Nakamura Stainless is a well-established manufacturer and supplier from Pulau Ujong, Singapore, and it provides various grades of high-quality stainless steel fasteners. Some of its major products are stainless steel 420 fasteners, which have extra strength, hardness, and resistance to corrosion. Designed for accuracy and performance, the fasteners are perfect for applications in harsh industrial conditions. Nakamura Stainless integrates quality materials with state-of-the-art manufacturing methods to deliver efficient, long-duration fastening solutions. Their 420-grade fasteners are highly relied upon by professionals in construction, automotive, marine, and mechanical industries for their strength and high performance against stress and wear.
Stainless steel 420 fasteners are produced using a high-carbon martensitic stainless steel alloy consisting of around 12 to 14 percent chromium, with traces of manganese, silicon, phosphorus, and sulfur. This composition allows good hardness and average corrosion resistance. Mechanically, they possess a tensile strength of between 700 and 850 megapascals and can be heat-treated to attain a hardness of up to 50 HRC. These bolts and nuts have good wear resistance and are suitable for usage in cases where both strength and durability are essential, especially in situations with friction, pressure, or high temperatures.
