Threaded Fasteners
Threaded Fasteners are mechanical components with external or internal threads designed for secure and durable fastening solutions across multiple industries. These fasteners offer high tensile strength, vibration resistance, and ease of installation, making them essential in structural, industrial, and precision applications.
At Rajal Industries, we manufacture and supply a wide range of high-quality threaded fasteners in mild steel, stainless steel (304, 316), high-tensile alloys, and specialty coatings, ensuring optimal load-bearing capacity, corrosion resistance, and long-term durability.
