Screws are one of the most essential types of fasteners used across industries for mechanical assemblies, construction, and engineering applications. At Neonox Overseas, we offer a comprehensive range of screws manufactured in premium quality materials and designed to meet international standards for strength, durability, and precision. Screws are characterized by their helical external threading which allows them to be driven into materials with or without the use of pre-tapped holes. Depending on the design and application, screws can provide permanent or semi-permanent fastening solutions. Our range includes machine screws, socket head cap screws, self-tapping screws, and wood screws, each engineered to provide excellent holding power and resistance to vibrations. Machine screws are widely used in machinery, electronics, and industrial equipment where they can be fastened into tapped holes or used with nuts. Socket head cap screws are designed for applications requiring a clean appearance and high torque, often used in automotive and aerospace industries. Self-tapping screws, on the other hand, are designed to cut their own threads during installation and are ideal for sheet metal, plastics, and lightweight constructions. Wood screws are designed specifically for woodworking and construction applications where they offer secure joining without splitting the wood.
We manufacture screws in a wide variety of materials including stainless steel, duplex steel, super duplex steel, nickel alloys, titanium, copper nickel, Alloy 20, and SMO 254, ensuring compatibility with diverse environments and performance requirements. Stainless steel screws are corrosion resistant and widely used in general engineering, food processing, and chemical industries. Duplex and super duplex screws provide higher strength and resistance to chloride-induced stress corrosion cracking, making them suitable for marine and offshore industries. Nickel alloy screws are highly resistant to oxidation, scaling, and extreme environments, making them ideal for chemical processing and aerospace applications. Titanium screws offer exceptional strength-to-weight ratio and biocompatibility, suitable for aerospace, marine, and medical industries. Copper nickel screws are known for their resistance to seawater corrosion and are extensively used in shipbuilding, desalination, and marine equipment. Alloy 20 screws are designed for applications involving sulfuric acid and other aggressive chemicals, while SMO 254 screws provide superior resistance to pitting and crevice corrosion in seawater and chemical environments.
At Neonox Overseas, all screws are manufactured in compliance with ASTM, ASME, DIN, BS, and ISO standards. They are available in multiple surface finishes such as passivated, zinc-plated, hot-dip galvanized, black oxide, and PTFE coating. The dimensional range covers sizes from M2 to M72 with lengths up to 300 mm, ensuring suitability for light-duty to heavy-duty applications. Customers can choose from different drive styles such as slotted, Phillips, Torx, and hex socket, based on their installation requirements. Every screw undergoes stringent quality checks for tensile strength, hardness, corrosion resistance, and dimensional accuracy. With a commitment to timely delivery and customer satisfaction, Neonox Overseas ensures that our screw fasteners meet the most demanding industrial requirements worldwide. Whether for standard applications or custom-engineered solutions, our screws provide reliable performance and long-term durability in all operating conditions.
