We are dedicated to supplying high-quality, durable fastening solutions designed to meet the most demanding requirements of our customers across a wide range of industrial sectors.
We manufacture and supply a wide variety of fastening elements such as circlips, spiral retaining rings, washers, pins, clamps, bolts and screws, nuts and cable ties, all of them compliant with the strict DIN, ANSI or JIS standards, among others. These standards ensure that our fastening products deliver maximum performance and safety in any industrial application.
In our extensive range of fastening products, we start with circlips, designed to hold components in place and ensure a firm, secure assembly. These rings are manufactured in carbon steel, stainless steel, bronze and a variety of special alloys. We also offer them with zinc-plated, blued and powder-coated finishes. They are ideal for machinery, the automotive industry and construction equipment, where stability and safety are essential.
Continuing with our fastening systems, we offer retaining rings, or snap rings, a practical and versatile solution for securing components on shafts and in housings. These rings are characterised by how easily they are fitted and removed, which allows quick maintenance without compromising the safety of the assembly. They are manufactured mainly in carbon steel and stainless steel, with finish options such as blued, zinc-plated or phosphated to increase resistance to wear and corrosion. Retaining rings are widely used in the mechanical, hydraulic and automotive industries, guaranteeing firm anchoring and a long service life in applications subject to constant movement or pressure.
Alongside these, our fastening products include spiral retaining rings, which provide a robust retention solution, particularly useful in applications that have to withstand high loads and vibration. These rings are manufactured in high-strength steel, stainless steel and phosphor bronze, and can be supplied with finishes such as zinc or nickel plating, among a wide range of options. They are essential in transmissions, motors and aerospace applications. Their ability to adapt to different operating and environmental conditions makes them a preferred choice for many engineers.
Washers are another of our fastening products at OSN. They play a crucial role in distributing the clamping load evenly and preventing loosening in threaded joints. They are available in steel, stainless steel, copper or aluminium, with polished, zinc-plated and anodised finishes. Our washers are widely used in electronics, construction and manufacturing. Their versatility and strength ensure stability in applications ranging from electronic devices to large structures.
Our pins and elastic pins are ideal for securing components in a wide variety of industrial applications. They are manufactured mainly in carbon steel or stainless steel, with zinc-plated or black oxide finishes. OSN pins are essential in mechanical assemblies, support structures and precision equipment. Their reliability and durability guarantee optimum performance in the most demanding conditions.
Our extensive range of bolts and screws includes fasteners of every kind, designed to deliver reliable, durable fastening in materials such as steel, stainless steel, aluminium alloys and titanium. Finishes include zinc plating, blueing and ceramic coatings. Our screws are fundamental in construction, the automotive industry and heavy machinery. Every screw is engineered for maximum strength and durability, ensuring a safe and efficient assembly.
OSN nuts are the perfect complement to our range of bolts and screws, guaranteeing secure, stable fastening in a variety of industrial applications. They are available in steel, stainless steel or brass, among other options, with zinc-plated, nickel-plated or anti-corrosion finishes. Our nuts are indispensable in infrastructure, mechanical assemblies and electrical equipment. Their high-quality design and manufacture ensure reliable performance at all times.
For applications that require tubes, cables and other components to be secured, our clamps are designed to provide a safe, durable solution. They are manufactured in stainless steel, galvanised steel or aluminium, with polished finishes, rubber and epoxy coatings and even anodised versions. Our clamps are used on hoses, plumbing installations, air conditioning systems and in the marine industry. Their robustness and versatility make them ideal for a wide range of applications.
We offer high-quality cable ties that ensure efficient, orderly management of cables and conductors. They are available in stainless steel, with natural or anti-corrosion finishes. Our cable ties are essential in electronics, telecommunications and electrical installations, among many other sectors. The organisation and safety they provide guarantee optimum performance in any environment.
Our industrial fastening supplies are available in carbon steel (SAE 1060-1090, C67S, C75S, 65Mn, among others) or stainless steel (DIN 1.4122, AISI 302, AISI 304, AISI 316, AISI 420, PH 15-7 Mo, PH 17-7). We can offer any alloy that suits your requirements. Almost all our carbon steel products come with a phosphate coating to prevent corrosion, although many finishes are available depending on the end user’s requirements (zinc plating, GEOMET and others).
OSN supports you throughout the whole purchasing process. As well as a quotation with the best price and lead time, we provide technical drawings and datasheets for any of the materials. We offer all kinds of certifications and dimensional studies, as well as the various stages of a PPAP approval process. Our aim is to give you fast advice and technical support before and after the sale, so that you get exactly what you need, when you need it, because your time is our commitment.
