Value Collection 40861 Button Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 40861 is a button socket cap screw designed for applications requiring a low-profile head and secure fastening in tight clearance environments. Manufactured from alloy steel with a black oxide finish, this screw delivers corrosion resistance and hardness ratings between 36 and 43 HRC. The hex socket drive accepts a 3/32 inch hex key for installation and removal. Thread size is 8-32 Unified National Coarse, with a length under head of 3/8 inches and a fully threaded shank. Licensed machinists, maintenance technicians, and mechanical assembly professionals typically specify this fastener for machine assemblies, brackets, and equipment panels.

This fastener is suited for light mechanical assemblies in industrial, commercial, and workshop environments. The button head profile reduces snag points and sits flush in countersink-adjacent applications where a standard hex cap would interfere with adjacent components. The black oxide finish is appropriate for indoor and moderate-exposure applications. This screw is sold individually with a minimum order quantity of 50 units, making it appropriate for small batch procurement and inventory replenishment.

Installation Notes

Installation is performed with a 3/32 inch hex key or Allen driver. Confirm the mating thread is clean and free of debris before driving the fastener. Do not exceed the rated torque for an 8-32 alloy steel fastener as specified by your applicable engineering or maintenance standard. Always verify thread fit class 3A compatibility with the receiving thread before final assembly.
