Frequently Asked Questions

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

The 18-8 stainless steel construction resists corrosion, making it suitable for industrial applications where vibration or pressure could cause leaks.

What are the specifications of the USA INDUSTRIALS self-sealing hex head bolt?

This bolt is an 18-8 stainless steel sealing hex head cap screw with a 3/8"-16 thread size, 1-inch length, and plain finish. It is sold in a 5-pack with manufacturer part number ZBOLT-385. The self-sealing design incorporates a pre-applied sealant to prevent leakage in threaded joints.

How to install a self-sealing hex head bolt?

Install the self-sealing hex head bolt by threading it into a clean, dry tapped hole. Tighten to the manufacturer's recommended torque specification for 18-8 stainless steel fasteners.
