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.

Single-Size Air-Powered Rivet Nut Tools
Use compressed air to install rivet nuts with less effort than manual tools. Tailored to specific thread sizes, these tools rotate a rivet nut with the exact force needed to collapse it onto your workpiece. They’re smaller and lighter than other powered rivet nut tools, so you can squeeze them into tighter spaces. However, they generate less force, so they’re not recommended for installing nuts into thick materials.
Angle grip tools fit into tighter spaces than pistol grip tools.

Air-Powered Rivet Nut Tools
Install any size or style of rivet nut with a single tool. When you connect these tools to your compressed air line, the hydraulic fluid inside is pressurized, which generates the force needed to collapse a rivet nut. They’re also known as hydropneumatic rivet nut tools. Rather than rotating the rivet nut, like single-size rivet nut tools, these tools pull it straight back. This means you can adjust the pull force or stroke depth to match your application. Set the pull force if you’re installing rivet nuts into workpieces with different thicknesses. Set the stroke depth to install rivet nuts in soft or fragile materials without cracking or warping the surface.
Use tools with a 7,190 lb. pulling force to install rivet nuts made from hard materials, such as titanium. They’re also good for large nut sizes. However, they take about three times longer to install a nut than tools with a 3,960 lb. pulling force.

Pull Force Calibrators for Rivet Nut Tools
Avoid failed rivet nuts by periodically testing the pull force of your rivet nut tool. These calibrators work with air-powered and hydraulic/air-powered rivet nut tools. They display force measurements on two digital touch screens. The left screen shows a graph and read-out of current pulling force, while the right screen shows the results of the last seven tests. Track performance to plan maintenance—they store test data on the included microSD card.
An anvil and mandrel assembly (sold separately) is required. Choose a thread size that matches your tool. Thread the anvil and mandrel assembly onto the calibrator to begin testing.

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.

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.

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.

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.
