Stainless Steel Carriage Bolt

Yellow Enterprises, established in 2017 in Pune, Maharashtra, is a leading manufacturer and supplier of Stainless Steel Carriage Bolts. Known for their strength, corrosion resistance, and precision engineering, our SS carriage bolts ensure reliable fastening performance across industrial and construction applications.

A Stainless Steel Carriage Bolt is a type of fastener designed with a round, dome-shaped head and a square neck just below the head. The square neck fits into a corresponding square hole (or grips into wood or metal), preventing the bolt from turning when the nut is tightened. This design ensures a smooth, tamper-resistant finish on the exposed side, offering both functionality and a neat appearance.

Manufacturing Expertise of Yellow Enterprises

At Yellow Enterprises, every Stainless Steel Carriage Bolt is manufactured with precision using high-grade stainless steel materials such as SS 202, SS 304, and SS 316. The company follows strict quality control procedures and international standards like DIN, ASTM, and ISO, ensuring each bolt meets the highest strength and corrosion resistance requirements.

Our state-of-the-art manufacturing facility in Pune is equipped with modern machinery, advanced threading systems, and quality testing instruments. A skilled team of engineers and technicians ensures dimensional accuracy, smooth finishing, and consistent mechanical properties across every batch.
