Value Collection 201002PR Button Socket Cap Screw 0-80

Product Description

The VALUE COLLECTION 201002PR is a button socket cap screw designed for precision fastening applications requiring a low-profile head and flush or near-flush installation. This screw features a hex socket drive, alloy steel construction, and a black oxide finish that provides moderate corrosion resistance and a clean appearance. The fully threaded shank measures 3/16 inch in length under the head, with a 0-80 UNF thread designation and a 3A thread fit class for controlled, accurate engagement. Hardness is rated at 36-43 HRC. Installation is performed with a hex key or hex driver. It meets ANSI/ASME B18.3 and ASTM F835 standards.

This fastener is suited for applications where minimal head protrusion is required, such as tight mechanical assemblies, instrument housings, light-gauge brackets, and precision equipment enclosures. The 0-80 thread size makes it appropriate for fine, small-scale work commonly encountered in electronics, optical mounts, and instrumentation hardware. Licensed tradespeople and assembly technicians working with miniature hardware typically select this screw when clearance constraints rule out standard or flat-head alternatives. The black oxide coating helps reduce light reflection in optical or low-visibility assemblies.

Key Features

• Button head profile provides low clearance and a smooth, rounded surface finish
• Hex socket drive for positive torque transfer with a standard hex key
• Alloy steel construction with 36-43 HRC hardness for strength under load
• Black oxide coating for mild corrosion resistance and reduced reflectivity
• 3A thread fit class for consistent, precise thread engagement
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style or replacement button socket cap screw for applications specifying a 0-80 UNF fully threaded fastener with a hex socket button head in alloy steel with black oxide finish.

Installation Notes

Installation requires a correctly sized hex key or hex driver to avoid rounding the socket. Ensure mating threads are clean and free of debris before driving the screw. Do not exceed the torque appropriate for the 0-80 thread size and mating material. This fastener is not intended for high-temperature, high-load structural joints without engineering verification.
