Value Collection -40884-3 Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION -40884-3 is a fully threaded button socket cap screw designed for fastening applications that require a low-profile head with high clamping strength. Sized at 3/8-16 UNC with a 1-3/4-inch length under head, this screw is machined from alloy steel and finished in black oxide for corrosion resistance and a clean appearance. The hex socket drive accepts a 7/32-inch hex key for installation and removal in tight clearance areas where a standard hex head wrench cannot reach. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards. This package contains 50 pieces.

These button socket cap screws are suited for a wide range of mechanical assembly and maintenance applications including HVAC equipment panels, electrical enclosures, pump housings, brackets, and general industrial assemblies. The button head profile sits flush with or close to the surface, reducing snag points in assemblies where clearance or aesthetics matter. The black oxide finish makes them a common choice in both indoor mechanical and light commercial service environments.

Installation Notes

Installation requires a 7/32-inch hex key or Allen driver. Always verify thread engagement depth and mating thread condition before final torque. Follow applicable equipment manufacturer torque specifications and ANSI/ASME B18.3 guidelines. Use of a thread lubricant or anti-seize compound should be evaluated based on the application and base material.
