Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

Also known as trapezoidal-thread lead screws and nuts.

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start metric ball screws and nuts, these have a single thread that runs the length of the screw.

Stainless steel nuts have excellent corrosion resistance in most environments.

Made of 18-8 stainless steel, these inserts have good corrosion resistance.

Forming the strongest hold of any of our threaded inserts, these inserts have a distorted internal thread to lock screws into place and keys that drive into surrounding material to prevent slipping and rotating.

These inserts come with an installation tool. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts.

Made of Nitronic 60 stainless steel, these inserts prevent the screw from binding or sticking without any coating or lubricant that could contaminate particle-free environments.

Inserts come with a through-hole tap and installation tool.

Without a prong to break off and retrieve, these inserts are often used where debris could cause damage.

Made of 18-8 stainless steel, these inserts have better corrosion resistance than black-phosphate steel.

These assortments include various sizes of thread-locking inserts.

All of these bumpers are reinforced with a steel core for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines. Twist them into a threaded hole.

Select these bumpers for applications that require specific load capacities. All are reinforced with a base plate for strength. Often used as feet, spacers, and vibration dampers, they absorb shock to prevent damage to equipment and surfaces. They're also good for starting and stopping motion on automated machines and conveyors. Mount these bumpers on a threaded stud.
