Acme Lead Screws and Nuts

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, thread size, and number of thread starts.

Lead Screws—Right-Hand Thread

Alloy Steel—Alloy steel components are harder and stronger than carbon steel components.

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

Threaded Rod and Hex Nut Kits for Pipe Flanges

These kits include the rods and nuts you need to connect standard-size pipe flanges. Their heavy duty material and construction keep tanks, valves, and flanges tightly sealed under heavy pressure. With a 10% wider profile than standard hex nuts, these hex nuts spread force over a larger area and can handle extra torque during installation. The rods are fully threaded to distribute and absorb high levels of clamping force. To ensure your pipe flange connection is tight, add a pipe flange gasket to your installation. These rods and nuts meet a number of rigorous industry specifications for high-pressure performance, high-temperature performance, and dimensional requirements.

Medium-Strength Steel

Image of Product. Front orientation. Threaded Rods. Threaded Rod and Hex Nut Kits for Pipe Flanges, Steel.

With a tensile strength of 125,000 psi, these rods are strong enough for most industrial applications, such as anchoring machinery and connecting pipe flanges. They are about twice as strong as low-strength steel rods.

Steel—Best for dry environments since moisture will cause these rods to rust.

Corrosion-Resistant PTFE-Coated Steel—A PTFE coating protects the steel from corrosion and pitting when exposed to chemicals, such as those found in cleaners and sanitizers. The coating is also slippery to thread on smoothly.
