Value Collection 211022PR Flat Socket Cap Screw 5-40

Product Description

The VALUE COLLECTION 211022PR is a flat socket cap screw designed for applications requiring a flush or countersunk head profile. The screw features an 82-degree flat head driven by a 5/64 inch hex socket, making it compatible with standard hex keys and socket drivers. Built from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance for indoor and controlled-environment use. The 5-40 thread size follows UNC standards, and the screw is fully threaded along its 1/4 inch overall length. Licensed trade professionals and experienced assemblers working with precision mechanical assemblies, fixtures, and equipment enclosures will find this fastener suited to tight-tolerance applications.

This screw is suited for use in light mechanical assemblies, electrical enclosures, instrument panels, and fabricated fixtures where a low-profile or flush-mounted fastener is required. The 5-40 UNC thread is commonly found in precision equipment, small machine components, and panel assemblies. The black oxide finish blends into dark metal surfaces and reduces light reflection in optical or instrumentation contexts. This product meets ASME/ANSI B18.3 and ASTM F835 fastener standards, making it appropriate for applications where documented compliance is required.

Key Features

• 82-degree flat head provides a flush or countersunk seating profile
• 5/64 inch hex socket drive compatible with standard hex keys
• Fully threaded along the entire 1/4 inch length for maximum thread engagement
• Alloy steel construction for reliable tensile and shear strength
• Black oxide finish for moderate corrosion resistance and reduced surface reflectivity
• Meets ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed for use in any application accepting a 5-40 UNC fully threaded flat socket cap screw with an 82-degree countersunk head. Minimum order quantity is 100 pieces.

Installation Notes

Installation requires a 5/64 inch hex key or socket driver. The mating material should be tapped to 5-40 UNC specification, and the countersink angle should match the 82-degree head geometry to ensure proper seating and load distribution. De-energize or lock out any equipment before fastener replacement in electrical or mechanical assemblies. Apply only the torque appropriate for the thread size and material being fastened — do not exceed the rated specifications for the alloy steel grade in use.
