Value Collection 0412MSF 4-40 X 0.75 in Flat Slotted Machine Screw

Product Description

The VALUE COLLECTION 0412MSF is a 4-40 unified coarse thread machine screw designed for light-duty fastening in metal, plastic, and composite assemblies. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it suitable for applications where a smooth finished surface is required. Drive type is slotted, compatible with standard flat-blade screwdrivers and bit tips. The screw is manufactured from steel with a zinc finish that provides basic corrosion resistance for indoor service environments. It conforms to ASME B18.6.3 and SAE J82 standards. This item is sold in a minimum order quantity of 100 pieces per order.

The 0412MSF is used across a wide range of trade and light industrial applications, including panel assembly, electrical enclosure hardware, HVAC equipment covers, control board mounting, and general sheet metal work. The 4-40 thread size is a standard designation in both electrical and mechanical assemblies where small-diameter, fine-thread fasteners are specified. The 0.75-inch overall length suits typical panel and bracket thicknesses found in residential and light commercial equipment. This screw is installed by electricians, HVAC technicians, and general maintenance technicians alike.

Installation Notes

Install into pre-tapped 4-40 holes or standard 4-40 threaded inserts using a flat-blade screwdriver or appropriately sized bit. De-energize and lock out electrical equipment before working inside panels or enclosures per NFPA 70E safe work practices. Avoid overtightening in plastic or thin sheet metal substrates, as the small thread diameter is susceptible to stripping. Verify hole preparation and thread engagement depth match the 0.75-inch overall length of this fastener before installation.
