For high-strength fastening
Thread inserts create load-bearing joints in metal materials with low shear strength.
Thread inserts have been proven in practice. For over 65 years. They are available in Free Running and Screwlock versions. The silver or red color simplifies identification even when installed.
Product Benefits
True quality appears under extreme conditions. Even when exposed to high temperatures and humidity, thread inserts remain stable and reliable. Depending on the application, the thread inserts are made of different materials.
Long-lasting. The high surface quality of the rolled thread made of austenitic chrome-nickel steel ensures a high-strength, wear-resistant thread with a constant, extremely low thread friction torque.
Uniform along the entire length of the screw. The elastic properties of the thread insert allow uniform load and stress distribution.
No self-loosening. The thread technology and polygonal twist of the Screwlock result in a high degree of frictional connection and therefore in a screw lock. Additional locking of the joint using split pins, wires or washers is not necessary.
Less friction, more precision. For a torque-controlled screw tightening application, the screw pre-load force can be adjusted more precisely and the yield point of the screw utilised more efficiently.
Perfect for lightweight construction. Threaded inserts combine minimum space requirements and high strength. Thus, high-strength screws are also perfect for use in materials with low shear strength.
