Hillman Zinc-Plated Round-Head Combination Machine Screws 1/4-20 x 2-1/2" 1/4"-20 x 2-1/2"
Hillman Zinc-Plated Round-Head Combination Machine Screws 1/4-20 x 2-1/2"
Hillman Machine Screws are precision fasteners with a uniform, machine-cut thread running the full length of the shank. Sized 1/4-20 x 2-1/2", they are made to mate with a nut or a threaded hole rather than bite into the material like a wood screw, forming a strong, precise metal-to-metal connection that can be taken apart and reused. That makes them a go-to choice for assembly, mounting, and repair work where parts may need to come apart again later. The domed round head gives a finished look and a broad bearing surface, while the combination drive accepts either a slotted or a Phillips bit for flexibility. A blunt tip and coarse thread turn smoothly into the mating nut or tapped hole, so the larger quarter-inch screw draws up tight for a firm, secure hold. Built from steel with a protective zinc plating, these screws gain light corrosion resistance and a clean silver finish. The plating stands up to everyday handling and dry indoor use, keeping a neat, uniform appearance on brackets, panels, and fixtures over time while helping the threads turn smoothly in the mating nut or tapped hole. Use them for fastening brackets, panels, switch and outlet plates, fixtures, and light machinery wherever a nut or a tapped hole provides the mating thread. They suit appliances, electronics, enclosures, and general repair and assembly. Keep a supply on hand for mounting and repair tasks around the home, shop, and workspace. From the Manufacturer Machine screws are used with nuts or screwed directly into a threaded receptacle to fasten metal parts together. Measured from the underside of the head to the tip of the screw to obtain fastener length. If nuts are needed, use with nuts of the same finish and threading for proper fit.
