We are publishing a series on the basics of cap nuts!

第一工業 第一工業 鋲螺事業部(ネジ・ボルト・ナット等締結部品 製造販売. 静岡県浜松市)
We are publishing the newsletter series "Basic Knowledge of Cap Nuts," which was distributed from September to November 2017. A cap nut is a type of nut that is sealed on one side with a hemispherical cap, and it does not have a through hole. By covering the threaded part of a bolt, it excels in corrosion resistance, safety, and aesthetic appearance. Our company was the first in Japan to manufacture and sell bag nuts (Type 3, Category 2 cap nuts) with caps pressed and welded onto the nuts. Since then, we have responded to various applications and needs from our customers by manufacturing and selling a variety of bag nuts. For example, we offer lightweight and highly corrosion-resistant titanium cap nuts, SS-UFO nuts that can be tightened with a screwdriver, and SS insert cap nuts that can be embedded in resin, all tailored to meet your requirements. For more details, please refer to the related catalog. Feel free to contact us as well.

Bag Nut "SS-UFO Cap Nut"

It is a bag nut that can be tightened with just one driver, even in narrow spaces!

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 formed by pressing onto a nut. Since its launch, 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. From this bag nut series, we offer the "SS-UFO Cap Nut," which can be tightened with a screwdriver. The "SS-UFO Cap Nut" is a special bag nut with recesses (such as a cross hole) in the cap part. Even in tight spaces where a wrench cannot be used, this "SS-UFO Cap Nut" can be tightened with just one screwdriver.
