Value Collection 201001PR Button Socket Cap Screw 0-80

Product Description

The VALUE COLLECTION 201001PR is a 0-80 x 1/8 inch button socket cap screw machined from alloy steel and finished with a black oxide coating. It features a hex socket drive and a low-profile button head with a head height of 0.032 inches. The screw is fully threaded to the head with a UNF thread form and a Class 3A thread fit, providing precise tolerance for close-tolerance assemblies. Hardness runs 36-43 HRC, suitable for applications requiring reliable clamp load in compact fastening situations. Licensed machinists, tool and die makers, and maintenance technicians install this fastener in precision equipment, jigs, fixtures, and light mechanical assemblies.

This screw is sized for applications where a standard cap screw head profile is too tall or too wide. The 0-80 thread is common in miniature mechanical assemblies, optical mounts, instrument enclosures, precision fixtures, and electronics hardware. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it a practical choice for instrumentation and controlled-environment equipment. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• 0-80 UNF thread with Class 3A fit for close-tolerance applications
• Low-profile button head at 0.032 inch head height minimizes protrusion
• Hex socket drive for precise torque application in tight spaces
• Alloy steel construction with 36-43 HRC hardness
• Black oxide coating for mild corrosion resistance and low-reflectance finish
• Fully threaded shank conforms to ANSI/ASME B18.3 and ASTM F835 standards

Compatibility

Designed as an OEM-style fastener for miniature mechanical and precision instrument assemblies using 0-80 UNF threaded hardware.

Installation Notes

Install using a properly sized hex socket driver or hex key to avoid stripping the drive recess on this small-diameter fastener. Ensure mating threads are clean and free of debris before installation. Follow applicable torque guidelines for 0-80 alloy steel fasteners as published by the fastener manufacturer or relevant ASME standards. Do not apply thread-locking compounds that are incompatible with black oxide finishes without verifying compatibility first.
