Nuts

Nuts are used in electronics production, for example, together with screws or threaded bolts to mount circuit boards in an enclosure. With their internal threads, they are the counterpart to the screws or spacers. Most nuts have a right-hand thread; however, in certain cases, nuts with a left-hand thread or reverse thread are used.

There are numerous applications for nuts, including in the mechanical engineering and automotive industries, amongst many others. Assembly is often automated in series production; however, it can also be done by hand. The most common types of nuts are hex nuts because they can be fastened using a standard wrench. Square nuts are often used in electrical engineering or enclosure construction, among other things, and are fastened with hexagonal screws.

The type of nuts required depends on safety considerations, weather conditions, and other technical requirements. They are mostly manufactured in high quantities using a cold-forming process. Certain types of nuts are also produced using hot forging, turn milling or thread rolling processes. ETTINGER manufactures customized nuts from drawings, even in small quantities, using CNC-controlled precision turning machines in order to achieve high quality requirements and international standards. Depending on the customer's requirements and application, a surface coating can be applied to ensure better durability, e.g. an electroplated coating for corrosion protection.

You can buy nuts with the following thread types in the ETTINGER online shop:

• Metric threads to DIN and ISO
  
• UNC threads
• Fine threads
  

Most of our nuts in thread sizes M1.6, M2, M2.5, M3, M3.5, M4, M5, M6, M7, M8, M10, M12, M16 and M18 and with a Width Across Flats of 4 to 24 are made of steel. We also supply nuts made of brass and plastic.

Steel nuts are divided into different strength grades using the numbers 4.6, 8.8 and 12.9. This makes it very easy to determine their tensile strength (first number; 4.6) and yield strength (second number; 4.6).

For use in corrosive environments, stainless steel is also worth considering in addition to brass and plastic. The most commonly used stainless steel grades for nuts are A2 and A4. The A stands for austenitic steels, which have excellent ductility, resilience, and corrosion resistance. The number indicates the type of steel. A2 is used as standard, whereas A4 stainless steel nuts are used, for example, in coastal regions because of the high salt content in the air. A4 nuts are also used in areas near chlorinated water (which contains acid) and in the food and chemicals industries. Order you chosen version easily online, even in high quantities!

In contrast to stainless steel nuts, a protective coating (e. g. galvanized steel) is required on normal steel nuts if they are used in corrosive conditions. We offer different surface treatment finishing processes.
