The VALUE COLLECTION 583737PR is a 5/16-18 UNC machine screw designed for general fastening applications across mechanical, structural, and industrial assemblies. The round head slotted drive configuration accepts a standard flat-blade screwdriver and provides a low-profile clamping surface on mating materials. Manufactured from alloy steel with a zinc finish for basic corrosion resistance, this screw measures 1-1/4 inches in length under head. Sold in a minimum order quantity of 100 pieces, this SKU suits contractors, maintenance techs, and shop personnel who require consistent hardware in volume.
This screw is suited for light-to-medium duty fastening where a UNC thread form and round head geometry are specified. Typical applications include securing panels, enclosures, brackets, and mechanical components in HVAC equipment, electrical panels, plumbing fixtures, and general fabrication work. The zinc coating provides a baseline level of protection in dry or mildly humid indoor environments. The 5/16-18 thread size is a common inch-series fastener dimension found throughout commercial and residential trade equipment.
Designed as an OEM-style replacement or service fastener for any application requiring a 5/16-18 UNC round head slotted machine screw with a 1-1/4 inch length under head in alloy steel with zinc finish.
Installation is performed with a standard flat-blade screwdriver sized to match the slotted head. Ensure the mating tapped hole or nut is clean and free of debris before driving. Do not overtighten, as alloy steel zinc-plated screws are not rated for high-torque or high-vibration applications without appropriate locking hardware. Always verify thread engagement and head seating before applying load to the fastened assembly.
