screw
It is a rust-resistant stainless steel screw. We also manufacture self-drilling screws that can be fastened without pre-drilling holes in the steel plate.
This is a screw made of β-titanium alloy that overcomes the mechanical strength weakness of pure titanium.
We have achieved low prices for titanium alloy screws, which were previously expensive and difficult to obtain, by producing them through continuous header processing. In addition to high strength, lightweight, and excellent corrosion resistance, we have enhanced their beauty with anodizing treatment. We can manufacture sizes from M2 to M8.
We deliver the necessary types and quantities of parts in a set! This eliminates any excess or shortage, thereby improving work efficiency during installation.

Strongly bonded with metal and rubber through vulcanization! Sizes available from M1 to M20.
In fastening, there are many cases where the flexibility and adhesion of rubber are utilized to provide sealing or cushioning functions. However, since rubber alone cannot maintain strength, backup and holding power from metal washers are necessary, which affects cost performance. The "Leak-Proof Washer" has a strong adhesive force due to the vulcanized bonding of metal and rubber, resulting in minimal rubber escape during fastening. This prevents rubber from being caught in the threaded part, maintaining high sealing performance, as well as providing various functions such as vibration resistance, loosening prevention, shock absorption, surface scratch prevention, and insulation. Additionally, in relation to this product, Azuma Screw also offers "Leak-Proof Screws (Nuts)." 【Features】 ■ Strong adhesion of metal and rubber through vulcanized bonding ■ Material: Metal part (stainless steel), rubber part (neoprene, EPDM, etc.) ■ Size: M1 to M20 *For more details, please refer to the PDF document or feel free to contact us.
