installed by millwrights, pipefitters, HVAC technicians, and general maintenance mechanics working on metal-to-metal connections in both light and heavy industrial settings. Minimum order quantity is 50 pieces per order.

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 3/8-16 UNC fully threaded fastener with a 5/16-inch hex drive.

Installation Notes

Install using a 5/16-inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Power down and de-energize any equipment before replacing fasteners on live machinery. Follow applicable mechanical codes and equipment manufacturer torque guidelines for 3/8-16 socket cap screws in your specific application.
