Yaki-tsuka Nut Series

Bolt and nut anti-seizing coating! Natural finish is also available upon request for color preferences.

The "Yakituka Nut" is a heat-resistant nut made of stainless steel, coated with a multilayer plating (YK Coat) developed by Yudensha Co., Ltd. With its high adhesion, the plating is resistant to peeling, maintaining its anti-seizing effect even after repeated use. The dry finish eliminates drips like those from using lubricating oil, and no application time is required. Additionally, it features a distinctive muted color compared to typical stainless steel nuts, and due to the color difference from other stainless materials, we can accommodate requests for a natural finish where the outer layer is removed while leaving the three-layer plating on the screw part. [Features] - Can be applied to aluminum - Natural finish available - Other shapes and sizes can be accommodated *For more details, please download the PDF or feel free to contact us.

Stainless steel hex nut <with NF coating>

Recommended for domestic stainless steel bolts! Stainless steel hex nuts with excellent cost performance.

Stainless steel can sometimes cause the phenomenon of "galling/seizing" due to the friction heat generated during tightening, which expands the threaded area and makes it immovable. To solve this problem, our product applies a fluoropolymer resin thoroughly to control the friction coefficient during tightening, thereby suppressing the occurrence of seizing in bolt-nut engagements under normal conditions. Compared to domestic products, it offers excellent cost performance and does not reach the level of seizing torque coefficients even under conditions of repeated use up to five times. 【Features】 ■ All products have been selected from domestic manufacturers ■ Manufacturer's product warranty included (with engraving) ■ Superior cost performance compared to domestic products ■ Does not reach seizing torque coefficients even under conditions of repeated use up to five times *For more details, please refer to the PDF document or feel free to contact us.

Loosening prevention function screw "fix-F4(+) pan screw/WH"

No screw lock / no assembly! It won't peel off like a lock even after repeated use.

The "fix-F4(+) Nabebisu/WH" is a screw with a loosening prevention function that achieves weight reduction by eliminating the need for flat washers and spring washers. By removing the resistance type loosening prevention that uses nylon or silicone-based resin, which is more expensive than screws, cost reduction with screws becomes possible. Additionally, it prevents the tilting of screws caused by spring washers and the overlapping of flat washers, which can lead to stoppages in automated lines. 【Features】 ■ Significant cost reduction ■ Reusable ■ Achieves weight reduction by eliminating the need for flat washers and spring washers ■ No need for incomplete screw sections due to the thickness of incorporated parts ■ Prevents stoppages in automated lines *For more details, please refer to the PDF document or feel free to contact us.

Non-sticking! Equipped with anti-seizing "Yakituka Nut"

Prevent seizing of stainless steel bolts and nuts! With this, you won't have to worry about seizing anymore!

The "Yaki-tsuka nut" is an anti-seizing nut made of stainless steel that has undergone multi-layer plating (YK coat). With its high adhesion of the plating, it is resistant to peeling, and even after repeating tightening tests eight times, the anti-seizing effect remains. Thanks to its dry finish, there is no dripping like when using lubricating oil, and no application time is required.

Aluminized α treatment suitable for preventing galling and seizure of hex bolts and nuts.

It is highly resistant to corrosion, seawater, and heat, and does not suffer from corrosion degradation or deformation even at high temperatures!

◎What is Aluminaize α treatment… It is a processing method that involves performing low-temperature thermal diffusion treatment on the aluminum layer on the surface, allowing the aluminum layer to interdiffuse with the base material to form an alloy layer (Fe-Al intermetallic compound). ◎Why does it not seize… When the surface of the screw or the mating material reaches high temperatures, oxidation occurs, resulting in the formation of scale over 6μ. When removing the bolt, the generated scale accumulates (sticks) in the clearance between the female and male threads, causing seizing or galling. The scale from the Aluminaize α treatment is a maximum of 2μ, allowing it to roll within the clearance between the female and male threads when removing the bolt, acting as a lubricant and preventing seizing and galling. ◎Materials suitable for Aluminaize α treatment Iron, cast iron, steel, alloy steel, SUS materials, heat-resistant steel, titanium, Inconel, Hastelloy, etc. *For more details, please contact us or download the PDF.

"Aluminize α treatment" that prevents biting and seizure.

Alloy steel with excellent properties of heat resistance, corrosion resistance, sulfide resistance, seizure resistance, and wear resistance.

It refers to "alloy steel," which has excellent properties such as heat resistance, corrosion resistance, sulfide resistance, seizure resistance, and wear resistance, created by new technology on the surface of iron-based materials. This can be generated on all conventional thermal materials (including stainless steel and cast iron) and can be widely used to enhance the added value of both conventional and new products. This "alloy steel" is formed by the "mutual diffusion phenomenon" of iron and aluminum.
