Strengthening Book of Screws (Vol. 9) Differentiation of Hex Socket Bolts

Introducing the different uses of hexagon socket bolts in a blog format!

For bolts with hexagonal holes, we will consider the so-called standard hexagon socket bolts as the reference. Although it is slight, using hexagon socket button bolts with a larger head diameter can stabilize the seating surface, which is the contact area between the screw and the counterpart material, and alleviate the sinking (dimpling) into the counterpart material. However, it seems that button bolts are often used to create a neat appearance in the visible parts of the fastening section. *For more details, you can view the related links on the blog.

Strengthening Manual for Screws (Vol. 14) Standard Products and Supplementary Products

Introducing the differences between standard products and supplementary products in a blog format!

What is the difference between standard products and supplementary products? In the case of hex bolts, the dimensions differ in some sizes. For M10, the width of the hex head (also known as the distance across flats or the width across two sides) is 16 millimeters for standard products and 17 millimeters for supplementary products, which is a difference of just 1 millimeter. Just 1 millimeter. Of course, those who use hex bolts may not think much of it. A difference of 1 millimeter means you need to change the tool for tightening and loosening. *You can view the detailed content of the blog through the related links.

Hexagon socket bolt (cap)

Improved reliability and workability by preventing loosening with high clamping force.

Hexagon socket bolts (caps) are generally used without being paired with nuts, so referring to them as screws is more accurate. However, since the name hexagon socket bolt has become widespread, they are also called cap bolts. The applicable strength grades are 8.8, 10.9, and 12.9. They are tightened with a hexagon rod wrench (with a maximum shank length of 1,000 mm). *In urgent or emergency cases, please direct any technical inquiries through our website.
