LOCKING STRIP (BAR) FOR SEELSKREW® & SEELBOLT® SELF-SEALING FASTENERS
REUSABLE TO +550°F (288°C) PER IFI 124, IFI 524 & MIL-DTL-18240, VARIOUS NAS, AN, & MS CALLOUTS
A resilient engineered polymer bar (strip) is inserted into a precise slot that has been milled into the threads making the fastener selflocking as well as self-sealing, while remaining fully adjustable. The APM Strip delivers outstanding performance in both high and low temperature extremes.
When assembled with a mating part the resilient APM Strip (usually Nylon) is compressed which provides a locking action in the thread instead of at the bearing surface due to vibration dampening characteristics. The fastener is held in place without the use of adhesives or thread distortion. The result is a self-sealing reusable fastener that is both locking and repeatedly adjustable. APM Strips are typically positioned one to three threads back from the end of the fastener to assure ease of starting. Special strip positioning can be tailored to fit your needs – contact Technical Sales for assistance.
