APM HEXSEAL announces the availability of a full range of mechanical and liquid-applied threadlocking add-ons for their comprehensive line of re-usable high-pressure self-sealing screws, bolts and nuts.

Fully adjustable Nylon locking pellets and strips can now be added to the thread surface, precisely positioned (location & depth) to maximize anti-vibration dampening. These devices remain locked whether the fastener is seated or unseated. They are impervious to a wide range of chemicals, water and motor fluids and will not dry, shrink or loose resiliency when exposed to commercial solvents, alcohol, gasoline, caustic soda, etc. Reusable to +550ºF (288ºC) depending on locking material chosen. Also available is a patch dry coating process which is fused to selected threads delivered ready to install without the need for curing or other special preparations.
