DIN 7991 Flat Head Socket Cap Screw

DIN 7991 Flat Head Socket Cap Screws are internally wrenched (hex socket) countersunk-style with external machine screw threads, a flat top and cone-shaped bearing surface. The head angle is 90° for M20 and smaller and 60° for M22 and larger (inch series screws are 82°). When mounted in a matching countersunk recess the top of their head will be flush with the mounting surface. Select from Class 10.9 zinc plated and plain finish (no rust protection) steel and stainless steel. Thread tolerance is 6g; right-hand threads are standard. NOTE: They are manufactured in Class 10.9 (and above) to increase wear resistance of the hex socket recess—head geometry reduces loadability and prevents them from being used in high-strength applications (see ISO 898-1). The length of flat head screws is measured from the top of the head to the tip. DIN 7991 Flat Head Socket Cap Screws are similar to ISO 10642 and ANSI B18.3.5M.

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.
