Value Collection MSCI02500750-100BX 1/4-20 X 3/4 in Screw 100pk

Product Description

The VALUE COLLECTION MSCI02500750-100BX is a 1/4-20 UNC machine screw with a fillister head and slotted drive, sold in a box of 100. Made from Grade 2 steel with a zinc plating finish, this fastener measures 3/4 inches in length under the head. The fillister head profile offers a taller head height and smaller outer diameter compared to a pan head, making it well suited for applications where the fastener must seat inside a recessed hole or close to a shoulder. Zinc plating provides a base level of corrosion resistance for general indoor and light-duty use. This screw is commonly installed by electricians, HVAC technicians, plumbers, and mechanical contractors across a wide range of panel, bracket, and equipment assembly tasks.

This screw is appropriate for light to medium-duty fastening in residential and commercial trade applications. It fits standard 1/4-20 UNC tapped holes and is commonly used to secure electrical panels, HVAC equipment covers, sheet metal brackets, junction boxes, and similar hardware. The slotted drive is compatible with flat-blade screwdrivers and is a standard configuration found throughout trade equipment and fixtures. No washer is included or required under the head for standard installations.

Installation Notes

Install into a pre-tapped or nut-threaded 1/4-20 UNC hole using a flat-blade screwdriver or slotted bit. Verify the mating thread condition before installation to avoid cross-threading. Do not overtighten Grade 2 fasteners in thin sheet metal or soft base materials. Follow applicable NEC, IPC, or equipment manufacturer torque guidelines where specified.
