Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Also known as trapezoidal-thread lead screws and nuts.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start.

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start.

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.

A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end.

Mount these two-piece collars anywhere on an Acme lead screw without removing components.

A set of ball bearings reduces friction and secures the end of a ball or lead screw.

Install these nuts on a rotary shaft to create a linear positioning system without a lead screw. Instead of threads, a set of angled ball bearings drives the nut along a shaft as it spins.

Class 12.9 rods are about 20% stronger than Class 10.9 threaded rods and are for use in heavy machinery.

Grade B7, these threaded rods have a tensile strength about one and a half times stronger than low-strength steel rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Drive and secure these threaded rods on both ends with the included nuts. They’re Grade B7, so their tensile strength is about one and half times higher than low-strength steel rods.

Tighten these threaded rods by turning them to the left; once fastened, they resist loosening from counterclockwise motion. Made from Grade B7 steel, their tensile strength is one and a half times higher than low-strength steel rods.

An economical alternative to Grade B7 and Grade B16 threaded rods, these metric Class 8.8 rods are suitable for fastening most machinery and equipment.

These metric threaded rods are about half the strength of medium-strength steel threaded rods for light duty hanging, mounting, and fastening.

Tighten these threaded rods by turning them to the left; once fastened, they resist loosening from counterclockwise motion. About half the strength of medium-strength steel threaded rods, use them for light duty hanging, mounting, and fastening.

18-8 stainless steel threaded rods have good chemical resistance.

Tighten these threaded rods by turning them to the left; once fastened, they resist loosening from counterclockwise motion.

Stronger and more wear resistant than 18-8 stainless steel, these threaded rods are mildly chemical resistant. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

These metric 316 stainless steel threaded rods are more corrosion resistant than 18-8 and 410 stainless steel threaded rods and have excellent resistance to chemicals and salt water.

Grade B8M threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

The most corrosion resistant stainless steel threaded rods we offer, these Alloy 20 stainless steel threaded rods contain nickel to withstand exposure to sulfuric, phosphoric, and nitric acids.

These metric threaded rods are made from nylon 6/6 and resist oil, grease, and solvents. They’re nonconductive, making them good for use around sensitive electrical components.

These acetal threaded rods won't absorb moisture like nylon and fiberglass rods, so they're good for use in wet environments. They resist alcohol, gasoline, and solvents.

Unlike metal rods, these metric threaded rods will not warp at extreme temperatures, making them ideal for heat treating and furnace fixtures.

PVC threaded rods resist acids, alkalies, salt solutions, and alcohol.

Titanium threaded rods have a high strength-to-weight ratio and are resistant to acids and salt water.

Brass threaded rods are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

Ideal for environments that require frequent cleaning, such as food and pharmaceutical manufacturing, these rods have a removable cover that protects their threads from dirt and grime.

More corrosion resistant than 400 nickel threaded rods, these C276 nickel rods are often used in marine environments and chemical-processing plants.

18-8 stainless steel studs have good chemical resistance and may be mildly magnetic. Also known as hanger bolts, use them to hang, mount, and fasten parts to wood structures.
