Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.

A black-phosphate finish provides mild corrosion resistance.

The strongest key-locking inserts we offer, these inserts are made to stringent military specifications.

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

A black-phosphate finish provides mild corrosion resistance.

These assortments include various sizes of 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.

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

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

Stronger than stainless steel, these nuts are comparable in strength to Grade 9 bolts.

Vent air from your enclosure to equalize pressure and stop condensation from forming inside while securing cords in wet environments. These polyamide grips are lightweight and resist rusting.

Keep cords from coming loose and seal water out of enclosures in extremely cold labs and storage areas. Thanks to their plastic bushing and rubber O-ring, these grips withstand temperatures as low as -75° F.

Suitable for use in applications where cords are underwater—these grips are rated IP68 for protection from prolonged submersion.
