The VALUE COLLECTION R50000278 is a flat head slotted machine screw designed for general-purpose fastening in metal and structural assemblies. Sized at 1/2-13 thread and 2 inches in overall length, this screw is manufactured from steel with a zinc plating finish that provides baseline corrosion resistance for indoor and light-duty applications. The flat head profile sits flush with the mating surface when installed into a countersunk hole, making it suitable for applications where a low-profile fastener is required. It meets ASME B18.6.3 and SAE J82 standards, confirming dimensional consistency and material grade compliance. Licensed trades and maintenance professionals rely on this fastener for equipment panels, frames, and mechanical assemblies.
This screw is appropriate for use in light industrial, commercial, and facility maintenance settings where 1/2-13 inch-series fasteners are specified. Typical applications include steel panel attachment, equipment enclosures, structural brackets, and machine component assembly. The slotted drive accepts a standard flat-blade screwdriver, making it accessible with common hand and power tools. It is sold in a minimum order quantity of 50 pieces per order, with each package containing 1 piece, suited to contractors and maintenance shops that stock hardware in bulk.
Designed as a standard 1/2-13 inch-series machine screw suitable for use with matching 1/2-13 threaded nuts, inserts, or tapped holes in steel and compatible substrates following ASME B18.6.3 dimensional requirements.
Installation is performed by maintenance technicians, millwrights, or licensed trades working on mechanical assemblies. Ensure the mating hole is properly tapped or fitted with a compatible 1/2-13 nut or insert before driving. A countersunk hole is required to achieve a flush seating surface with the flat head profile. De-energize and lock out any equipment before fastener work on live machinery in accordance with applicable OSHA lockout/tagout procedures.
