Product features and applications

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction, size, and pitch.

Black-oxide carbon steel components have mild corrosion resistance. 932 bearing bronze components are more wear resistant than brass components. They have good machinability and fair corrosion resistance. 360 brass components have excellent machinability and good corrosion resistance.

Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.



are long, solid cylindrical bars that are continuously threaded from end to end with external machine screw threads. Typically 1000 mm (1 meter) long, they are similar to threaded studs but studs are usually less than 200 mm in length. Commonly referred to as "all thread" or "all thread rod," they are used in a variety of fastening applications especially when a long fastener is required but the length exceeds that of available bolts. Being headless, nuts may be used at each end particularly in situations like through-hole bolting and anchoring. Threaded rod can be cut to the desired length although the tips of plated steel rod could then be susceptible to rust (a zinc-rich cold galvanizing compound is sometimes used to coat exposed steel rod ends). Available in steel, Class 4.6 and 8.8; Grade B7 alloy; and stainless steel. Coarse right-hand thread is standard but some types can be supplied with fine and extra fine threads. Finishes for steel are plain finish (unplated and susceptible to rust) and zinc plated. Measure threaded rods from end to end.
