Metric fasteners are the backbone of modern manufacturing. From the engine of your car to the assembly lines of global production plants, metric bolts, nuts, screws, and washers are relied on for their precision, versatility, and global standardization.
At Eurolink Fastener Supply Service, we specialize in sourcing hard-to-find and high-performance metric fasteners, helping manufacturers, engineers, and distributors across industries get what they need, when they need it.
This guide takes a deeper dive into the most common uses for metric fasteners across key industries, explores why the metric system is the standard globally, and highlights how Eurolink supports customers with technical expertise and deep in-stock availability.
Metric fasteners are measured in millimeters and follow international specifications such as ISO, DIN, and EN standards. This makes them ideal for global compatibility, repeatable performance, and ease of sourcing across borders.
Key advantages include:
Whether you’re building a truck chassis or a solar panel frame, there’s a metric fastener designed for your exact application, and Eurolink can help you find it.
The automotive industry has used metric fasteners for decades, starting with European vehicles and eventually adopted by American manufacturers to ensure tooling compatibility and simplify supply chains.
Even American-made cars now rely heavily on metric sizes. This shift ensures that repair shops and assembly plants only need one set of tools and supports global vehicle serviceability.
Our stocked metric Torx screws (ISO 14579) are a top seller for customers in automotive and industrial assembly lines. These star-drive screws reduce cam-out and improve torque control, perfect for repeatable installation and tamper resistance.
In aviation, every component must meet strict standards for performance, weight, and durability. That’s why metric fasteners, especially in stainless steel or alloy steel grades are essential for aircraft design and assembly.
Aviation fasteners must be lightweight, high-strength, and corrosion-resistant. Eurolink supplies metric stainless steel and alloy steel fasteners that meet these demands with confidence.
Global manufacturers like Procter & Gamble and Xerox shifted to metric standards decades ago, not just for product assembly, but for maintaining machinery, minimizing part inventories, and simplifying sourcing.
Metric hardware ensures interoperability across international teams and vendors, streamlining operations and maintenance.
Eurolink stocks key industrial fasteners, including hot dip galvanized Class 10.9 bolts and structural HV sets, which are ideal for heavy equipment and factory builds exposed to moisture, chemicals, or outdoor environments.
For projects like bridges, steel buildings, and public infrastructure, metric structural fasteners deliver the strength and corrosion resistance required to meet both local codes and international specifications.
Eurolink supplies EN 14399-4 heavy hex bolts, nuts, and washers, including hot dip galvanized (HDG) finishes for maximum durability in outdoor and corrosive environments.
Our stocked line of Hot Dipped Galvanized structural bolts (tZn thread) includes M12 to M30 sizes with material test reports (MTRs) available on request.
Electronics manufacturers often rely on fine-pitch metric screws and Torx drive designs for small-scale, high-precision assemblies.
Metric screws, such as M2 to M6 Torx or pan head screws, are designed for tight tolerances, precision torque settings, and repeatability in automated manufacturing.
While metric fasteners are globally standardized, some specs and sizes can be difficult to source, especially when working with specialty coatings, fine threads, or legacy equipment.
At Eurolink Fastener Supply Service, we’ve spent more than 25 years helping U.S.-based companies source:
We keep inventory ready for fast delivery on high-demand and hard-to-find metric products, including:
