Value Collection MS51958-121B 0-80 Pan Head Phillips Machine Screw

Product Description

The VALUE COLLECTION MS51958-121B is a 0-80 machine screw built to military fastener standard MS51958. It features a pan head with Phillips drive and measures 3/16 inches in length under the head. Constructed from 18-8 stainless steel with a black oxide finish, this screw delivers corrosion resistance with a darkened, low-reflectance surface. The 0-80 thread designation indicates a nominal diameter of 0 gauge with 80 threads per inch, making it appropriate for fine-tolerance fastening in compact assemblies. This fastener is sold individually with a minimum order quantity of 100 pieces.

This screw is suited for precision instrument assembly, electronics enclosures, optical equipment, and other small-component applications where a fine-threaded stainless fastener is required. The black oxide finish makes it a practical choice where glare reduction or a low-profile appearance is a consideration. Technicians working on instrumentation panels, avionics accessories, and similar precision hardware commonly specify this size. The Phillips drive allows use with standard screwdrivers and powered bit drivers in confined spaces.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation fastener for applications requiring a 0-80 threaded, pan head Phillips machine screw per military standard MS51958.

Installation Notes

Installation should be performed by a qualified technician familiar with fine-thread fastener practices. Avoid over-torquing 0-80 screws, as the small thread form is susceptible to stripping in soft base materials. Verify that mating threaded holes or nuts are cut to 0-80 specification before driving. Use a correctly sized Phillips bit to prevent cam-out and fastener head damage.
