The VALUE COLLECTION R50000231 is a slotted round head machine screw designed for general-purpose fastening in metal assemblies, equipment maintenance, and light structural applications. The screw features a 5/16-18 UNC thread form with a 2-inch length under head, providing a reliable and widely compatible fastening option. Constructed from alloy steel with a zinc-plated finish, it offers enhanced corrosion resistance compared to plain steel fasteners. This screw is installed without a washer and is suited for applications where a low-profile round head and slotted drive are specified. Machinists, maintenance technicians, and assembly workers are the typical end users.
This machine screw is appropriate for use in industrial, commercial, and facility-maintenance settings where a 5/16-18 UNC thread engagement is required. Common applications include panel assembly, equipment mounting, fixture fabrication, and general mechanical repairs. The slotted drive accepts a standard flat-blade screwdriver or power driver bit, making it a straightforward choice for routine assembly and service work. It is sold in multiples of 100 units per order.
Designed as a standard 5/16-18 UNC machine screw suitable for use in any application requiring a round head slotted fastener of this thread size and length.
Installation is performed with a flat-blade screwdriver or compatible power driver bit sized for the slotted head. Ensure the mating tapped hole or nut is clean and free of debris before driving. Do not overtighten alloy steel fasteners in softer materials such as aluminum or plastic to avoid thread damage. Follow applicable equipment manufacturer torque guidelines and any relevant industry codes for the specific assembly context.
