Value Collection 3TSCS04C014 Hex Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION 3TSCS04C014 is a hex socket cap screw designed for precision fastening applications where corrosion resistance and reliable clamping strength are required. Manufactured from 316 stainless steel, this screw features a 4-40 UNC thread size, a 5/32 inch hex drive, and a 7/8 inch length under head. The 316 alloy grade provides superior resistance to chlorides and harsh environments compared to standard 304 stainless. This fastener is suited for use by mechanical assemblers, maintenance technicians, and trade professionals working in corrosive or marine-adjacent environments where material integrity is critical.

This hex socket cap screw is commonly used in light-duty mechanical assemblies, electrical enclosures, instrument panels, HVAC equipment mounting hardware, and precision component assemblies. The 4-40 UNC thread is a fine, small-diameter machine thread widely used in electronics and instrumentation. The socket drive design allows torque application in tight clearances where a conventional hex head wrench cannot reach. This fastener is sold individually with a minimum order quantity of 25 pieces.

Key Features

• 316 stainless steel construction for enhanced corrosion resistance in demanding environments
• 4-40 UNC thread for compatibility with standard small machine screw applications
• 5/32 inch hex socket drive enables torque in confined or recessed spaces
• 7/8 inch length under head suits a range of panel and component thicknesses
• Socket cap head profile provides a low-profile, clean appearance after installation

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring a 4-40 UNC hex socket cap screw with a 7/8 inch length under head in 316 stainless steel.

Installation Notes

Install using a calibrated 5/32 inch hex key or Allen driver to avoid stripping the socket. Ensure the mating threaded hole or nut is clean and free of debris before driving. Do not exceed the rated torque range for 4-40 stainless steel fasteners, as over-torquing small-diameter screws can cause galling or thread failure. Follow applicable mechanical codes and assembly specifications for the equipment being serviced.
