Value Collection 1456MPR 1/4-20 X 3.5in Round Head Phillips Screw

Product Description

The VALUE COLLECTION 1456MPR is a 1/4-20 machine screw with a 3.5-inch length under head, round head profile, and Phillips drive. Made from steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J82 standards for dimensional accuracy and mechanical performance. The zinc coating provides basic corrosion resistance for general indoor and light-duty applications. This fastener is used by maintenance technicians, electricians, plumbers, HVAC installers, and general contractors wherever a standard 1/4-20 threaded fastener is required.

This screw is suited for light structural, mechanical, and equipment-assembly applications in residential and commercial settings. It is commonly used to fasten panels, brackets, junction boxes, equipment frames, and similar components where a 1/4-20 thread pattern and Phillips drive are specified. The round head profile sits above the surface and distributes clamping load over a wider area than a flat head. Sold in multiples of 100 per order.

Installation Notes

Install with a Phillips screwdriver or Phillips-tip power driver sized for a No. 2 bit, which is standard for 1/4-20 fasteners of this head size. Ensure the mating thread is clean and properly tapped to 1/4-20 before installation. Power down or de-energize any equipment before fastening panels or enclosures. Do not overtighten — follow the torque requirements specified in the applicable equipment manufacturer documentation or applicable code.
