USA INDUSTRIALS Self-Sealing Hex Head Bolt: Stainless Steel, 18-8, Plain, 1/2"-13 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 provides corrosion resistance, making it suitable for industrial environments where vibration or thermal cycling could loosen standard fasteners.

This USA INDUSTRIALS bolt is an 18-8 stainless steel sealing hex head cap screw with a 1/2"-13 thread size, 1-inch length, and plain finish. It is sold in a 5-pack with manufacturer part number ZBOLT-391. The self-sealing design incorporates a pre-applied sealant to prevent leaks without additional washers.

Installation is similar to a standard hex head bolt: clean the threaded hole, apply the bolt by hand to avoid cross-threading, then torque to the manufacturer's specification. The pre-applied sealant activates upon tightening, so avoid over-torquing. For critical applications, verify compatibility with the fluid or pressure rating.
