Value Collection MS51958-125B 0-80 Pan Head Phillips Machine Screw

Product Description

The VALUE COLLECTION MS51958-125B is a 0-80 x 7/16-inch pan head machine screw built to military fastener standard MS51958. Machined from 18-8 stainless steel and finished with a black oxide coating, this screw delivers corrosion resistance with a darkened, low-reflectance surface. The pan head profile provides a wide bearing surface and low-profile dome, suitable for close-clearance assemblies. The Phillips drive accepts standard cross-tip bits for fast, positive engagement. Length is measured under the head at 7/16 inches. This item is sold in minimum quantities of 100 per order.

This fastener is used in precision mechanical assemblies, instrument panels, electronics enclosures, and light-duty structural connections where a small-diameter, fine-thread screw is required. The 0-80 thread designation indicates a number 0 diameter with 80 threads per inch, making it one of the finest thread pitches in the inch fastener series. Typical installers include assembly technicians, electronics assemblers, and mechanical contractors working with compact hardware and tight tolerances.

Installation Notes

Installation should be performed with a correctly sized Phillips screwdriver or bit to avoid cam-out on the fine-pitch 0-80 thread. Because this is a fine-thread, small-diameter fastener, care should be taken not to overtorque, which can shear the screw or strip the mating thread. Use a tapped hole or a properly sized nut rated for 0-80 thread engagement. Follow applicable assembly specifications and torque guidelines provided by the equipment manufacturer.
