Inconel 718 Outer Hex Bolt Fasteners

Inconel 718 outer hex bolt fasteners are made from nickel-based alloys known for their oxidation- and corrosion-resistant properties that allow them to perform well in high heat and high pressure environments. These corrosion resistant fasteners retain their strength and shape over a wide temperature range and do not exhibit the creep that aluminum and steel products do during temperature changes.
Wisine fasteners offers custom Inconel® 718 fasteners. Our staff specializes in working with non-standard materials and has the experience to accommodate the specific properties of specialty and hard-to-machine materials, ensuring that your fastener that will meet your exact application requirements and maintain its corrosion resistant properties. We offer full CNC machining and forging production facilities, and can manufacture your fastener to exacting tolerances with custom sizes, shapes and thread configurations
