Water leak prevention washer

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 "water leak prevention washer" has a strong adhesive force due to the vulcanized bonding of metal and rubber, resulting in minimal rubber displacement 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, vibration absorption, surface scratch prevention, and insulation. Additionally, in relation to this product, Azuma Neji also offers "water leak prevention 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.

Clenching stud bolt "Joy Stud(R)-FH"

[New Product] Supports space-saving by reducing the protrusion of the head from fastening components!

The "JOISTUD(R) -FH" is a head-embedded clinching stud bolt that does not protrude from the fastening member after being pressed in. By minimizing the thickness of the head to the extreme, it becomes possible to press the entire outer circumference of the head into the fastening member. On the other hand, by providing nine circular recesses on the seating surface, it is possible to achieve a high anti-rotation effect by allowing the fastening member to fill these recesses during pressing. Additionally, since the recesses have an open shape in some parts, air can easily escape from here during pressing, promoting the flow of the fastening member into the recesses. 【Features】 ■Significantly reduces head protrusion from the fastening member ■Achieves high anti-rotation strength ■Ensures high pull-out strength *For more details, please refer to the PDF document or feel free to contact us.

Railway-related products: resin-coated bolts for electrical contact and anti-corrosion.

Bolts treated with coatings such as nylon-based and epoxy-based.

Electrolytic corrosion is a phenomenon where metal rapidly dissolves due to the flow of electricity from natural phenomena on the surface of the metal. Iron structures are painted, and this paint contains a lot of zinc, which provides rust prevention effects. However, there are many areas of corrosion on bolts that have been treated with hot-dip galvanized coating, especially in places that experience repeated wetting and drying or have high humidity. To help address these issues, we also sell bolts that have been coated with nylon-based and epoxy-based treatments. *For urgent or emergency cases, or for technical inquiries, please contact us directly through our website.*
