Value Collection 1510MSL 1/4-28 X 5/8 Fillister Head Slotted Screw

Product Description

The Value Collection 1510MSL is a 1/4-28 unified fine thread machine screw with a fillister head and slotted drive, manufactured from steel with a zinc finish. The fillister head profile features a small, tall head with a deep slot, making it well-suited for applications where a recessed or closely confined fastener seat is required. At 5/8 inches in length under head, this screw meets ASME B18.6.3 and SAE J82 standards for dimensional accuracy and material grade. It is a standard inch-measurement fastener used across a wide range of mechanical assembly tasks in trade and light industrial settings.

This machine screw is used in residential and commercial mechanical assemblies wherever a 1/4-28 fine thread fastener is specified. The zinc finish provides basic corrosion resistance for indoor and mildly protected environments. Typical applications include securing panels, brackets, junction boxes, motor housings, and control components in HVAC, electrical, and general mechanical work. The slotted drive is compatible with flat-blade screwdrivers and standard slot-drive bits. This SKU is sold as a single piece with a minimum order quantity of 100 units.

Installation Notes

Install with a flat-blade screwdriver or slotted bit driver sized for a 1/4-inch fillister head slot. Ensure the mating threaded hole or nut is tapped to 1/4-28 UNF specification before driving. De-energize all electrical systems and relieve any system pressure before accessing fastened components in live mechanical assemblies. Do not overtighten; torque to the assembly specification provided by the equipment manufacturer.
