No foreign substances are mixed in, and it can be safely used in food-related equipment!
We would like to introduce a case study of the use of "SDC Clean Bolt" in the Safety Measures Management Department for Food Manufacturing Equipment. Since it is used in food manufacturing equipment, lubricants and plating cannot be used. If tightened repeatedly with the material (untreated) for cleaning, the stainless steel bolts can seize. The "SDC Plasma Surface Hardening Treatment" used in this product prevents seizing by hardening the material itself, unlike plating or coating, so there is no peeling of the hardened layer during fastening. There is no contamination with foreign substances, making it safe to use even in food-related equipment. 【Product Information】 ■ Material: SUS316(L), pure titanium, titanium alloy (6AI-4V) ■ Surface Treatment: SDC Plasma Surface Hardening Treatment ■ Shape: Hex bolts, hex nuts, hex socket bolts (cap screws), hex socket set screws (hollow sets), and other special shapes are also available ■ Features: Prevents galling and seizing while maintaining the corrosion resistance of stainless steel and titanium ■ Specifications: Processed with gas vent holes, precision cleaning, and special packaging for clean rooms *For more details, please download the PDF or feel free to contact us.

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. Please feel free to contact us for more information.*
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.
