DIN 6334 Hex Coupling Nut

DIN 6334 Hex Coupling Nuts are long hex nuts with internal machine screw threads. Their length is about three times their nominal size (denoted as ~3d); for example, an M8 coupling nut is 24 mm long. Used to couple two like-sized externally threaded fasteners, such as hanger bolts with threaded rod, they sometimes function as spacers and standoffs because of their long length. Both ends have right-hand threads and coarse pitch is standard. Available in Class 6 steel and stainless steel; steel is zinc plated. Thread tolerance for plated nuts is 6H. Measure Hex Coupling Nut length from end to end.

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.
