A4L-100 SUS316L high-strength stainless steel bolt

A4L-100 SUS316L high-strength stainless steel bolt

A4L-100 is a high-strength stainless steel bolt. It is available in a lineup from M16 to M27.

Based on years of experience using various types of stainless steel, SUS316L is highly regarded for its corrosion resistance and non-magnetic properties, and it is widely available in the market. We have developed bolts with a tensile strength of 1,000 N/mm² using SUS316L, along with nuts and washers designed to be used in combination with these bolts. In the development process, we focused on three points: 1. simplifying the manufacturing process, 2. preventing galling (deterioration of torque coefficient) caused by metal contact between the bolt and nut when tightened with high axial force, and 3. ensuring that the nuts and washers, which can withstand the strength of the bolts, are made from the same material.

[Usage Example] Food Manufacturing Equipment Safety Measures Management Department

[Usage Example] Food Manufacturing Equipment Safety Measures Management Department

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.
