Black-Phosphate Steel Key-Locking Inserts
A black-phosphate finish provides mild corrosion resistance. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. Use them to repair or change threads in soft metals such as aluminum. They’re comparable to Keensert® inserts. Installation requires a drill bit, a standard tap, an installation tool, and a hammer.
Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole with stripped threads.

Stainless Steel Helical Inserts
Also known as Heli-Coil inserts, these inserts have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.

Left-Hand Threaded Tube-End Weld Nuts
Use these tube-end nuts with left-hand threaded fasteners. You can weld them to round uncoated metal tubes to attach threaded parts, such as rod ends. Also known as tube adapters and weldable threaded tube ends.

Threaded Bumpers
Mount these bumpers on a threaded stud. All are reinforced with a steel core or 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. All of these bumpers can be used outdoors.
Bumpers with a hard rating withstand high levels of impact. Bumpers with a medium-soft rating offer a balance of cushioning and impact resistance.
Neoprene bumpers have good abrasion resistance.
Polyurethane bumpers have better abrasion resistance than neoprene bumpers. They won't become brittle and crack when exposed to ozone.
