Blocks water, oil, and air! Widely applicable for outdoor equipment, underwater devices, medical devices, and more!
We would like to introduce our original metal product, the "Seal Washer." It excels in oil resistance, heat resistance, and weather resistance, preventing the ingress of water, oil, and air when the screw is tightened, thanks to the rubber's tight fit. We particularly recommend the thick body for outdoor use. 【Features】 ○ Can be used with various screw shapes (except for flat screws) ○ Excellent oil resistance, heat resistance, and weather resistance ○ Can be used even with large countersinks due to its wide seating surface (refer to the size chart) ○ The rubber tightly adheres when the screw is tightened, preventing the ingress of gases and liquids (the tightening torque depends on the strength classification of each size) ○ Can be reused repeatedly as long as there is no damage to the rubber ○ Especially recommended for outdoor use is the thick body For more details, please contact us or download the catalog.

Company information
Our company's history dates back to April 1957, and thanks to your support, we are approaching nearly half a century. Over these 50 years, we have embarked on the development of numerous new products and successfully achieved mass production. We take pride in this accomplishment and the reliability that has been recognized as a result. The 1950s was a time based on Japan's post-war economic recovery, and from the 1960s onward, it was an era that supported rapid economic growth, particularly marked by remarkable developments in industrial products. Our main business, screws (fastening components), is indispensable, and the standard screws we handle alone number in the hundreds of thousands, with the addition of special products bringing the variety close to infinite, and even now, their value remains unchanged. Since then, we have entered the era of electronics and digital industries, and the industrial structure has shifted from mass production and mass sales to a time of small lots and diverse varieties. Currently, the demands of the industrial world are for originality, quality standardization, and speed, with the primary challenge being the reduction of production costs. To overcome this difficult challenge, the first step is the skill enhancement of all employees, united as one company.
