Pathan Durgadevi Udyan, Ground Floor, 25 Plot No 74/80, Patra Chawl, Maruti , Mandir Marg, Second Street, Girgaon, Mumbai, Maharashtra 400004Our speciality at Tubotech, one of the best piping and tubing manufacturers in India, is to deliver to you on a platter high-performance Stud Fasteners. We have designed them specifically to meet the demand’s of today’s high-quality engineering, construction, and industrial applications.
Typically, studs are threaded rods that do not possess a head. They are used as a superior clamping force and reliable alignment specifically where installation and reinstallation activities are commonly used. Our Stud Fasteners have been engineered to be durable, possess maximum strength, and have high corrosion resistance.
Above all, we at Tubotech produce Stud Fasteners in compliance with international standards like DIN, ASTM, and ISO. In addition, they are available made from an array of wide range of materials. They include: carbon steel, stainless steel, alloy steel, and special coating.
