Value Collection -40867-3 Button Cap Screw 10-32 7/8 in 50 Pack

Product Description

The VALUE COLLECTION -40867-3 is a 10-32 button socket cap screw designed for secure, low-profile fastening in precision mechanical assemblies. Manufactured from alloy steel with a black oxide finish, this fully threaded fastener measures 7/8 inch in length under the head and is driven with a 1/8-inch hex socket. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it suitable for both functional and finished surfaces. With a hardness rating of 36-43 HRC and a 3A thread fit class, it meets ANSI/ASME B18.3 and ASTM F835 standards. Each package contains 50 screws.

This fastener is used in light machinery, fixtures, enclosures, and equipment panels where a flush or near-flush, rounded head profile is required. The UNF 10-32 thread standard is common in instrument-grade and fine-tolerance applications across industrial, HVAC equipment assembly, electrical enclosure fabrication, and general mechanical maintenance. The hex socket drive allows installation in confined spaces where a wrench cannot reach. Suitable for both OEM production runs and field repair work.

Installation Notes

Installation should be performed with a properly sized 1/8-inch hex key or socket bit to avoid cam-out and head damage. Verify thread engagement depth and mating thread class before driving to ensure proper fit. Follow applicable mechanical or equipment manufacturer torque guidelines for 10-32 fasteners in the target material. Inspect threads on mating components for damage or contamination before installation.
