Value Collection 211115P Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 211115P is a flat socket cap screw designed for flush or countersunk fastening applications in metal, wood, and composite assemblies. It features an 82-degree flat head profile and a 5/32-inch hex socket drive, requiring an Allen or hex key for installation. The fastener is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and a low-reflectance appearance. The 1/4-20 UNC thread runs fully along the 1-1/2-inch overall length, making it suitable for through-hole and tapped-hole applications where a protruding head is not acceptable.

This screw is used in a wide range of industrial, mechanical, and fabrication settings where a countersunk fastener is required. Typical applications include machine guards, fixtures, enclosures, tool and die work, and structural assemblies. The black oxide finish is commonly specified in applications where light oil or wax coating will be added post-installation for additional corrosion protection. Installation is performed by machinists, millwrights, maintenance technicians, and general fabricators.

Key Features

• 82-degree flat head profile for flush or countersunk seating
• 5/32-inch hex socket drive for secure torque transfer with standard Allen keys
• Fully threaded 1/4-20 UNC shank along the full 1-1/2-inch overall length
• Alloy steel construction for high tensile strength
• Black oxide finish for low-reflectance surface and light corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard 1/4-20 UNC tapped holes or through-hole assemblies requiring an 82-degree countersunk flat head fastener per ASME/ANSI B18.3.

Installation Notes

Install using a 5/32-inch hex key or Allen driver; ensure the mating countersink is machined to an 82-degree included angle for proper head seating. Power down and de-energize any equipment before servicing fastened assemblies. Apply a compatible thread lubricant or locking compound as required by the assembly specification. Follow applicable machine safety and torque guidelines per the equipment manufacturer or relevant industry standards.
