Value Collection 211113P Flat Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 211113P is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. It features an 82-degree flat head driven by a 5/32-inch hex socket and is fully threaded at a 1/4-20 UNC thread size with an overall length of 1-1/4 inches. The alloy steel construction with a black oxide finish provides strength and corrosion resistance in general industrial, mechanical, and structural assemblies. Machinists, maintenance technicians, and fabricators install this type of fastener where a low-profile head must sit flush with or below the mating surface.

This screw is suited for residential and commercial mechanical assemblies, machine guarding, jigs, fixtures, and fabrication work where a countersunk socket drive fastener is required. The fully threaded shank provides maximum thread engagement across the entire usable length, making it appropriate for thin-material applications and shallow tapped holes. The black oxide finish reduces light reflection and offers mild surface protection in dry or lightly oiled environments.

Key Features

• 82-degree flat head profile seats flush in standard countersunk holes
• 5/32-inch hex socket drive for precise torque application with a standard hex key
• Fully threaded shank for maximum thread engagement
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Black oxide finish for mild corrosion protection and reduced reflectivity
• UNC thread standard for broad compatibility with standard tapped holes

Compatibility

Designed as an OEM-style or aftermarket replacement flat socket cap screw for standard 1/4-20 UNC tapped holes requiring an 82-degree countersunk flat head seating profile per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 5/32-inch hex key or socket driver. Ensure the mating hole is tapped to 1/4-20 UNC and countersunk to 82 degrees before installation. De-energize or lock out any equipment before fastener replacement on machinery per applicable OSHA lockout/tagout procedures. Do not exceed the rated drive engagement depth when applying torque to avoid stripping the socket recess.
