Value Collection MS51958-122B 0-80 Pan Head Phillips Machine Screw

Product Description

The VALUE COLLECTION MS51958-122B is a 0-80 pan head machine screw with a Phillips drive, manufactured from 18-8 stainless steel with a black oxide finish. The screw measures 0.25 inches in length under the head and conforms to the MS51958 fastener standard, making it a recognized specification part for precision and military-grade assemblies. At 0.00021 pounds per unit, it is suited for lightweight, tight-tolerance applications. The black oxide coating provides mild corrosion resistance and reduces light reflection in applications where glare is a concern. Installation requires a standard Phillips screwdriver or bit driver sized for a 0-80 thread.

This screw is used in applications requiring fine 0-80 unified thread engagement in thin-gauge metal, electronics enclosures, instrument panels, and small mechanical assemblies. The pan head profile provides a wide bearing surface and low-profile head suitable for flush or near-flush mounting in confined spaces. Trades and technicians working on precision equipment, control panels, or instrumentation hardware will find this screw appropriate for those assemblies. Minimum order quantity is 100 pieces per package.

Key Features

• 0-80 thread size for fine-pitch, tight-tolerance fastening applications
• Pan head with Phillips drive for easy installation with standard bit drivers
• 18-8 stainless steel construction for corrosion resistance in indoor and mild-exposure environments
• Black oxide finish reduces surface glare and provides light oxidation protection
• Conforms to MS51958 fastener standard for specification-driven assemblies
• No washer — length measurement taken under the head at 0.25 inches

Compatibility

Designed as an OEM-style replacement or direct specification match for assemblies calling out MS51958-standard 0-80 pan head Phillips machine screws in inch measurement systems.

Installation Notes

Installation should be performed with a properly sized Phillips bit to avoid cam-out on the small 0-80 head. Ensure the mating threaded hole is clean and free of debris before driving. Do not overtighten — 0-80 fasteners have low torque thresholds and the small cross-section is susceptible to shear. Follow the applicable equipment service manual or fastener specification for engagement depth requirements.
