How to install a self-sealing hex head bolt?

Install a self-sealing hex head bolt by threading it into a clean, dry hole until the sealing element contacts the mating surface. Tighten to the manufacturer's recommended torque—typically moderate, not over-torqued—to compress the seal without damaging it. Avoid reusing bolts once the seal is compressed.
