Characteristics
- Hex socket head cap screws with small head diameter. Able to reduce the spot facing diameters compared to standard hex socket head cap screws.
- SUS316L is a stainless steel made by adding Mo to SUS304, so it has high pitting resistance and oxidation resistance. Due to its reduced carbon, it also has high intergranular corrosion resistance. This screw also has corrosion resistance against chemical products and seawater environments that matches or exceeds SUS304.
- Because the basic components include Mo, the strength is high even at high temperatures.
- Non-magnetic.

Application
FPD production equipment / Semiconductor manufacturing equipment / Offshore instruments / General industrial machinesUsage Example
It is possible to perform spot facing and hide the head in locations where spot facing is not possible with standard hex socket head cap screws.
Precautions for Use
- Since the head bearing surface area is small, the bearing surface pressure increases.
- Using the following formula as a reference, ensure that the bearing surface pressure due to screw tightening does not exceed the permitted surface pressure of the intended fastening material.
