Hillman Zinc Round Head Combination Machine Screw 1/4"-20 X 4"

Hillman Zinc Round Head Combination Machine Screw 1/4"-20 x 4"

This Hillman zinc-plated round head combination machine screw, size 1/4"-20 x 4", is an extra-long fastener made for dependable metal-on-metal fastening. The machine-cut coarse thread runs the full length of the shank and is sturdier, finer and more precisely made than a wood screw thread. Use it with a matching nut or thread it directly into a tapped hole to assemble machines, tools, brackets and other metal components. The domed round head has a combination drive that accepts both Phillips and slotted screwdrivers, and the zinc plating gives moderate protection against rust and corrosion.
