Adjust machinery components with more leverage and less effort than hand wheels. The through hole in the hub attaches anywhere along the length of shafts. To mount them on unthreaded rods, drill a hole in the side of the hub and secure with a set screw; for threaded rods, tap matching threads inside the hub.

Folding Grip—Handles with a folding grip have a grip that folds out of the way when not in use.

Indexing Grip—Handles with a indexing grip have a pin that fits into indexed holes on equipment such as milling machines and rotary tables.

Recessed-Folding Grip—Those with a recessed folding grip have a grip that folds into the handle to stay fully out of the way.

Revolving Grip—Handles with a revolving grip let you turn continuously without having to adjust your grasp while also reducing strain on your arm.

Stationary Grip—Handles with a stationary grip are best when you need to apply high force because the grip won’t rotate or slip.

302 Stainless Steel—Stainless steel handles have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

Aluminum—Aluminum handles have mild corrosion resistance, are lightweight, and are nonmagnetic.

Iron—Iron handles resist damage from impact.

Nylon—Nylon handles are a lightweight alternative to metal. They resist oil, grease, and solvents.

Zinc—Zinc handles have good corrosion resistance.

Set Screw Starting Hole—Handles with a set screw starting hole have a starting hole in the hub that acts as a guide for drilling a larger hole.

Square Hole


Style 9	Style 10

Square long shafts can pass through these handles for mounting versatility. Drill a hole in the side of the hub to secure with a set screw. These crank handles provide leverage to maximize force for turning and tightening. They are often used on cross-slide tables.

Stationary Grip—Handles with a stationary grip are best when you need to apply high force because the grip won’t rotate or slip.

Revolving Grip—Handles with a revolving grip let you turn continuously without having to adjust your grasp while also reducing strain on your arm.

Iron—Iron handles are powder coated for added durability.

Steel—Steel handles are stronger than iron.

Adjust machinery in tight spaces—the ratcheting action on these crank handles means you don’t have to turn them in complete circles. Flip the control switch to reverse the ratcheting direction. To reduce strain on your arm, these handles have a free-spinning grip. The through hole in the hub attaches anywhere along the length of unthreaded shafts. Handles are black powder-coated steel.

Steel—Steel handles are stronger than iron.

Round Hole with Keyway—Handles with a round hole have an ANSI standard keyway for mounting to keyed shafts.
