Micro fasteners with infinite possibilities.
The micro fasteners (precision screws for precision equipment) we offer can be produced using a cold forging method, allowing for the cost-effective mass production of precision screws in sizes ranging from M0.6 to M2.6.
Mill sheets and inspection certificates are also available! Prevents nuts and bolt heads from sinking into the joined materials.
We would like to introduce the "Flat Washer 300HV" handled by Sanwa Ai. It prevents the nut or bolt head from sinking into the joined material. When the hole diameter is larger than the bolt diameter, it can be used to stabilize the seating surface. Additionally, it has undergone quenching and tempering heat treatment. Please feel free to contact us when you need it. 【Features】 ■ JIS B 1256:2008 ■ Recommended combination with screw part strength classification 10.9 (JIS B 1061:2020) ■ Material: S45C to S55C (domestic material) ■ Marked with hardness classification 300HV ■ Mill sheet and inspection certificate available *For more details, please refer to the PDF document or feel free to contact us.
