APM SEELSKREW®
Reusable, High-Pressure Self-Sealing Screws

The APM SEELSKREW® is the original self-sealing screw designed and patented by APM. SEELSKREWs are designed to seal out air, water, lubricants and other liquid or gaseous contaminants. They are available in many standard thread sizes and with optional sealing materials. When viration is an issue, SEELSKREWs can also be supplied with either self-locking pellets, strips or patches, Black oxide, painted heads, or in a captivated (KAPTO-SKREW®) configuration. Sheet metal and other type fasteners available on special order.

SEELSKREWs are pre-assembled to 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, they can withstand internal and external pressures/vacuum to 20,000+ psi.
