Product Information

Tiny Vise® Double Edge Clamps (V Jaws)

The new V-jaw version of our popular Tiny Vise™ is ideal for clamping round workpieces. The 90° V jaw can also be used to clamp a rectangular workpiece from two directions with a single clamp at its corner. Tiny Vise® Double Edge Clamps allow clamping two workpieces at the same time with equal force. These mini edge clamps securely grip the side of a workpiece to keep the top clear for machining. Patented design provides strong, reliable clamping force with the easy turn of a hex wrench. These compact clamps are ideal for fixturing multiple parts, small or large.

These clamps can be set up to apply force either at a downward angle or straight horizontally. Available in four sizes, from 5/16-18 up to a powerful 1"-8 thread size with 4000 lbs clamping force (M8 to M24 in metric). Patent number 5.624.106. Made in USA.

Application Information

Multiple workpieces can be clamped extremely close together with these Double Edge Clamps.

Clamping Action

Clamping force is applied by positive screw action with the easy turn of a hex wrench (not with an unreliable, unsafe eccentric cam as used in other designs). A high-strength cap screw and thrust washer engage a mating countersink to exert strong clamping force. Much more durable than other designs.

Force Equalization

Only Tiny Vise Double Edge Clamps compensate for size variation when clamping two workpieces. Thrust washers have ID clearance to enable them to float horizontally, allowing both clamping jaws to contact their part simultaneously. This ensures that both parts are securely clamped with equal force.

Optional Downthrust Force

Setup for Downthrust Force

(with Bottom Thrust Washer)

Setup for Horizontal Force

(without Bottom Thrust Washer)

Clamps can be set up to apply force either at a downward angle or straight horizontally. All clamps are supplied with an optional bottom thrust washer. Installing this washer under the clamp will raise the clamp slightly and provide downthrust force during clamping. If no downthrust force is required, install the clamp without the bottom thrust washer. Doing so will improve clamping speed because fewer screw turns are required.

Design Considerations

Tiny Vise clamps are designed to provide strong clamping force when tightened by hand. Do not exceed the recommended tightening torque. Recommended torque and clamping force are at 1/3 of yield strength,

leaving 2/3 of holding capacity to resist external cutting forces.

Double edge clamps should always be used to hold two workpieces, not just one; otherwise recommended torque and clamping force will be significantly reduced.
