We provide a diverse range of Fasteners, including Bolts, Screws, Threaded Rods, Washers, Stud Bolts, and Carriage Bolts. Our Fasteners are produced using superior raw materials and undergo stringent testing to ensure they meet the highest standards.
Types of Fasteners
Fasteners come in various types, each serving distinct purposes:
- Externally-Threaded Fasteners: Includes Bolts, Screws, and Studs. Bolts are used with nuts and washers for removable connections. Screws work with internally threaded holes, and Studs join materials through internal threads.
- Nuts: Used with bolts to secure materials. Types include Hexagonal Nuts for general use, Lock Nuts for secure connections, and Wing Nuts for manual adjustments.
- Washers: Enhance performance by distributing force and protecting fastened objects. Types include Flat Washers, Spring Washers, Cup Washers, and Repair Washers.
- Rivets: Permanent fasteners used to join materials, with types such as Solid Rivets, Blind Rivets, and Tubular Rivets.
Our inventory encompasses a diverse range of fastener grades, including Stainless Steel 304, Hastelloy, Mild Steel, Super Duplex Steel, Nickel Alloy, among others. As a leading fastener stockist in India, we export our fasteners to numerous countries around the globe. Our products are extensively utilized across various sectors, including the chemical, power generation, oil and gas, and pharmaceutical industries.
