Value Collection 583767PS 5/16-18 X 2-1/4 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 583767PS is a 5/16-18 x 2-1/4 inch round head machine screw designed for general mechanical fastening in trade and industrial applications. Manufactured from alloy steel with a zinc finish for basic corrosion resistance, this screw features a slotted drive and Unified National Coarse (UNC) thread form. The round head profile sits above the work surface without countersinking, making it suitable for through-fastening where a low-profile head is not required. Installers and technicians across HVAC, electrical, plumbing, and general mechanical disciplines reach for this fastener when a standard UNC thread pitch and slotted drive are specified.

This fastener is suited for residential and light commercial mechanical assemblies, equipment panels, junction boxes, and structural brackets where a 5/16-18 UNC thread is called out. The zinc finish provides a measure of protection in dry or mildly humid indoor environments. The 2-1/4 inch length under head accommodates moderate material stack-up without bottoming out in standard threaded holes or nuts. Sold in multiples of 100, this SKU is appropriate for shop stock, service van inventory, or project-quantity procurement.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard tapped holes and hex nuts
• 2-1/4 inch length under head suits moderate material stack-up
• Round head profile requires no countersink preparation
• Slotted drive accepts standard flat-blade screwdrivers and bits
• Alloy steel construction for strength in mechanical fastening applications
• Zinc finish provides basic corrosion resistance in dry indoor environments

Compatibility

Designed as a standard UNC machine screw suitable for use in any application calling for a 5/16-18 thread, round head, and slotted drive in inch-measurement systems.

Installation Notes

Installation is performed by hand or with a standard flat-blade screwdriver or slotted bit driver. Verify the mating thread is 5/16-18 UNC before installation to avoid cross-threading. Power down or de-energize equipment before fastening near electrical components per applicable NEC guidelines. Do not over-torque; confirm torque requirements against the equipment manufacturer's specifications.
