ISO 2338 Dowel Pin

ISO 2338 Dowel Pins, referred to as parallel pins, are headless solid cylindrical pins manufactured to a precise diameter. Used to align parts and function as hinge and wrist pins, roller bearings or as shafts, one end is chamfered (~15°) to facilitate insertion while the opposite end may be radiused or dimpled. For press-fit applications, dowel pins should be pressed into position—do not use impact force because pin splintering may occur. Tolerance Class m6, oversized, and undersized h8 are available in plain finish unhardened steel, which can rust, and stainless steel. The "limit deviations" (or "tolerance zone") varies by diameter; for example, the tolerance of an M4 m6 pin is +0.004 to +0.012 mm while the diameter of an M4 h8 pin is 0 to -0.018 mm. Length is measured from end to end including the chamfer like DIN 6325 and inch series dowel pins but unlike DIN 7, which is not measured from end to end. ISO 2338 Dowel Pins may be similar to DIN 7.

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.
