What is a self-sealing hex head bolt used for?

A self-sealing hex head bolt is used to create a leak-proof joint in fluid-handling systems such as pumps, hydraulics, and pneumatics. The 18-8 stainless steel construction resists corrosion, making it suitable for industrial environments where vibration or pressure could cause standard fasteners to leak.

How to install a self-sealing hex head bolt?

Install a self-sealing hex head bolt by threading it into a tapped hole or nut until the sealing element compresses against the mating surface. Use a torque wrench to tighten to the manufacturer's recommended specification, avoiding over-torque that could damage the seal. Ensure threads are clean and lubricated if required.
