Product Information
The new V-jaw version of our popular Tiny Vise is ideal for clamping round workpieces. The 90 Degree V jaw can also be used to clamp a rectangular workpiece from two directions with a single clamp at its corner. 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. These clamps 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 USA.
Application Information
Multiple workpieces can be clamped extremely close together. A rectangular workpiece can be clamped from two directions with a single clamp.
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 Flat-Head Socket Screw engages a mating slotted countersink to exert strong clamping force. Much more durable than other designs.
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.
