This is a stainless steel hex fine nut that has been machined to be as thin and compact as possible. Its thickness is about half that of the three types, and its opposite sides are also one size smaller than commercially available products.
Using double nuts is also effective for preventing loosening. Additionally, there is a slightly thicker slim type available.
A product with a ball chain and ring attached to a knurled nut, where the knurled nut and ball chain can rotate independently in 360 degrees.
The nuts, chains, rings, and fittings are made of all stainless steel. The length of the chain can be selected from 7 sizes according to the intended use.
By inserting this product into a round hole in a thin plate, you can create screw holes in metal plates, wood, etc., where screw processing is not possible.
This structure is tightened with a toothed washer and a hex nut without using special tools. By using the included toothed washer, you can use it without worrying about loosening. Since it has a hex head type, it can be easily tightened with a wrench or similar tool.
This is a nylon butterfly (cosmetic) nut that is strong, wear-resistant, has excellent lubricity and chemical resistance, and is oil-resistant. It has a shape that is easy to turn with your fingers and allows for good grip.
The resin part is available in two colors: white and black.
This is a conversion insert nut with internal and external threads. It can be installed in a threaded hole to reduce the size.
Conversely, you can increase the size by attaching it to the female thread. There is a slotted groove for easier tightening.

I will explain about screws that are prone to seizing in a blog format!
In terms of screw fastening itself, I will provide some examples of what tends to seize easily. For instance, in the fastening of hex bolts and hex nuts, when using JIS supplementary items such as JA hex nut type 1 and high nuts with greater height, the high nuts are more prone to seizing. In the case of high nuts, the grip length of the threads between the hex bolt and hex nut becomes longer, which increases the contact area between the male and female threads, generating friction heat more quickly and at a higher level. As a result, thermal expansion occurs, leading to the threads seizing. *For more detailed content of the blog, you can view it through the related links.

Strengthening Guide for Screws (Vol. 48)! Introduction to the strength classifications of steel nuts and stainless steel nuts.
The strength classification of steel nuts is represented only by numbers. There are eight types: "04," "05," "5," "6," "8," "9," "10," and "12," but in everyday use, they are rarely encountered based on my experience. The likely reason is that there are few, if any, commercially available products that clearly indicate the strength classification, which results in them being seldom used in daily orders and transactions. Please understand that this is solely my personal opinion. So, how are daily orders and transactions conducted? In the case of nuts, it is mostly done by material name rather than strength classification. *For more detailed content of the blog, please refer to the related links.
