Eye bolts in all variants

Eye bolts are among the most proven fasteners when it comes to the secure fastening, pulling, lifting, or securing of components.

Our product range includes:

Eye bolts in common standard sizes: Eye bolts M6, M8, M10, M12, M16, M20 and more
Also available in larger dimensions and special sizes upon request
Stainless steel eye bolts – ideal for outdoor use or aggressive environments – or other materials
Variants with internal thread for special applications
Tested quality according to DIN 444 or custom-made according to drawing

Materials & Surfaces for the Highest Demands of Eye Bolts

The selection of the right material is crucial for the performance and lifespan of an eye bolt. Depending on the application, different metallic materials are used. Our eye bolts, like all other screws, are available in various materials and coatings:

Steel plain / galvanized – cost-efficient & proven

Stainless steel A2 (V2A) / A4 (V4A) – for particularly humid, salty or aggressive environments

Black eye bolts – galvanized, blued, or phosphated

Special materials – e.g. heat-resistant steels or duplex steels

You can find an overview of all available materials on our separate material page

Specialist for special fasteners in pressure equipment construction

We offer you reliability in safety-critical applications.

A particular focus of ASO Schrauben is, among other things, the production of special fasteners for pressure equipment. Our connecting elements are used wherever maximum safety, material quality and manufacturing precision are required – for example in pressure vessels, flange connections, heat exchangers, valves or steam systems, in turbine construction and in classic mechanical engineering.

Thanks to many years of experience and modern manufacturing technologies, we produce screws according to drawings or special standard specifications – even from a quantity of 1!

Our production meets the strict requirements of the Pressure Equipment Directive (PED 2014/68/EU) and relevant regulations such as AD 2000-Merkblatt W0. The corresponding certificates (e.g. 3.1 / 3.2 according to EN 10204) document the quality and traceability of our products – a clear added value for safety-critical applications.

Advantages of an Eye Bolt from ASO Schrauben

Good to know: Eye bolts in detail

An eye bolt is a screw with a closed ring – the so-called “eye” – at one end. This ring serves as a suspension, attachment, or fastening point. The other side is equipped with a metric external thread that can be easily screwed into machines, components, or supporting structures.

DIN 444 eye bolts are particularly frequently used – this standard defines cylindrical eye bolts with a long shank and thread run-out. They are especially suitable for dynamic loads and enable safe operation even under tensile or shear stress.

Regardless of whether you need an M12 stainless steel eye bolt, a lightweight M6 eye bolt, or particularly robust M16 stainless steel eye bolts – we deliver reliably and precisely according to your requirements.

We manufacture everything for you - whether according to European or international standard!

Our special fasteners are used where standard solutions do not fit – for example, at high pressure, extreme temperatures, or aggressive media. Special fasteners made of special TÜV-tested pre-material are often the only solution in the industry for reliably implementing complex, safety-relevant applications.

At ASO Schrauben, the perfect connection is our focus – not only technically, but also in cooperation with our customers. With individual solutions and high quality, we support your projects precisely.

Application areas and advantages of our eye bolts

Eye bolts are used in various industries, such as mechanical and plant engineering, steel and metal construction, lifting technology, apparatus construction and housing assembly, marine sector, construction, event and stage technology, or applications with high tensile or transverse forces. Among other uses, DIN 444 eye bolts are employed – for example, as anchor points for ropes or eyelets, in offshore technology, or for fastening suspensions or supports.

Our other types of fasteners

Special fasteners and custom screws can be manufactured in very different designs and functional types. Our common screw types include tension bolts, threaded rods, and stud bolts, which are frequently used in pressure equipment or flange connections. Further variants include socket head cap screws, hex head screws, or special screws with specific thread forms. By combining different head shapes, thread types, and materials, highly specialized fasteners are created that are precisely tailored to your requirements.
