MORE ABOUT SELF-SEALING FASTENERS FROM APM:
SCREWS, BOLTS, NUTS AND WASHERS
APM's patented, pre-assembled self-sealing screws and fasteners provide both fastening and sealing integrity in a single unit. Unique design features a resilient silicone O-ring held captive in a precision engineered groove under the head. Vibration-resistant and reusable screws, bolts and nuts withstand internal and external pressures/vacuum to 20,000+ psi. When vibration is an issue, APM offers a full line of self-locking add-ons (pellets, strips, patches). SEELOC® Washers are vibration-resistant, self-sealing washers, each having a silicone rubber section, molded and bonded to a stainless steel formed washer ideal for large or slotted holes.
