How to install a self-sealing hex head bolt?
Install a self-sealing hex head bolt by cleaning the threaded hole and applying moderate torque with a standard socket wrench. The pre-applied sealant or O-ring on the bolt compresses during tightening to create a leak-proof joint. Avoid over-torquing, which can damage the seal. Follow manufacturer torque specifications for your application.
