About Shafts

Keyed Rotary Shafts

Combine with a machine key to transmit torque to gears, sprockets, and other power transmission components.

D-Profile Rotary Shafts

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

Tapped Rotary Shafts

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure.

Threaded Rotary Shafts

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

Step-Down Rotary Shafts

A shoulder near the end of the shaft provides a stop for gears, sprockets, and bearings.

Rotary Shafts with Retaining Ring Grooves

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

Linear Motion Shafts

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

Threaded Linear Motion Shafts

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.

Step-Down Linear Motion Shafts

A shoulder near the end of the shaft allows for easy positioning of housings, shaft supports, and collars.

Linear Motion Shafts with Retaining Ring Grooves

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

Threaded Rods

High-Strength Steel Threaded Rods

These are Grade 8 threaded rods.

Low-Strength Steel Threaded Rods

About half the strength of medium-strength steel threaded rods, use these for light duty hanging, mounting, and fastening.

Medium-Strength Steel Threaded Rods—Grade B7

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

Left-Hand Threaded Medium-Strength
Steel Threaded Rods—Grade B7

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

18-8 Stainless Steel Threaded Rods

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

18-8 Stainless Steel Threaded Rods—Grade B8

Grade B8 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges. They have good chemical resistance.
