The VALUE COLLECTION 588750PR is a 5/16-18 x 2-1/2 inch round head machine screw with a Phillips drive, manufactured from steel with a zinc finish. It meets ASME B18.6.3 and SAE J82 dimensional and performance standards, making it a reliable fastener for general mechanical assemblies. The round head profile sits flush above the mating surface for a clean, low-profile appearance. The zinc finish provides a baseline level of corrosion resistance suitable for indoor and light-duty applications. This screw is used by maintenance technicians, electricians, plumbers, HVAC installers, and other trade professionals in equipment assembly and service work.
This fastener is appropriate for use in residential and light commercial mechanical, electrical, and HVAC equipment assemblies where a 5/16-18 unified coarse thread and Phillips drive are specified. It is suited for securing panels, brackets, and components in sheet metal and machined steel applications. The length under head measures 2-1/2 inches, providing adequate thread engagement for standard material thicknesses. Sold in a minimum order quantity of 10 units per order.
Designed as a general-purpose replacement or service fastener for mechanical assemblies requiring a 5/16-18 coarse thread, round head, Phillips drive machine screw conforming to ASME B18.6.3 and SAE J82 specifications.
Install using a Phillips screwdriver or a Phillips bit with a power driver rated for the fastener size. Ensure the mating threads are clean and free of debris before installation. Do not overtighten, as steel screws with zinc finish can strip threads in softer base materials. Follow applicable equipment manufacturer torque guidelines where specified.
