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.
The clamps shown here have both a serrated face (for maximum gripping) and a smooth face (to avoid marring finished parts). They can be set up to apply force either at a downward angle or straight horizontally. Available in a wide range of sizes, from a miniature #8-32 thread size, up to a powerful 1"-8 thread size with 2500 lbs clamping force. Patent number 5.624.106. Made in the USA.
1. The serrated face provides maximum gripping, while the smooth face (turn 180°) avoids marring finished parts.
2. Roll pins can be installed to keep the Tiny Vise perfectly aligned for workpiece loading (especially helpful on horizontal machining centers).
3. For a small amount of cutting-tool clearance, TINY VISE Edge Clamps can be mounted with a spacer underneath, using a longer screw. For greater clearance, clamps should be mounted into a tapped riser block fastened to the plate, to reduce bending stress on the screw.
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 Flat-Head Socket Screw engages a mating slotted countersink to exert strong clamping force. Much more durable than other designs.

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.
Setup for Downthrust Force (with Bottom Thrust Washer)
Setup for Horizontal Force (without Bottom Thrust Washer)
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.
