Low-Profile Setup Clamps with Threaded Hole


Designed to provide more clearance above the nut than standard clamps, these have an offset shape. Instead of a step block, support them using a screw, leveling mount, or any other threaded object. Pair with a T-slot nut or bolt to secure a workpiece, vise, or fixture to a machine table. Also known as gooseneck clamps.

Low-Profile Setup Clamps


The offset shape provides more clearance above the nut than standard clamps. Use with T-slot nuts or bolts and a support to secure a workpiece, vise, or fixture to a machine table. Clamps can be supported with step blocks or any flat object. Also known as gooseneck clamps.

Dual-Clamping Low-Profile Setup Clamps


Position these clamps between two workpieces, vises, or fixtures and secure both to your machine table using T-slot nuts or bolts. Their low-profile shape provides more clearance for cutting tools above them than standard clamps.

Spring Clamps with Flexible Arm




Attached to an arm you can flex into position, these clamps hold objects such as a flashlight, tool, or instructions. Squeeze the handles to open the clamp; release and the spring holds it tightly in place.
Magnetic-mount clamp attaches to steel surfaces.

Bend-and-Stay Positioning Arms
Stronger and with greater load capacities than gooseneck-style positioning arms, these arms keep their shape even when moving or when exposed to vibration. They’re often used in robotics and conveyor applications when frequent repositioning isn’t required.
All accessories include the necessary hardware for attaching them to arms.
Clamp-on bases have two arm attachment locations. Place arms straight or at a right angle from the clamping screw. Clamp-on bases with a rubber V-block can be mounted to rounded surfaces such as pipe and railings.
Spring clamps with three attaching end mounting holes can be mounted parallel or perpendicular to your positioning arm. Spring clamps with a 4 1/2" reach clamp further into a workpiece than other spring clamps.
Three-finger clamps have bent fingers to hold workpieces that are hard to grip, such as beakers, flashlights, and webcams. A rotating position lock lets you rotate these clamps on your positioning arm. Secure clamps in place with the included locknut.

Economy Dial Plunger-Style Variance Indicators with Clamp-On Holder



Often used where space is tight or there’s not much of a surface for mounting, the clamp on these indicators fits where a weighted or magnetic base can’t. The clamp also gives you the option to directly mount these indicators to a machine or the piece you’re measuring. With the ball-and-socket segmented arm, you can adjust the indicator to nearly any position to keep it from obstructing what you're measuring. Pull the lever to lock the arm in place when you're done. To measure objects, these indicators have a spring-loaded plunger that retracts and extends as the surface varies. It’s easy to see how much a measurement increases, since the dial is continuous and numbered clockwise around the face. Adjust the tolerance pointers to mark measurements that fall outside your limits.
Indicators with a plier clamp work on most thin, flat surfaces.
Indicators with a C-clamp apply less pressure than indicators with a plier clamp, so there’s less risk of damaging a workpiece.

Economy Electronic Plunger-Style Variance Indicators
with Magnetic-Base Holder for Uneven Surfaces
With adjustable magnetic pins that conform to any shape, the base on these variance indicators mounts securely to uneven surfaces. The ball-and-socket arm is highly adjustable and locks in place with a lever, so it holds the indicator in almost any position. For quick dismounting, the base has a magnetic release switch.
A spring-loaded plunger extends and retracts to measure objects. The measurements are displayed on an LCD screen. 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). They have SPC data output to wirelessly transfer your measurement data to your device with the push of a button. You'll need a data transmitter/receiver set (sold separately). Indicators with Bluetooth send measurement data to your device wire-free and without an additional device.
IP67-rated indicators seal out coolant, water, and dust, so you can take measurements in dirty machining environments.
Tolerance checking indicators inform you when an item falls outside your set measurements.

Arms for smartphones have spring-loaded brackets to grip the outside of your smartphone while leaving the screen visible.
Arms for irregularly-shaped devices hold mobile devices that don’t have a uniform shape, such as radios and GPS navigators. They have rubber fingers that adjust to fit around curves, avoid antennas, and grip asymmetrical devices.
Clamp-on rectangular bar-mount arms have a base that fits around rectangular parts, such as square posts, t-slotted framing, and rails.
Clamp-on pipe-mount arms attach to round bars, pipes, and railings using adjustable jaws. They’re commonly used to mount screens to cart handles.

Tablet Positioning Arms
Position your tablet within view while keeping your hands free to work. These arms mount to a variety of surfaces while keeping a secure grip on your tablet.
Clamp-on bench-mount arms attach to the edge of a workbench or tabletop. They have two pivot points that rotate 360°. The joint behind the tablet holder allows you to rotate the screen and tilt it for a better viewing angle. No need to lock them in place—the pivot points stay in position on their own.
Bar-, pipe-, magnetic-, suction-, and threaded-stud-mount arms have ball-and-socket joints that give them a 360° range of motion. Tilt or rotate them for a better viewing angle and lock the joints in place.
Clamp-on rectangular bar-mount arms have a base that fits around rectangular parts, such as square posts, t-slotted framing, and shelving units.
Clamp-on pipe-mount arms attach to round bars, pipes, and railings using adjustable jaws. They’re commonly used to mount screens to cart handles.

Vibration-Resistant Tablet Positioning Arms
These arms lock around the top and bottom edges of tablets to keep them from shaking loose in areas with strong vibrations. They’re often used to mount tablets onto forklifts and other machines. Their ball-and-socket joints rotate 360°, so you can move these arms in any direction, then lock them in place.
Rectangular-bar mount arms fit onto square posts and rails, which are often found in forklift cages.
Pipe mount arms clamp onto cart handles, railings, and other round supports.

Monitor and Keyboard Positioning Arms

Your entire workstation mounted on a single arm. These arms have two plates, each with its own industry-standard mounting pattern. Connect monitors, tablets, keyboards, and other compatible devices to them. Swing your keyboard out of the way or tilt your monitor for a better view—these arms have ball-and-socket joints for 360° range of motion. To keep a configuration, simply lock the joints in place.
VESA (Video Electronics Standards Association) mounting hole patterns attach to monitors. AMPS mounting hole patterns attach to keyboards. To connect two devices with VESA mounting hole patterns, use adapters (sold separately) to convert the AMPS end mount to a VESA end mount.
Rectangular bar-mount arms have a base that clamps around rectangular parts, such as square posts, t-slotted framing, and rails. They’re commonly used on forklift cages.

Pipe- and Bar-Mount Monitor Positioning Arms




Mount monitors to round and square bars, such as equipment handles and support beams. These arms have a VESA standard mounting hole pattern to attach monitors, tablet holders, and other compatible devices. Tilt your screen for a better view or raise it to eye level—ball-and-socket joints give these arms 360° range of motion.
Clamp-on pipe-mount arms have jaws at their base that grip round bars, pipes, and railings. These are often used to mount screens to cart handles.
Clamp-on rectangular-bar-mount arms have plates that clamp to rectangular parts for a secure hold. Use them with square posts, T-slotted framing, and shelving units. These arms have an additional AMPS standard mounting hole pattern, which is commonly used to attach tablet holders and keyboards.
