Hand Wheels

Unthreaded Through-Hole Spoked Hand Wheels

Create custom threads or drill a hole in the side of the hub to secure with a set screw. The spoked design allows a better grip around the rim than solid hand wheels to manually adjust valves, presses, and machine components.

Unthreaded-Hole Spoked Hand Wheels

Tap custom threads or drill a hole in the side of the hub to secure with a set screw. The spoked design allows a better grip around the rim than solid hand wheels to manually adjust valves, presses, and machine components.

Unthreaded Through-Hole Solid Hand Wheels

Create custom threads or drill a hole in the side of the hub to secure with a set screw. Long shafts can pass through these hand wheels for mounting versatility. The wheels are solid, so they won't catch hands or material while manually adjusting valves, presses, and machine components.

Safety Clutch Hand Wheels

To increase operator safety in applications with high shaft speeds, these hand wheels have a clutch that allows a shaft to rotate while the wheel remains stationary. Use them to manually adjust high-speed valves, presses, and machine components.

Dial-Indicating Hand Wheels

An easy-to-read dial provides accurate settings for monitoring the number of wheel turns while manually adjusting valves, presses, and machine components.

Chain-Operated Wheels for Overhead Valves

Open and close almost any hand-wheel operated overhead valve from the floor. These wheels can also be used to operate hatches, skylights, and other overhead components.

Impact-Resistant Chain-Operated
Wheels for Overhead Valves

Made of high-strength ductile iron, these wheels withstand impact better than other wheels to open and close large or stubborn overhead valves from the floor. They can also be used to operate hatches, skylights, and other overhead components.

Knobs

Unthreaded-Hole Knobs

Tap custom threads or secure with a set screw to provide a firm grip to position, tighten, and hold fixtures, equipment, and machinery.

Unthreaded-Hole Knobs with Handle

A handle makes these knobs easy to turn. Tap custom threads or secure with a set screw to provide a firm grip to position, tighten, and hold fixtures, equipment, and machinery.

Square-Through-Hole Knobs

Primarily used on spigot valves, slide these knobs over valves with a square stem and secure them in place with your fastener.

Unthreaded Through-Hole Knobs

Create custom threads or secure with a set screw to provide a firm grip to position, tighten, and hold fixtures, equipment, and machinery. Long shafts can pass through these knobs for mounting versatility.

Indicating Knobs

Turn-Counting Indicating Knobs

For monitoring the number of shaft turns on instrumentation, these knobs have easy-to-read scales or digits for quick and accurate readings. Use them on devices with round shafts.

Comfort-Grip Indicating Knobs

A rubber coating or construction provides a comfortable grip. Use these knobs to control devices with round or D-shaped shafts and view settings at a glance with a pointer.

Dual-Control Comfort-Grip Indicating Knobs

These dual-control knobs operate independently to control two settings. They have a rubber coating for a comfortable grip. Use them on devices with round shafts to view settings at a glance with a pointer.

Indicating Knobs

Control devices with round or D-shaped shafts and view settings at a glance with a pointer.

Choose-a-Color Indicating Knobs

Quickly identify equipment controls and components by their color. Use these knobs to control devices with round shafts and view settings at a glance with a pointer.
