Value Collection 701005PR Button Socket Cap Screw 0-80

Product Description

The VALUE COLLECTION 701005PR is a button socket cap screw designed for precision fastening applications requiring a low-profile head and a secure hex socket drive. Sized at 0-80 thread with a 3/4-inch length under the head, it is manufactured from alloy steel with a black oxide coating that provides corrosion resistance and a clean matte finish. The fully threaded shank and Class 3A thread fit deliver tight tolerances suitable for close-tolerance assemblies. Hardness is rated at 36-43 HRC. Machinists, tool and die technicians, and mechanical assemblers routinely install this fastener in precision equipment and instrumentation.

This screw is suited for small-scale mechanical assemblies where a flush or recessed head profile is required and space is limited. The 0-80 UNF thread is common in precision instruments, optical equipment, electronics enclosures, and light mechanical assemblies. The black oxide finish makes it a practical choice in applications where surface reflectivity must be minimized or mild corrosion resistance is needed without added dimensional bulk from plating.

Key Features

• Low-profile button head reduces protrusion in tight or surface-critical assemblies
• Hex socket drive accepts standard hex keys for controlled torque application
• Alloy steel construction with 36-43 HRC hardness for strength in small-diameter fasteners
• Black oxide coating provides mild corrosion resistance and non-reflective finish
• Fully threaded shank with Class 3A UNF thread fit for precision engagement
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard-dimension replacement or stock fastener for precision mechanical assemblies using 0-80 UNF threaded hardware per ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers using a correctly sized hex key or hex bit driver. Ensure the mating threaded hole is clean, properly tapped to UNF 0-80 Class 3B tolerances, and free of debris before driving the screw. Avoid over-torquing small-diameter fasteners, as alloy steel screws at this size are susceptible to thread stripping or shank failure when driven beyond the fastener's rated capacity. Follow applicable mechanical assembly standards and equipment manufacturer torque guidelines.
