There is a calculation method used when you want to know the length of the threaded part! Here are some frequently asked questions.

The length of the threaded section varies depending on the product and size. There is a calculation method used when you want to know the length of the threaded section. 【For hex bolts】 M(thread designation)x2+6 / For lengths of 130 or more: Mx2+12 / For lengths of 220 or more: Mx2+25 【For hex socket bolts (caps)】 Mx2+12 (caps are not related to length) (Example) For a half-thread hex bolt M10x60: 10x2+6=26, so the threaded section is approximately 26. *For more details, you can view the related links.
