Value Collection R52001044 1/4-20 X 3/4 in Machine Screw

Product Description

The VALUE COLLECTION R52001044 is a 1/4-20 x 3/4-inch round head machine screw designed for general-purpose fastening in metal, plastic, and wood assemblies. The screw features a slotted Phillips drive, allowing installation with either a flat-blade or Phillips screwdriver. It is manufactured from steel with a zinc plating finish that provides basic corrosion resistance in indoor and light-duty environments. Built to ASME B18.6.3 and SAE J82 standards, this fastener meets established dimensional and mechanical requirements for inch-series machine screws. Length is measured under the head at 3/4 inches. This screw is a standard trade fastener stocked by maintenance technicians, contractors, and assemblers across multiple industries.

This fastener is suited for light-to-medium duty assembly work in residential and commercial applications. Common uses include equipment panel attachment, electrical enclosure assembly, HVAC cabinet fastening, and general mechanical assembly where a 1/4-20 thread is specified. The round head profile provides a low-profile finished appearance on flat surfaces. It is sold individually as a single piece with a minimum order quantity of 100 units, making it appropriate for both small repairs and higher-volume assembly work.
