A flat surface area allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings.

Attach threaded accessories, such as mixer propellers and fan blades, to the end of these shafts.

Clip retaining rings into the grooves to separate and position gears, sprockets, and bearings.

Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory.

Clip retaining rings into the grooves to separate and position collars, supports, and housings.

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 fine-threaded rods 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.

These metric threaded rods tighten when turned 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.

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.

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension. Add right- and left-hand threaded rod ends to build your linkages.

Also known as trapezoidal-thread lead screws and nuts.

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.
