Value Collection 40882 Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 40882 is a fully threaded button socket cap screw designed for fastening applications where a low-profile head is required. It features a 3/8-16 UNC thread and a 7/32 hex socket drive, making it compatible with standard hex keys and Allen wrenches. Manufactured from alloy steel with a black oxide coating, it delivers corrosion resistance and a matte finish suitable for both structural and aesthetic applications. Hardness is rated at 36-43 HRC, conforming to ANSI/ASME B18.3 and ASTM F835 standards. Each package contains 50 screws.

This button socket cap screw is used across a wide range of trade and industrial applications, including mechanical assemblies, equipment panels, machine guards, and structural enclosures. The button head profile sits flush and low against mating surfaces, reducing snag points in tight clearance environments. It is commonly installed by HVAC technicians, electricians, plumbers, millwrights, and general mechanical contractors where a clean, recessed fastener finish is preferred over a standard hex head.

Compatibility

Designed as a standard 3/8-16 UNC button socket cap screw suitable for use in any application requiring an ANSI/ASME B18.3 and ASTM F835 compliant fastener of this thread size and head style.

Installation Notes

Install using a 7/32 inch hex key or socket driver; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Confirm mating threads are clean and free of debris before driving. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener replacement or assembly. As with all alloy steel fasteners with black oxide finish, apply a light oil or thread lubricant in environments with high moisture exposure to extend corrosion resistance.
