Matsukane Tekkousho Co., Ltd.

We have been providing hexagon bolts to the construction machinery industry for 35 years, with a focus on quality. 

Our strength lies in producing large parts such as large hexagon bolts. We employ hot forging to manufacture products. These include pinion shafts for construction machines including shovel cars, ship parts, reduction devices for hydraulic shovels and the like, auto parts, and other parts used in various situations. Our products are put through strict inspections and tests before shipping, which has allowed us to work with construction machine manufacturers for 35 years. All processes including thermal treatment, product inspection, and logistics are controlled in-house, and we ship our main hexagon bolt products as finished products. Our hexagon bolts for public highway companies have never been rejected.


Other presentation

[Company strength]
Our plant is located in an exclusive industrial district that allows 24-hour operation, so we have a high production capacity. We have strict inspection and testing procedures in place for pre-shipping products. This is why no products have been rejected by our construction machine manufacturer customers (for 35 years since the start of doing business), or by public highway companies. We have thorough quality control in place. Induction heating equipment is attached during production, which is equipped with a radiation thermometer to maintain an optimal forging temperature range from 1150 to 1250 °C at all times. We take full responsibility for quality and reliability, and there have been no accidents since the start of our company. 

[Business description]

Our company manufactures high-quality products with a high production capacity, and we make use of an induction heating furnace that is equipped with an automatic heating unit. Requirements regarding lead time, lot size, and variety are negotiable, and we will work hard to satisfy your needs as much as possible. Acceptable product sizes can be anywhere between diameter 25 to 200. We can use a die to forge products with a head diameter up to 400. We can also issue certificates, and satisfy various other needs as necessary. Our products have been delivered to public highway companies through a trading company for over 35 years, which attests to our high quality standards. 

[Representative's message]
Our company has been producing large bolts and other parts through hot forging since our establishment in 1953. This industry has been faced with needs for higher precision and products with higher added value. Our company has been able to establish advanced technological strength and high production capacity by actively developing new technologies, and making capital investments in pursuit of safety and reliability. We will remain committed to developing new technologies to satisfy customer needs. Our past transactions were mostly through trading companies, but we hope to work with customers directly to respond to their needs in a more reasonable and timely manner. 

[Company structure for market development/overseas expansion]
Our past sales efforts were made through trading companies. Our president knows everything about our high-quality, high-reliability products, and will conduct top-level sales from now on. Our plant manager is a 30-year veteran who enables us to thoroughly control quality and satisfy various customer needs, including quick deliveries. Our past sales include mass-produced parts for major construction machine companies, so we can handle any lot sizes, including mass production.
