Value Collection 3TSSF04C008 Flat Socket Cap Screw 4-40

Product Description

The VALUE COLLECTION 3TSSF04C008 is a flat socket cap screw designed for fastening applications that require a flush or countersunk finish. It features an 82-degree flat head with a 1/16-inch hex socket drive and is manufactured from 316 stainless steel, offering strong corrosion resistance in wet, marine, and chemical environments. The thread size is 4-40 UNC with an overall length of 1/2 inch. This fastener is suited for precision assemblies, equipment panels, and enclosures where a low-profile head profile is required. Installation is performed with a standard hex key or Allen driver of the appropriate size.

This screw is used in light-duty mechanical and electrical assemblies, instrument panels, enclosures, and similar applications where a countersunk fastener seat is machined or pre-formed into the mating material. The 316 stainless steel construction makes it appropriate for coastal, marine, pool, and chemical-exposure environments where standard steel fasteners would corrode. Suitable for both original equipment assembly and field repair work performed by maintenance technicians, electricians, and mechanical contractors.

Key Features

• 82-degree flat head provides flush seating in countersunk holes
• 1/16-inch hex socket drive for precise torque application with standard Allen keys
• 316 stainless steel construction for superior corrosion resistance in harsh environments
• 4-40 UNC thread standard ensures broad compatibility with inch-series tapped holes
• Overall length of 1/2 inch suitable for thin panel and light structural fastening

Compatibility

Designed as an OEM-style replacement or stock fastener for applications using 4-40 UNC inch-series tapped holes requiring an 82-degree countersunk flat head profile.

Installation Notes

Installation requires a 1/16-inch hex key or Allen driver. Ensure the mating material has a properly machined 82-degree countersink to achieve full head seating. Power down or de-energize any equipment before accessing fastener locations on electrical panels or enclosures. Do not overtighten small-diameter stainless steel fasteners, as galling can occur; apply an appropriate anti-seize compound when assembling stainless-to-stainless joints.
