These are Grade 8 threaded rods.

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

These metric Grade B7 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

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

Grade B16 threaded rods maintain their strength at higher temperatures than Grade B7 threaded rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

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.

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

Fiberglass threaded rods are stronger than nylon threaded rods. They resist acids, solvents, salt water, and oil.

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

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.

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

Commonly used in valves, pumps, and shafts, these 400 nickel threaded rods resist salt water and caustic chemicals.

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.

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.

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.

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start metric ball screws and nuts, these have a single thread that runs the length of the screw.

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

Keep your ball screw spinning without the ball nut damaging your system. When the ball nut reaches the stop pin at either end of the ball screw, it disengages and begins to idle.

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.

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

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.

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