Value Collection 211007PR Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 211007PR is a flat socket cap screw designed for precision fastening in tight or flush-mount applications. It features a No. 1-72 UNF thread, an overall length of 1/4 inch, and a fully threaded shank. The 82-degree flat head sits flush with or below the mating surface when properly countersunk, making it well-suited for applications where a protruding head is not acceptable. Made from alloy steel with a black oxide finish, this screw offers solid mechanical strength and moderate corrosion resistance in dry or lightly oiled environments. Typical installers include machinists, electronics technicians, and precision equipment assemblers.

This screw is used in small-scale mechanical assemblies, instrument panels, electronics enclosures, and similar applications that require a low-profile, flush-mount fastening solution. The No. 1-72 thread designation indicates a fine-thread pattern suited for thin materials and applications requiring precise thread engagement. The hex socket drive requires an appropriately sized hex key or Allen driver. This screw conforms to ASME/ANSI B18.3 and ASTM F835 fastener standards, making it compatible with engineered assemblies that specify those standards.

Key Features

• 82-degree flat head for flush or below-surface installation in countersunk holes
• No. 1-72 UNF fully threaded shank for maximum thread engagement over the full 1/4 inch length
• Hex socket drive for high torque application in confined spaces
• Alloy steel construction provides high tensile strength
• Black oxide finish offers mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed as an OEM-style replacement or production fastener for any assembly specifying a No. 1-72 UNF flat socket cap screw per ASME/ANSI B18.3 or ASTM F835.

Installation Notes

Installation requires a correctly sized countersink at 82 degrees to allow the flat head to seat flush. Use the appropriate hex key or Allen wrench to drive the screw — do not use an oversized driver, as this risks stripping the socket. De-energize any equipment and follow applicable safety procedures before servicing assemblies that contain these fasteners. Minimum order quantity for this screw is 100 pieces.
