Value Collection MPRI03101000-100BX 5/16-18x1 in Screw 100pk

Product Description

The VALUE COLLECTION MPRI03101000-100BX is a 5/16-18 x 1 inch round head Phillips machine screw sold in boxes of 100. Manufactured from Grade 2 steel with a zinc-plated finish, these screws meet standard UNC (Unified National Coarse) thread specifications. The round head profile provides a low-profile bearing surface, and the Phillips drive allows for fast installation with standard power tools. Length is measured under the head at 1 inch. These screws are suited for general-purpose fastening in metal, wood, and plastic assemblies across mechanical, HVAC, electrical, and plumbing applications.

These machine screws are commonly used by HVAC technicians, electricians, plumbers, and maintenance professionals for panel fastening, equipment mounting, and structural assembly work. The 5/16-18 UNC thread is a widely used coarse-thread standard, compatible with standard 5/16-18 nuts and threaded inserts. The zinc coating provides basic corrosion resistance for indoor and light-duty outdoor installations. Sold as a box of 100, this quantity suits both shop stock replenishment and recurring field use.

Compatibility

Designed as a general-purpose UNC machine screw compatible with standard 5/16-18 nuts, threaded inserts, and tapped holes conforming to Unified National Coarse thread standards.

Installation Notes

Installation does not require specialized licensing but should follow applicable mechanical and electrical codes when used in regulated assemblies. Use a properly sized Phillips bit to avoid cam-out and head damage. Verify thread engagement depth before final torque to ensure full thread contact. When used in electrical enclosures or panels, confirm screw material and finish are appropriate for the enclosure rating and environment.
