Value Collection R57001011 Hex Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION R57001011 is a hex socket cap screw designed for secure, flush-profile fastening in applications requiring precise thread engagement. It features a 4-40 UNC thread size, a 1-3/4 inch length under head, and a 3/32 inch hex drive. The fastener is machined from 18-8 stainless steel with a bright, uncoated finish, providing corrosion resistance suitable for general industrial, mechanical, and light trade assembly work. Machinists, maintenance technicians, and mechanical assemblers typically install this screw using a standard hex key or Allen wrench of the appropriate 3/32 inch drive size.

This screw is suited for light-duty threaded fastening in instrumentation panels, electrical enclosures, HVAC control assemblies, plumbing fixtures, and general mechanical assemblies where a fine-thread, small-diameter cap screw is required. The 4-40 UNC thread profile is common in precision equipment and compact mechanical assemblies. The 18-8 stainless steel construction makes it appropriate for indoor and mildly corrosive environments where carbon steel fasteners may be unsuitable.

Key Features

• 4-40 UNC thread for precision, fine-pitch fastening
• 1-3/4 inch length under head provides adequate grip depth for standard panel thicknesses
• 3/32 inch hex socket drive for use with standard Allen keys or hex drivers
• 18-8 stainless steel construction offers corrosion resistance without coating
• Bright, uncoated finish maintains dimensional accuracy for close-tolerance applications

Compatibility

Designed as a standard 4-40 UNC hex socket cap screw replacement suitable for threaded inserts, tapped holes, and assemblies specifying an 18-8 stainless steel socket head cap screw of equivalent thread and length.

Installation Notes

Installation requires a 3/32 inch hex key or Allen driver; use of an incorrect drive size may strip the socket. Always verify the mating thread is clean and free of debris before installation. Do not overtighten into blind tapped holes in soft materials. Minimum order quantity for this fastener is 10 pieces.
