In addition to fastening, our self-sealing screws and bolts offer a reliable and reusable seal, preventing (or containing!) contamination from dust, air, water, lubricants and other liquid or gaseous substances. They are also vibration resistant, making them a great choice for applications that encounter day-to-day jarring, or repetitive movement.
Should you need a more serious level of vibration resistance, our screws and bolts are available with additional locking features, such as self-locking pellets, strips and patches. Seelskrews® and Seelbolts® are available in many standard thread sizes and with various o-ring elastomer options. Some additional customizations include specialty thread-forming variations, tamper-resistant drives, thread captivation, as well as paint and finish options.
