Tiny Vise® Double Edge Clamps (Serrated Jaws)

Edge Clamps

Product Information

Tiny Vise® Double Edge Clamps (Serrated Jaws) Part # CLM-80-TV Carr Lane Mfg.®

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.

The double edge clamp shown here has serrated faces (for maximum gripping), but is also available with smooth faces (to avoid marring finished parts). 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.

Tiny Vise® Clamps

Tiny Vise® Edge Clamps are the best! These mini edge clamps securely grip the side of a workpiece to keep the top clear for machining. Patented design features a slotted countersink to provide strong, reliable clamping force with the easy turn of a hex wrench. These compact clamps are ideal for fixturing multiple parts, small or large. They look so simple, but work amazingly well, with major advantages over earlier designs.

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.
