Nuts Hex nuts are used in conjunction with screws and bolts to connect parts. ASME ANSI hex nut covers the dimensional requirements of inch series hex nut. The common standard of ASME/ANSI hex nut is ASME B18.2.2. It includes normal hex nut, hex thin nut, hex thick nut and heavy hex nut. The size from 1/4-4" diameter. DIN standard is DIN934. Hex nut is widely used, mainly in the field of machinery and equipment, construction, automobile, railway and other industries. The mechanical property has grade 2, grade 5, grade 8 for inch series, grade 4, grade 8, grade 10, grade 12 for metric series. Jiangsu Jinrui metal products Co., Ltd. is one of the leading hex nut manufacturers and suppliers in China. Welcome to buy hex nuts from our factories and companies. Features and Advantages of Hex Nuts 1. The hex nuts produced by our company all use the raw materials from well-known steel mills, and corresponding material reports can be provided. 2. The size has wide range, such as from M3-M90. 3. The hex nuts is made of high-quality steel, it has high thread precision, It is very smooth when matched with the bolt. 4. Grade of hex nuts meets ISO standard, such as ISO898. Also our hex nuts has beautiful coating with good corrosion resistance. The toughness of the product covered with the coating will also be strengthened and will be more durable.
