Value Collection MPA98164 Flat Head Machine Screw 5-pack

Product Description

The VALUE COLLECTION MPA98164 is a 1/4-20 UNC flat head machine screw designed for general mechanical fastening in trade and industrial applications. At 1-1/4 inches in overall length, this screw is manufactured from 18-8 stainless steel with a bright uncoated finish, providing solid corrosion resistance without plating. The pin-in-torx drive type is a tamper-resistant configuration suited for installations where fastener security is required. This screw ships in a pack of 5 and is appropriate for electricians, plumbers, HVAC technicians, and general contractors who need a reliable stainless fastener in a standard inch thread size.

This flat head machine screw is used wherever a countersunk, flush-mount fastener is needed in metal, plastic, or composite assemblies. The 1/4-20 UNC thread standard is among the most common coarse-thread sizes in North American trade work, making this screw a practical fit for panel mounting, equipment enclosures, junction boxes, brackets, and structural hardware applications. The 18-8 stainless steel construction makes it suitable for indoor and mildly corrosive environments.

Compatibility

Designed as a standard 1/4-20 UNC inch-series flat head machine screw suitable for use with any correspondingly tapped hole, threaded insert, or standard hex or coupling nut in that thread size.

Installation Notes

Installation is appropriate for any qualified tradesperson performing mechanical assembly or equipment mounting. Use a pin-in-torx driver bit sized for the screw drive to prevent cam-out and bit damage. Ensure the mating hole is properly tapped or fitted with a compatible threaded insert before driving. Do not overtighten stainless steel fasteners, as galling can occur — apply anti-seize compound if required by the application.
