OK VISE
Precision Wedge Clamp Systems

The OK-VISE clamp is a wedge operated clamp. As the screw is tightened, the clamp expands with equal force to both clamping surfaces. The double wedge OK-VISE pulls down on the work piece as it expands out. Small in size and high in clamping force, this low profile clamp is available in many different sizes.

The OK-VISE clamp is precision ground on all moving surfaces to ensure accuracy and ease of adjustment. The heat treated clamping jaws are serrated for better grip. The design of the clamp is excellent for multiple use on pallets and horizontal machines. The heat treated jaws are excellent for clamping rough cut stock and castings. Some clamp models are available with softer jaws for machining to fit special applications such as round pieces or making v-jaws. These clamps use mounting screws from 5/16 to 5/8 diameter.
