Since it is transparent, visual inspections can be conducted while it is still attached during maintenance! Despite its glass-like transparency, it boasts high impact resistance and protects bolts and nuts from rust!

"Protect-kun" is a bolt and nut rust prevention cap that protects against wind, rain, and mud, preventing rust. It completely covers the bolts and nuts, providing strong waterproofing and dustproofing while allowing for visual inspection through its transparent material. Despite its glass-like transparency, it boasts impact resistance over 250 times that of glass. With high water tightness, it prevents deterioration of bolt structures due to rust, facilitates maintenance inspections, and contributes to the longevity of infrastructure. 【Features】 ■ Prevents rust ■ Visible interior ■ No filler required ■ Waterproof and dustproof ■ Allows visual inspection while installed *For more details, please refer to the PDF document or feel free to contact us.

Phone number/address

Since its establishment in 1971, our company has consistently sold industrial rubber products, plastic products, and sponge products. We prioritize customer satisfaction and have made "creating products that meet customer needs" our management policy. However, in this challenging economic environment, it is nearly impossible for small and medium-sized enterprises like ours to survive by merely "pursuing customer satisfaction." Therefore, we consciously focus our limited management resources on our company's "strengths" and work to "enhance those strengths," which serves as our differentiation strategy from other companies. We handle many products that others cannot produce or do not want to make, and we believe that providing such products contributes to society. Additionally, our company is characterized by "speed," "positivity," and "challenge." These principles serve as our guidelines for action and are firmly rooted in our corporate DNA.
