ADJUSTABLE LOCKING PELLETS FOR SEELSKREW®, SEELBOLT® & SEELNUT® SELF-SEALING FASTENERS
FULLY ADJUSTABLE & REUSABLE PER IFI 124, IFI 524 & MIL-DTL-18240F, NASM25027
When assembled with a mating part the resilient engineered polymer pellet (normally Nylon) is compressed, and a locking action is established. APM Pellet Locking action takes place inside the threads due to its vibration dampening characteristics, as opposed to at the bearing surface. The resilience of the pellet holds the fastener in place without adhesives or thread distortion. The pellet’s resiliency also contributes to its superior degree of adjustability and repeated reusability.
Self-Sealing screws, bolts and nuts that have pellets installed can operate and deliver outstanding performance in both high and low temperature extremes without degradation. Under most operating conditions, these pellets are unaffected by vibration of reversal of stress. Installed in a drilled hole (just below the depth of the thread), APM pellets are typically positioned one to three threads back from the end of the fastener to assure ease of starting. Hole positioning can be modified to meet specific applications – contact Technical Sales for assistance.
