Fasteners are essential components in construction, mechanical, automotive, and engineering industries. They are used to join two or more objects securely without causing any damage to the material. Turnon Alloys specializes in manufacturing high-performance fasteners built to endure extreme environments and meet global quality benchmarks. Our products meet rigorous ASTM A193, ASTM A194, ASTM F593, ASTM F594 and equivalent ASME B18.2.1 standards.

A fastener is a hardware device that mechanically joins or affixes two or more objects together. The range includes bolts, nuts, screws, washers, rivets, and anchors. The most common materials used are stainless steel, carbon steel, alloy steel, and non-ferrous metals. At Turnon Alloys, we engineer every piece for strength, reliability, and durability to fit diverse industrial demands.
One major advantage of fasteners is their easy installation and removal, which allows components to be disassembled without damage. They are cost-effective, provide strong load-bearing capacity, and require minimal maintenance. Their versatility makes them vital in applications from oil & gas to aerospace. As leading Fasteners Stockists, we ensure each product adheres to exact specifications for optimal performance.
Turnon Alloys supplies to customers worldwide, and fasteners are referred differently based on regional standards. In the USA, they are often produced per ASTM/ASME standards. In Europe, EN and DIN standards apply. In the UK, BS standards are used, while in Japan, fasteners conform to JIS norms. In India, IS standards dominate the market. We manufacture to suit all these global benchmarks.
As trusted Fasteners Suppliers, Turnon Alloys keeps an extensive inventory ready for global dispatch. Our commitment to consistent quality and precision machining makes us a top choice for bulk and customized orders. We are also experienced Fasteners Stockists, maintaining large volumes of standard and non-standard grades to meet urgent project requirements.
