How to install a self-sealing hex head bolt?
Install a self-sealing hex head bolt by threading it into a clean, dry tapped hole or nut. Tighten to the manufacturer's recommended torque specification for the bolt size and material—typically using a torque wrench for accuracy. The sealing element (often a pre-applied patch or O-ring) compresses during installation to create a leak-resistant joint. Avoid over-tightening to prevent seal damage.
