Value Collection MSC-67567925 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION MSC-67567925 is a 1/4-20 x 1/2 inch flat head Phillips machine screw made from 18-8 stainless steel with a bright, uncoated finish. It features a unified national coarse (UNC) thread form and an overall length of 1/2 inch. The flat head profile allows the fastener to sit flush with or below the mating surface when installed in a countersunk hole. These screws are used by electricians, plumbers, HVAC technicians, and general trade contractors wherever a corrosion-resistant, flush-mount fastener is required.

This screw is suited for light-duty to medium-duty fastening applications in residential and commercial settings. The 18-8 stainless steel construction resists corrosion in wet, humid, and mildly corrosive environments, making it appropriate for mechanical enclosures, panel work, plumbing fixtures, equipment housings, and general assembly tasks. The Phillips drive accommodates standard and power-drive installation tools common on most job sites. This item is sold as a single package with a minimum order quantity of 100 pieces.

Compatibility

Designed as a standard 1/4-20 UNC flat head Phillips machine screw compatible with any tapped hole, threaded insert, or hex nut meeting ASME B1.1 inch-series coarse thread specifications.

Installation Notes

Installation of machine screws is typically performed by any trade technician as part of equipment assembly or panel work. De-energize all electrical equipment and relieve system pressure before replacing fasteners on live assemblies. A properly sized countersink must be prepared in the mating material before driving a flat head screw to achieve a flush seating surface. Avoid over-torquing stainless steel fasteners, as 18-8 alloy is susceptible to galling; apply an appropriate anti-seize compound when fastening into stainless or aluminum threads.
