Value Collection 0510MSR 5-40 X 5/8 in Round Head Slotted Screw

Product Description

The VALUE COLLECTION 0510MSR is a 5-40 UNC machine screw designed for light-duty fastening applications in metal, plastic, and composite assemblies. The round head profile sits flush against the surface for a low-profile finish, and the slotted drive accepts a standard flat-blade screwdriver. Finished in zinc for basic corrosion resistance, this screw is manufactured from steel to grade J82 and conforms to ASME B18.6.3 and SAE J82 fastener standards. Length under head measures 5/8 inches. Sold individually per package with a minimum order quantity of 100 units, making it well suited for shop stock or production runs.

This screw is used across a wide range of trade and light industrial applications including electrical panel assembly, HVAC equipment, control board mounting, and general mechanical assembly. The 5-40 thread size is common in instrumentation, small appliance, and enclosure work where a compact fastener with a finished appearance is required. Installers in electrical, HVAC, and mechanical trades regularly stock this size for field repairs and equipment reassembly.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to the slotted head. Always de-energize electrical equipment and follow applicable NEC or equipment manufacturer lockout procedures before replacing fasteners in live assemblies. Do not overtighten into tapped holes in soft materials such as aluminum or plastic, as thread stripping can occur. Inspect mating threads for damage before installation.
