Honesty Steel & Alloys Ltd. is a manufacturer, exporter, and supplier of Stainless Steel 304/304L Fasteners, Our Stainless Steel 304/304L Fasteners are manufactured and supplied in different sizes, dimensions, grades, standards, finishes, thread configurations, and supply forms to meet diverse industrial requirements.
Stainless Steel 304/304L Hex Bolts are six-sided externally threaded fasteners designed for applications where reliable mechanical fastening and good corrosion resistance are required. Their hexagonal heads allow installation and removal using standard tools.
Stainless Steel 304/304L Nuts are internally threaded fasteners used together with bolts, screws, and threaded rods. Hex nuts are among the most common types and are available in metric and imperial dimensions. Their corrosion resistance makes them suitable for general industrial and outdoor applications.
Stainless Steel 304/304L Washers distribute the load of a threaded fastener across the contact surface and can help protect the mating surface. Plain, flat, spring, lock, fender, square, and customized washers are available. SS 304 Eye Bolts have a looped head and are used for fastening, anchoring, securing, and lifting-related applications where the design and rated capacity are appropriate. Customized eye dimensions and thread configurations can be supplied.
Stainless Steel 304/304L Stud Bolts are commonly used for flanged connections, equipment assembly, piping systems, and industrial applications. Studs can be supplied fully threaded or with specified thread lengths depending on the application. SS 304 Socket Head Cap Screws feature an internal hexagonal drive and compact cylindrical head. They are suitable for applications where installation space is limited and a clean, compact fastening arrangement is required. SS 304 Anchor Bolts are designed to secure equipment, structural components, fixtures, and other assemblies to concrete or other substrates. Various configurations can be supplied according to installation requirements.
