USA INDUSTRIALS Self-Sealing Hex Head Bolt: Stainless Steel, 18-8, Plain, 3/8"-16 Thread Size

A self-sealing hex head bolt is used in applications requiring a leak-proof seal, such as fluid handling, hydraulic systems, and pressurized equipment. The 18-8 stainless steel construction resists corrosion, making it suitable for industrial environments where vibration or thermal cycling could loosen standard fasteners.

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.
