The bag nut is the original of JIS Type 3! We offer a variety of product series including iron, stainless steel, titanium, and weld (welding) nuts.
The founder of Daiichi Kogyo Co., Ltd., Akira Suzuki, was the first in Japan to manufacture and sell a bag nut (JIS Type 3 cap nut) with a cap that is press-formed onto a nut. Since its release, it has received positive feedback for being lighter and more affordable compared to traditional cutting types, and it has evolved into a wide variety of forms to suit various applications. You can find it in places close to you, so please remember Daiichi Kogyo when you see it. 【Features】 ○ The head is hollow, making it lightweight and allowing male threads to be inserted to the tip of the cap, preventing exposure of the threaded part. ○ The design is smart and has excellent decorative qualities. ○ It is standardized and can be mass-produced.
