How to install a self-sealing hex head bolt?

To install a self-sealing hex head bolt, clean the mating surfaces and apply moderate torque with a hex socket. The pre-applied sealant under the head compresses to form a leak-proof seal. Avoid over-tightening, which can damage the seal. Always follow the manufacturer's torque specifications for the application.
