SA 194 Gr 8 Nylock Nuts and Sae J995 Grade 8 Hex Nut manufacturer in India

Jignesh Steel offer Annealing heat treatments for Grade 8 Nuts, which is available in different sizes and dimensions. It has great usage in different applications that are being used in different industries. Grade 8 Hex Nut is part of the SAE classification; it is the minimum standard of the structural and automotive industries and it is useful in high-temperature applications. Grade 8 Lock Nut has high chromium and nickel contents provide comparable corrosion resistance. It possesses higher elevated temperature oxidation and stress rupture, creep resistance, and tensile strength compared to other grades. Grade 8 Coupling Nut is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding. It is also called extension nuts it is used to join two threaded rods or pipes, including threaded rods or pipes of different sizes. It is commonly constructed in a hex shape for wrench hold, the most common uses for coupling nuts are tightening rod assemblies or to pushing a completed rod assembly outward. Grade 8 Nylock Nuts is also known as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut. It is a kind of locknut with a nylon collar that increases friction on the screw thread. SA 194 Gr 8 Flange Nuts have a flange at the bearing face that removes the need for a washer and spreads the surface loading. The underneath of the flange is normally plain but can have radial serrations that produce a locking action on the bearing surface. It is high temperature stainless steels which are primarily used at elevated temperatures to take advantage of its oxidation resistance. However, it is aqueous corrosion resistant due to its elevated chromium and nickel contents.
