Value Collection 211111P Flat Socket Cap Screw 1/4-20 X 1 in

Product Description

The VALUE COLLECTION 211111P is a flat socket cap screw designed for flush or countersunk fastening applications in metalworking, machinery, and general industrial assembly. Featuring a 1/4-20 UNC thread and an overall length of 1 inch, this fastener is fully threaded and machined from alloy steel with a black oxide finish for corrosion resistance. The 82-degree flat head seats flush with the work surface, and the 5/32-inch hex socket drive accepts a standard Allen key for installation. Licensed trades and industrial maintenance technicians rely on this fastener where a low-profile, secure connection is required.

This screw is suited for residential and commercial machine assembly, fixture mounting, and equipment maintenance tasks requiring a countersunk fastener profile. The 1/4-20 UNC thread is one of the most common inch-series thread standards, making this screw compatible with a wide range of pre-tapped components and threaded inserts. The black oxide finish reduces light reflection and provides mild surface protection in dry or mildly humid indoor environments. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• 82-degree flat head seats flush with the work surface for a low-profile, countersunk installation
• 5/32-inch hex socket drive for use with standard Allen or hex key tools
• Fully threaded along the 1-inch overall length for maximum thread engagement
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers mild corrosion resistance and reduced surface glare
• 1/4-20 UNC thread standard per ASME/ANSI B18.3 and ASTM F835

Compatibility

Designed as an OEM-style replacement or standard-duty fastener for any application requiring a 1/4-20 UNC fully threaded flat socket cap screw with an 82-degree head angle, conforming to ASME/ANSI B18.3 and ASTM F835 standards.

Installation Notes

Install using a 5/32-inch hex key or Allen driver; ensure the mating material is tapped or fitted with a threaded insert to the 1/4-20 UNC specification before driving the fastener. Countersink the receiving hole to 82 degrees to achieve a proper flush seating surface. Do not overtighten, as alloy steel fasteners at this diameter can be susceptible to thread stripping in softer base materials. Follow applicable ASME standards and facility safety procedures when performing mechanical assembly or maintenance work.
