A286 Hex Nuts
Given the requirements of heavy hex nut applications, the production units utilize the best of technologies, tools, and practices to manufacture the high-grade products. TorqBolt Inc. shares this similar notion and underlines the need for premium-quality production for the superior performance of the products, especially for a long-term period. We stock the Alloy A286 Hex Nuts required for applications in the high-temperature environments. As an ISO certified supplier, we pay utmost attention to the size, shape, and several required standard specifications. Alloy A286 emerges as an ideal material for fastener applications due to various attributes, but not limited to excellent fabrication characteristics, good corrosion resistance, oxidation resistance, and creep resistance.

A286 Flange Nuts
A286 flange nuts have excellent resistance to chemicals and salt water. With more points of contact than a hex, they allow you to get a better grip for more driver torque. The flange distributes pressure where the nut meets the material surface, eliminating the need for a separate washer.A286 Inch Flange Nuts
