No adhesive needed for increased productivity! Screw technology that demonstrates excellent effectiveness in preventing loosening!
Conventional screws have issues such as "screws loosening over time in thin plates or areas with a low number of effective threads," "in areas where adhesives are used to prevent loosening, the effectiveness of the adhesive decreases over time, making repeated use impossible," and "with screws that incorporate washers, screws loosen over time." Matsumoto Sangyo's Noji Lock Screw locks loosening at each thread! Therefore, it is fine even if the number of effective threads on the female side is low. Additionally, due to the anti-loosening technology (Noji Lock) on the male thread side, there is no need to choose the shape of the female thread. It is ideal for applications such as micro medical devices, glasses and sunglasses, mobile phones, digital cameras, laptops, small hard drives, and micro motors. ★If you would like a sample, please contact us!★
