DIN 912 Socket Head Cap Screws

DIN 912 Socket Head Cap Screw

DIN 912 Socket Head Cap Screws have a small diameter cylindrical head, a hex socket recess and external machine screw threads; the side of the head may be plain or knurled. Internal wrenching allows for close screw spacing and the head can be recessed in a counterbored hole. Unlike inch series screws, which are available in a single strength grade, steel metric socket head cap screws are available in three grades: Class 8.8, 10.9 and 12.9. There may also be three grades in stainless steel: Class 50, 70 and 80; most are Class 70 (A2-70, A4-70) and some are Class 80 (A4-80), but unusual sizes could be Class 50. Consequently, check the head marking and replace metric socket head cap screws with the same Class. Available in zinc plated and plain finish (unplated) steel, stainless steel and nylon; A2 stainless steel compares to 18-8 and A4 to 316. Thread tolerance is 5g6g for Class 12.9 and 6g for Class 8.8 and 10.9 and stainless steel; right-hand threads are standard. Measure length from under the head to the tip. DIN 912 Socket Head Cap Screws are similar to ISO 4762 and ANSI B18.3.1M. DIN 7980 High Collar Split Lock Washers and DIN 433 Small Pattern Flat Washers are small OD (outside diameter) washers that are used with socket head cap screws.

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.
