Daiwa kogyo Co.Ltd

We manufacture brake lining rivets, hermetic motor rivets, hollow rivets, and various types of rivets

We use header machines in the cold forging production method to forge wire materials and to manufacture rivets. The materials we use include iron, brass, and aluminum, and recently we have been focusing on hollow stainless steel materials. 
Among these products, we excel at hollow rivets with a hole at the tip of the rivet, and we can produce rivets 1.0 mm to 8.0 mm in shaft diameter and 1.0 mm to 160 mm in shaft length.

Our company's products
Lining rivets
Brake lining rivets
Used for drum brakes. 
Specifically, used as fastening parts to connect the friction material (lining) and the base part (shoe only) of a brake. 
These components support the wheels of trucks, the key to logistics, in the shadows, in areas that are usually not visible. 
Industrial machine rivets 
These are used for large-scale brakes on hoists, elevators, or wind power generators.
Stepped hollow rivets
Since the foundation of our company, we have been using a method that does not use any drill during machining to manufacture hollow rivets, which have a hole on an end surface of the rivet. 
In addition, we have also been certified as a KOEDO E-PRO in the first Kawagoe Manufacturing Brand for our hollow rivets with an ultra-thin bore diameter. 
We have succeeded in mass production of diameter-0.6 shoulder hollow rivets. 
We are proud of our sales results of 70 million units since 2006 as a component of hinged movable shafts.
Long hollow rivets
Long rivets are used for hermetic motors, which are electromagnetic components in the outdoor units of air conditioners. 
The rivets for these motors are over 100mm in length. 
There are only a few companies that have the facilities and technology to manufacture such long rivets. 
Our company has four machines that can manufacture long hollow rivets, and we have extensive experience in this field.
Special rivets
We also manufacture products with special specifications. 
We can machine them into any form, so please feel free to contact us.
Stainless steel hollow rivets
We satisfy your requests for difficult-to-machine stainless steel products and so on.
