Use mounting bases to attach screw clamps to flat surfaces. Their threaded portion is machined at a slightly downward angle so the clamp can get a strong grip on the workpiece. Length is measured from under the screw collar.

Position the arm by adjusting joints at the top, middle, and bottom. A vacuum base provides stability on granite plates and other nonmagnetic surfaces. Use the fine-adjustment knob on the clamp for precise positioning.

Position the arm by adjusting joints at the top, middle, and bottom. The magnetic base has a V-grooved bottom for mounting on curved and flat metal surfaces and a magnetic-release switch for easy setups. Holders have fine-adjustment knobs for precise positioning.

Attach to a machine table to rotate a vise 360°. Base is graduated in 1° increments.

Position the arm by adjusting joints at the top and middle. Use the fine adjustment knob for precise positioning.

Stabilize and precisely position your indicator with these weighted bases. Attached to the base, these holders have a jointed arm for moving your indicator up and down and in and out. Tighten the knob on the arm to lock it in place and use the fine-adjustment clamp for angling your indicator just right. Made of granite, the base has an extremely tight flatness tolerance, so it creates an accurate reference point for inspection work. It also means you can easily slide your workpiece in and out.

Mount the clamp in a threaded hole or on a mounting base.

Jointed at the top, middle, and bottom, the arm holding these variance indicators adjusts to various angles. Turn the knob on the fine-adjustment clamp to angle them precisely. With a magnetic V-grooved base, they mount securely to both flat and curved metal surfaces. A spring-loaded plunger retracts and extends to measure objects. These indicators have a continuous dial numbered clockwise around the face, so it’s easy to see how much a dimension increases. Adjust the tolerance pointers to mark measurements that fall outside your limits. For quick dismounting, the base has a magnetic release switch.

Mount this holder into your machine spindle and use for centering workpieces. The clamp has a fine-adjustment knob for precise positioning.

Adjust joints at the top, middle, and bottom of the base to position the indicator in place. Use the knob on the fine-adjustment clamp to precisely angle the indicator. The base is magnetic and has a V-groove on the bottom for a solid mount on flat and curved metal surfaces. Flip a switch to release the magnet.

A spring-loaded plunger extends and retracts from the indicator to take measurements. The measurements display on an easy-to-read LCD display. Start measuring at any point by pressing the zero-set button. They have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the indicator is off.

All can send data to your computer using a USB cord (sold separately).

Adjust the flexible ball-and-socket segmented arm to nearly any position and lock in place. A heavy base adds stability.

Vise-grip locking pliers clamp this holder to most thin, flat surfaces, and the flexible arm lets you position your indicator around obstructions. Lock the arm in place with a lever.

Adjust the flexible arm to nearly any position. These holders have a ball-and-socket segmented arm that locks in place with a lever. The magnetic base has a release switch for easy setups.

Stick the magnetic base onto metal surfaces for a secure hold while measuring. They have a V-grooved bottom that stays secure on flat and curved surfaces. To precisely position the indicator, adjust the knobs on the arm and clamp.
