DIN 934 Hex Nut

DIN 934 Hex Nuts, with their internal machine screw threads, are the most common type of nut in use and are mated with virtually all externally threaded fasteners that have machine screw threads. Their nominal (maximum) thickness is about 0.8 times their nominal size (denoted as ~0.8d), so an M10 hex nut has a thickness of 8 mm. Class 6, 8 and 10 steel, and Class 50 (uncommon sizes), Class 70 (A2-70, A4-70), Class 80 (A4-80) stainless steel hex nuts are available. A2 stainless steel is comparable to 18-8 and A4 is equivalent to 316. Coarse threads are standard, but some are available with fine and extra fine threads; right-hand threads are typical. Plain finish, which lacks a rust inhibiting surface treatment, and zinc plated are common finishes for steel. Thread tolerance is 6H for plain finish and plated steel and stainless steel. The strength grade (Class) of the nut should always be equal to or greater than that of the screw. DIN 934 Hex Nuts are similar to ISO 4032, Style 1; JIS B1181; and ANSI B18.2.4.1M, Style 1. If you need a thin (reduced height) nut and can tolerate reduced strength, consider DIN 439 B.

Product Filter Help

It's easy and fast to find the exact item you're looking for using these filters. Depending on the item, you can filter by Size (diameter and thread), Length, Grade/Class, Material and Finish/Plating. Here's how…

  • Click in a Select box to view the options. It may be necessary to scroll to see the entire list. The number of matching items is displayed in parentheses ( ).
  • Click on the desired item and -- Select -- will change to 1 Selected. You can select more than one item in each Select box. For example, you can select two sizes and 1 Selected will change to 2 Selected.
  • Click in other Select boxes and make more choices. Available options will be based on selections you've already made.
  • Even though there are thousands of fasteners to choose from a particular material or finish may not be available in every size and length. So, try different combinations of filters like Size, Grade and Material to see matching Lengths and Finishes.
  • To deselect a single filter option, click in the Select box and click on the selected option. It will appear at the top of the list in bold. To clear all filter selections, click on the Clear Filters button.

Even after filtering there may be several pages of items. The number of pages will be displayed to the left of the Add All Selected Items button. Click on a page number or the arrows to page forward and back.
