APM Hexseal’s High-Pressure Self-Sealing Fasteners
APM Hexseal holds the notable distinction of having designed and patented the very first self-sealing fasteners, which became our trademarked Seelskrews® and Seelbolts®. 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 locking features such as self-locking pellets, strips and patches. Some additional customization’s include specialty thread-forming variations, tamper-resistant drives, thread captivation, as well as paint and finish options.
