Value Collection R82232881 Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION R82232881 is a 4-40 socket cap screw designed for precision fastening applications in tight-clearance assemblies. The screw features a cylindrical socket cap head driven by a 3/32-inch hex key, allowing torque application in confined spaces where a standard wrench cannot fit. At 0.25 inches length under head, this fastener is suited for shallow-depth through-hole and tapped-hole applications. Manufactured from 18-8 stainless steel with a bright uncoated finish, it offers solid corrosion resistance without plating that could affect thread tolerances. Machinists, maintenance technicians, and equipment assemblers regularly specify this size for instrument panels, electronics enclosures, and light-duty mechanical assemblies.

This screw is a standard #4-40 UNC thread fastener, making it a common choice in precision mechanical, electronic, and instrumentation work. The 0.25-inch under-head length suits thin-gauge panels and shallow tapped holes. The 18-8 stainless steel construction is appropriate for indoor and mildly corrosive environments. It conforms to fastener standard 16995-9d. This SKU is sold individually but carries a minimum order quantity of 10 units, making it practical for both small repairs and production-run sourcing.

Compatibility

Designed as a standard 4-40 UNC socket cap screw suitable for use in any tapped hole or clearance hole application specifying a 4-40 thread with 0.25-inch under-head length.

Installation Notes

Install using a 3/32-inch hex key or T-handle driver. Ensure the tapped hole is clean and free of debris before threading. Avoid over-torquing in shallow tapped holes, particularly in soft materials such as aluminum or plastic. Power down any electrical assembly before fastener service when the screw secures electrically live components.
