Value Collection 211107P Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 211107P is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. With a 1/4-20 UNC thread and an overall length of 5/8 inches, this screw seats fully into a countersunk hole using an 82-degree flat head geometry. Drive engagement is through a 5/32-inch hex socket. Constructed from alloy steel with a black oxide finish, it provides corrosion resistance and reduced light reflection in low-visibility or precision mechanical assemblies. The screw is fully threaded along its entire length, maximizing thread engagement in thin or shallow materials.

This fastener is suited for machine assembly, fixture fabrication, tooling, and equipment maintenance across manufacturing, mechanical, and trade service environments. The flat head profile makes it appropriate for panels, brackets, and components where a protruding fastener head is not acceptable. It meets ASME/ANSI B18.3 and ASTM F835 standards, making it appropriate for structural and mechanical fastening applications where dimensional conformance is required.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 5/32-inch hex socket drive for precise torque application with a standard hex key or Allen driver
• 1/4-20 UNC fully threaded for maximum thread engagement
• Alloy steel construction provides high tensile strength
• Black oxide finish reduces corrosion and surface glare
• Meets ASME/ANSI B18.3 and ASTM F835 dimensional and performance standards

Compatibility

Designed as a standard 1/4-20 UNC flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835, suitable for use in any application that accepts a countersunk hex socket fastener of this thread size and length.

Installation Notes

Installation requires a 5/32-inch hex key or Allen wrench. Ensure the mating hole is countersunk to 82 degrees for proper head seating. Apply thread locking compound or fastener-grade lubricant as required by the assembly specification. Always verify hole depth and thread engagement before applying final torque.
