Value Collection MS51958-125 Pan Head Machine Screw

Product Description

The VALUE COLLECTION MS51958-125 is a 0-80 pan head machine screw with a Phillips drive, manufactured from 18-8 stainless steel with a black oxide finish. Measuring 7/16 inches in length under the head, this screw conforms to the MS51958 military fastener standard. The 18-8 stainless steel construction provides corrosion resistance in light service environments, while the black oxide finish adds mild oxidation resistance and a uniform dark appearance. This fastener is sold in lots of 100 pieces minimum and is appropriate for use by machinists, electricians, and electronics technicians working with precision assemblies requiring a fine 0-80 thread form.

The MS51958-125 is suited for light-duty mechanical and electronic assemblies where a small-diameter, fine-thread fastener is required. Typical applications include instrument panels, electrical enclosures, PCB standoff mounting, and small equipment chassis work. The pan head profile distributes clamping load over a wider bearing surface than a flat head, making it practical for thin sheet metal or plastic panel applications. This screw is commonly used in aerospace-adjacent, military-spec, and precision instrument service environments.

Key Features

• 0-80 thread size with 7/16 inch length under head for fine-pitch, small-diameter fastening
• 18-8 stainless steel construction for corrosion resistance in non-immersion environments
• Black oxide finish provides uniform appearance and mild surface protection
• Pan head profile increases bearing surface area on thin panels and sheet stock
• Phillips drive compatible with standard drive bits and screwdrivers
• Conforms to MS51958 military fastener standard

Compatibility

Designed as an OEM-style replacement or service fastener for precision assemblies, instrument enclosures, and electrical equipment requiring a 0-80 thread form and MS51958-standard compliance.

Installation Notes

Installation should be performed by a qualified technician familiar with fine-thread fastener handling. Use a properly sized Phillips screwdriver or bit to avoid cam-out and thread damage on this small-diameter screw. Avoid over-torquing, as the 0-80 thread form is susceptible to stripping in soft base materials. Power down all electrical equipment before fastener service on live panels or enclosures.
