Retention Knobs
Attach tool holders such as collet chucks and end mill holders to your CNC machine’s spindle. For proper operation, choose a knob that exactly matches your collet type and spindle dimensions. All meet industrial standards for tensile and shear strength. These knobs are also known as pull studs.
Knobs with a coolant hole let coolant flow through to protect your tools and workpiece.

Twist-Resistant Rivet Nut Assortments
Everything you need to add threads to sheet metal, these assortments contain twist-resistant rivet nuts, mandrels, nosepieces, and a plier-style installation tool. The nuts have a ribbed body that grips surrounding material to hold them in place, keeping them from spinning as you tighten screws. They create reusable threads in surfaces that are too thin to be tapped. Also known as blind inserts, installation requires access to just one side of your material. The flange distributes the load and holds the nuts against the surface. All are steel with a zinc yellow-chromate plating to resist corrosion in wet environments.
To install, thread a rivet nut onto the mandrel, insert the nut into a drilled or punched round hole, and squeeze the handles to secure the nut.

Rivet Nut Assortments
These rivet nuts have a smooth body and fit in smaller holes than twist-resistant rivet nuts. Assortments include rivet nuts, mandrels, nosepieces, and a plier-style installation tool. To install, thread the rivet nut onto the mandrel, insert the nut into a drilled hole, and squeeze the handles to secure the nut.
Aluminum rivet nuts are one-third the weight of steel rivet nuts and resist corrosion in wet environments.
Zinc-plated steel rivet nuts resist corrosion in wet environments.

Low-Profile Rivet Nut Assortments
Use these rivet nuts for light duty fastening in low-clearance applications. Assortments include rivet nuts, mandrels, and an installation tool. Rivet nuts have a cadmium plating that provides corrosion resistance and adds lubricity so they collapse smoothly. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut.

Steel Low-Profile Rivet Nuts with Installation Tool
Everything you need to add threads to sheet metal in low-clearance areas. Along with low-profile rivet nuts, these kits include mandrels and an installation tool. As you install these nuts, the threaded portion is drawn into the sleeve, reducing how far they stick out the back of your material. They also have a flange that’s half as thick as those on other rivet nuts, so they have a low profile on both sides of your panel. A tin-zinc plating protects from rust in wet environments and reduces friction, so they collapse smoothly. These rivet nuts create permanent threads in surfaces that are too thin to be tapped. Installation requires access to just one side of your material. The flange distributes the load and holds them against the surface.
To install, thread a rivet nut onto the mandrel, insert the nut into a drilled or punched round hole, push down on the tool's T-handle, and turn clockwise.

Air-Powered Rivet Nut Tools
Smaller and lighter than cordless and hydraulic rivet nut tools, use these to install thin-walled bulbed, ribbed, sleeve, and smooth rivet nuts. To use, thread the nut onto the included mandrel and press the trigger to spin the nut onto the tool. Place the nut into the material and press the trigger to install the nut. Press the trigger one more time to spin the mandrel off.

Inside Diameter Fixture Clamps for Castings and Rough Parts
These clamps wedge against the workpiece ID to grip cast, unfinished, or uneven parts, leaving the outside clear for machining. Do not use these clamps on smooth or finished ID’s because they will leave a mark. The clamp’s screw tightens from the top of the clamp, so workpieces require a through hole. Thread the clamp into a tapped hole in your fixture and place your workpiece over it. Reach through the hole to turn the screw, expanding the clamp.
