Custom DIN934 Hex Nut

DIN934 Hex Nut Introduction: The DIN934 hex nut, also known as ISO4032 hex nut per the international standard, has two types: coarse thread and fine thread. By product grade, it is divided into grade A and grade B, the former used for specifications smaller than or equal to M16 and the latter used for specifications larger than M16. Hex nuts are usually used together with bolts and screws. The hex nuts with coarse threads are not as good as the hex nuts with fine threads in terms of either self-locking or checking but has better locking force. The hex nuts with fine threads are better at checking, suitable for vibration resistance and easy for gap control. They are applicable to the cases requiring gap or moment control. Normally, the hex nuts with fine threads are chosen unless there are special requirements. According to the DIN934-1987 standard released in Germany in 1987, the IN934 hex nuts refer to the hex nuts with product grades A (≤M16) and B (>M16) as well as thread specifications M1 – M60.

DIN934 hex nut materials: By material, DIN934 hex nuts are divided into three types: carbon steel hex nuts, stainless steel hex nuts, and nonferrous metal hex nuts. Strength grades of the carbon steel hex nuts: grade 6 for M2.5 and below, grade 8, grade 10, and negotiation required for M39 and above. The nuts of performance levels 4, 5, 6, 04 and 05 can be made of free cutting steel whose maximum contents of sulphur, phosphor and lead are 0.30%, 0.11% and 0.35%. For the nuts of performance levels 10 and 12, to improve their mechanical properties, alloying elements can be applied when necessary. Strength grades of the stainless steel hex nuts: A2-70, A4-70 or A4-80 for M39 and below, and negotiation required for M39. Note: If the content of chromium is less than 17%, the minimum content of nickel should be 12%. For the austenitic stainless steel with maximum content of carbon up to 0.03%, the content of nitrogen can be up to 0.22%. For the product with a larger diameter, to achieve special mechanical properties, a higher content of carbon may be specified on the manufacturer’s instructions but should be larger than 0.12% for austenitic steel. Performance levels of the nonferrous metal hex nuts: CU2, CU3, and AL4. The nonferrous metal hex nuts are rear in daily use, with just a brief introduction: the material designation is CuZu37 for CU2, CuZn39Pb3 for CU3, and AlCu4MgSi for AL4.

Application scope of the DIN934 Hex Nuts: The German standard DIN934 hex nuts are in wide application, usually together with bolts, studs and screws for fastened connection. Grade A (applicable to nominal thread diameter D≤16 mm) and grade B (applicable to D> 16 mm) nuts are used for machines, devices or structures with low surface roughness and high accuracy requirements. The DIN934 nuts feature large fastening force, and adjustable spanners, open spanners, and glasses spanners can be used for installation. All of the above spanners require large operation space. Since the fastening effect of a hex nut depends directly on its conformance to the standards, Yijin Hardware always stick to the principle of quality first while manufacturing both standard and nonstandard hex nuts. As a custom hex nut factory, Yijin Hardware has unique advantages and over 20 years of production experience. If you need DIN934 hex nuts or custom hex nuts, please believe that Yijin Hardware is capable of manufacturing quality products for you!
