The VALUE COLLECTION R63089964 is a 5/16-18 x 1 inch round head slotted machine screw made from brass with a bright, uncoated finish. It uses Unified National Coarse (UNC) threading and is sized with the length measured under the head. The brass construction provides natural corrosion resistance and is well suited for applications where galling with mating threads is a concern. This screw is a standard inch-system fastener used by electricians, plumbers, HVAC technicians, and general trade professionals in light-duty mechanical assembly and panel work.
This fastener is appropriate for residential and light commercial applications where a non-ferrous, slotted round head screw is required. Typical uses include mounting components to enclosures, attaching hardware in corrosion-prone environments, and general mechanical assembly work. The slotted drive accepts a standard flat-head screwdriver, making it accessible with common hand tools in the field.
Designed as a standard inch-system UNC machine screw suitable for use with any 5/16-18 tapped hole, nut, or threaded insert in general mechanical and trade assembly applications.
This fastener is installed by general trade professionals and maintenance technicians using a flat-head screwdriver sized to the slot width. De-energize any electrical equipment and depressurize any plumbing lines before replacing or installing fasteners in live systems. Avoid over-torquing brass screws, as brass is softer than steel and the threads can strip under excessive force. Use a thread lubricant appropriate for brass when torque consistency is required in high-vibration applications.
