Cable clamps

Circlips

In our extensive range of fastening products, we start with our circlips, designed to hold components in place, ensuring a firm, secure assembly. These rings are made from materials such as carbon steel, stainless steel, bronze and various special alloys. We also offer them with galvanised, black-oxide and powder-coated finishes. They are ideal for machinery, the automotive industry and construction equipment, where stability and safety are essential.

Retaining rings

Continuing with our range of 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 their ease of assembly and disassembly, allowing quick maintenance without compromising the safety of the assembly. They are made mainly from carbon steel and stainless steel, with finish options such as black oxide, galvanised or phosphated to increase resistance to wear and corrosion. Retaining rings are widely used in the mechanical, hydraulic and automotive industries, ensuring a firm anchorage and a long service life in applications subject to constant movement or pressure.

Spiral rings

In parallel, within our fastening products we offer spiral rings, which provide a robust retention solution, especially useful in applications that need to withstand high loads and vibration, or that present difficulties in accessing the assembly area. These rings are made from high-strength steel, stainless steel and phosphor bronze, and can have finishes such as zinc plating or nickel plating, among a wide range of options. These rings are essential in transmissions, motors and aerospace applications. Their ability to adapt to different operating and environmental conditions makes our spiral rings a preferred choice for many engineers.

Washers

Washers are another of our fastening products at OSN. They play a crucial role in distributing the load evenly and preventing loosening in threaded joints. They are available in steel, stainless steel, copper or aluminium, with polished, galvanised and anodised finishes. Our washers are widely used in electronics, construction and manufacturing. Their versatility and strength ensure stability in a range of applications, from electronic devices to large structures.

Pins

Our pins and spring pins are ideal for securing components in a wide variety of industrial applications. They are made mostly from carbon steel or stainless steel, with galvanised or black-oxide finishes. OSN pins are essential in mechanical assemblies, support structures and precision equipment. Their reliability and durability guarantee optimal performance in the most demanding conditions.

High-quality bolts and screws

We must also mention our extensive range of bolts and screws, of all types, designed to offer reliable, durable fastening, with materials such as steel, stainless steel, aluminium or titanium alloys, and galvanised, black-oxide or ceramic-coated finishes. Our screws are fundamental in construction, automotive and heavy machinery. Each one is designed to offer maximum strength and durability, ensuring a secure, efficient assembly.

Nuts

OSN nuts perfectly complement our range of bolts and screws, guaranteeing a 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.

Clamps for securing

For applications that require securing pipes, cables and other components, our clamps are designed to offer a secure, durable solution. They are made from stainless steel, galvanised steel or aluminium, with polished, rubber-coated, epoxy and even anodised finishes. Our clamps are used, for example, 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.

Cable clamps

Finally, we offer high-quality cable clamps that ensure efficient, orderly management of cables and conductors. They are available in stainless steel, with natural or anti-corrosion finishes. Our cable clamps are essential in electronics, telecommunications and electrical installations, among many other sectors. The organisation and safety they provide ensure optimal performance in any environment.

Availability of materials and finishes

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), but we can offer any alloy that suits your needs. Almost all our carbon steel products come with a phosphate coating to prevent corrosion, although many finishes are available depending on the end-user requirements (zinc plating, GEOMET, and so on).

OSN supports you throughout the entire purchasing process. In addition to offering you a quote with the best price and delivery time, we provide technical drawings and data sheets for any of the materials. We offer all kinds of certifications and dimensional studies, as well as the different steps of a PPAP approval process. Our aim is to give you fast advice and technical support before and after the sale, to make sure you get exactly what you need, at the right time, because your time is our commitment.

We take pride in offering fastening products that meet the highest standards of quality and performance. With a wide variety of materials, alloys and finishes, our products are designed to exceed your expectations in any industrial application.
