Hillman #10 24 tpi 1/2 In. Round Head Combination Machine Screw (100 Ct.)

A machine screw is a fastening screw with a machine-cut thread throughout the length of its shank. Machine screws are used with nuts or screwed directly into a threaded receptacle to fasten various components together in machines, tools, etc. Fasten with a screwdriver to reduce risk of over-tightening and protect the screw and fastened material. If nuts are needed, use with nuts of the same finish and threading for proper fit. The length of a machine screw is measured from under the head to the point of the screw.

• Machine screws are engineered for metal-on-metal fastening applications
• Zinc plating offers moderate protection against rust and corrosion
• Fasten with screwdriver to reduce risk of over-tightening
• For installation, drill a hole in the material that matches the diameter of the bolt, and install with a nut of similar size and finish
• Sturdier thread than wood screws, made finer and more precisely
