JIS B1180 Small Head Hex Bolt

JIS B1180 Small Head Hex Bolts have the smallest width heads of all metric hex bolts/hex head cap screws. The width across flats (wrench size) of the three available sizes is 1 to 3 mm smaller than equal sized DIN 931, ISO 4014 and ANSI B18.2.3.1M bolts, while their head height is slightly larger. Otherwise, like their counterparts, they are partially threaded (PT) or fully threaded (FT) with external machine screw threads; use with both internally threaded holes and nuts. M8 is coarse pitch (1.25 mm) while M10 and M12 are fine pitch (but also 1.25 mm). Supplied in Class 8.8 steel, most are zinc plated to resist the formation of corrosion. Minimum threaded length of partially threaded bolts is related to bolt diameter; fully threaded bolts are also called tap bolts; thread tolerance is 6h for plated and 6g for unplated (plain finish); and threading is standard right-hand. Length is measured from under the head to the tip of the bolt.

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.
