How do you compare the APM One-Step Embedded O-Ring Self-Sealing Fastener System to the concept of just adding an O-Ring or washer to a standard screw or bolt?
When using just an O-Ring or deformable washer (regardless of material) as a pressure sealer you sacrifice the ability to fully clamp, plus the degree of thread sealing is not predictable. That’s because the O-Ring or washer interferes with achieving 360 metal-to-metal contact between the underside of the head and mounting surface. See Comparison Illustrations.
