Value Collection MPPI03101500-100BX Machine Screw 5/16-18

Product Description

The VALUE COLLECTION MPPI03101500-100BX is a 5/16-18 x 1.5-inch pan head machine screw designed for general fastening applications across mechanical, HVAC, electrical, and light structural assemblies. Manufactured from Grade 2 steel with a zinc-plated finish, this screw resists corrosion in typical indoor and light-duty service environments. The Phillips drive accepts standard #2 Phillips bits or driver tips. Thread pitch follows the Unified National Coarse (UNC) standard, making it compatible with the widest range of tapped holes and hex nuts in inch-based fastener systems. Length is measured under the head. Sold in a box of 100.

This screw is suited for residential and light commercial installations where a UNC 5/16-18 fastener is required. Common applications include equipment panel assembly, junction box mounting, conduit support hardware, HVAC cabinet fastening, and general equipment bracket work. The pan head profile provides a low-profile bearing surface and works well in applications where a flat or recessed surface is not required. Grade 2 steel is appropriate for non-structural and light-load fastening tasks in non-extreme temperature environments.

• Box of 100 pieces — appropriate quantity for job-site or shop stock

Compatibility

Designed as a standard UNC inch-series machine screw for use in any application requiring a 5/16-18 threaded fastener with a pan head and Phillips drive. No specific model or equipment compatibility was provided in product data.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, plumbers, or general maintenance trades using a #2 Phillips screwdriver or compatible bit driver. Always power down electrical equipment before fastening components in energized enclosures. Do not overtighten into tapped holes in sheet metal or thin-wall materials, as Grade 2 steel and shallow thread engagement can strip under excessive torque. Verify thread engagement depth meets the requirements of the assembly before final tightening.
