Helicoil Nitronic Screw Thread Inserts, Helicoil Thread Repair Kits


About Helicoil Screw Thread Inserts:


Helicoil (also known as Heli-serts/Heliserts) inserts are available in free running and screw-lock forms and they come in a comprehensive range of lengths, materials, and platings. They provide the hole with smooth free running threads when installed.


Helicoil screw thread inserts are precision formed screw thread coils worked into a diamond shape. This wire is then wound into a spiral coil which when installed into Helicoil tapped holes, provides a permanent conventional 60 deg internal screw threads. Helicoil screw thread inserts provide a positive means for protecting and strengthening tapped threads in any material.


Helicoil wire thread inserts have an extensive background of tension, torque, shear, vibration and fatigue tests conducted by American industrys leading companies as well as the U.S. Military.

Successful applications in the fields of aviation, electronics, industrial, automotive and military equipment provide a wealth of experience and confidence in the performance and reliability of Helicoil wire thread inserts.

Keensert Keylocking Inserts, Keysert Keylocking Inserts, Tridair, Acme

About Keensert and Keysert Key-Locking Inserts


Keensert and Keysert Key-Locking Inserts provide high strength

and reliability and are designed to provide high resistance to

rotation and pull-out loads. After installation into the tapped hole,

the locking keys on each Keensert/Keysert are driven down

through the threads of the parent material, locking the insert

firmly and permanently in place.



Keensert/Keysert Keylocking Insert Features


- Can be used in virtually any material including aluminum, cast

iron, steel, and plastics

- Positive mechanical lock against rotation

- High strength and flexibility provides maximum pull out strength

- Easy installation and removal, can be installed using standard

drills and taps. However, Keensert installation kits are also

available if needed

installation in thin walled parts and hollow profiles, Bollhoff 
Rivnuts also permit blind riveting, combinations of riveting 
and screwing together of different parts, as well as spray 
water-tight sealed screw connections. 
Bollhoff Rivkle Blind Rivet Rivnuts Features
- Most versatile solution for adding a load carrying internal or 
external thread to thin-walled workpieces 
- Are often the only fastener solution for hollow sections, 
housings or where access is limited to one side of a component 
- No preparation is required for installation other than to drill or 
pierce a hole in the components to be riveted 
- No additional finishing required after setting, even with 
coated or painted components


Bollhoff Rivkle Blind Rivet Rivnuts Applications
- Cars and motorcycles, bumpers, safety belts, airbags
