Value Collection MS51958-120 Pan Head Machine Screw

Product Description

The VALUE COLLECTION MS51958-120 is a 0-80 pan head machine screw with a Phillips drive, manufactured to the MS51958 military fastener standard. The screw measures 1/8 inch in length under the head and is produced from 18-8 stainless steel, offering corrosion resistance suitable for general industrial and precision assembly applications. The 0-80 thread designation indicates a #0 major diameter with 80 threads per inch, making this one of the finer miniature thread sizes in the inch fastener system. Licensed trades, MRO buyers, and precision assembly technicians typically source this screw in quantity lots for use in instrumentation, electronics enclosures, and light mechanical assemblies.

This screw is appropriate for applications requiring a small-profile pan head and positive Phillips drive engagement in tight clearance environments. The pan head profile provides a low, rounded bearing surface without a washer, suitable for fastening thin sheet material or small components where a flat or oval head is not required. The 18-8 stainless steel construction meets general corrosion-resistance requirements for indoor and light-duty outdoor assemblies. Minimum order quantity is 100 pieces per package.

Installation Notes

Install using a correctly sized Phillips screwdriver or power driver bit to avoid cam-out damage on this miniature thread size. Torque by feel — miniature 0-80 screws have low yield thresholds and are susceptible to thread stripping if over-driven. Power down or de-energize any electrical or electronic assembly before inserting fasteners near live circuits. Follow applicable IPC or equipment manufacturer assembly standards for torque and seating requirements.
