When you're sourcing metric fasteners, it's not just about specs and sizes; it’s about performance in the real world. Engineers, buyers, and project managers want to know: Where is this fastener used? What makes it a better choice for my environment or industry?

At Eurolink Fastener Supply Service, we don’t just supply metric fasteners; we help solve real problems. Whether it’s saltwater corrosion, structural load demands, or high-torque applications, our customers rely on us to deliver fasteners that perform reliably in the field, not just on paper.

In this post, we’re highlighting the common applications, industries, and project types for some of our most in-demand products. Each one has a specific purpose, and we’ve seen firsthand how the right fastener can make the difference between failure and long-term success.

A4-80 Stainless Steel Fasteners

Ideal for: Marine, food-grade, chemical, and outdoor environments
Industries: Shipbuilding, water treatment, food processing, coastal infrastructure, medical equipment

A4-80 Stainless Steel fasteners set the bar for strength and corrosion resistance. Manufactured from austenitic stainless steel and hardened to meet Class 80 tensile strength, these fasteners are built for aggressive environments, especially where rust, salt, and chemical exposure are serious concerns.

Common Applications Include:

  • Marine and Offshore Projects: A4-80 fasteners are regularly used in shipbuilding, offshore platforms, docks, and other saltwater-adjacent structures where corrosion resistance is non-negotiable.

  • Food and Beverage Processing Equipment: Their non-reactive surface makes them perfect for environments requiring hygienic, food-safe construction.

  • Outdoor Structures: A4-80 stainless is a top choice for outdoor railings, walkways, stainless steel signage, and architectural features in coastal or high-moisture regions.

Eurolink Insight:
We’re proud to be the largest stockholder of A4-80 metric fasteners in North America, which means we’re often the first call when customers need corrosion-resistant solutions fast.

Hot Dip Galvanized 8.8 Hex Head Cap Screws (Tapped-Undersized)

Ideal for: Outdoor steel structures, heavy equipment, transmission towers
Industries: Construction, utilities, infrastructure, renewable energy

Hot dip galvanizing provides robust corrosion protection, but often comes at a cost; standard threads can seize or fail due to plating build-up. That’s why Eurolink’s tapped-undersized hot dip galvanized (tZn) hex head cap screws are engineered specifically for compatibility after coating, ensuring proper fit and torque.

Common Applications Include:

  • Utility Poles and Transmission Towers: Galvanized fasteners are standard in power and utility structures due to their durability in outdoor environments.

  • Structural Steelwork and Fabrication: Used in connecting beams, braces, and frames, especially where long-term corrosion resistance is critical.

  • Heavy Equipment Assemblies: Agricultural and industrial machinery benefit from hot dip galvanized fasteners where exposure to dirt, chemicals, or outdoor use is common.

Eurolink Insight:
Eurolink is proud to be the only stocking distributor of these tZn hex head cap screws in North America.

Metric Structural Bolts – Galvanized and Plain Finish

Ideal for: Bridges, buildings, heavy steel structures
Industries: Civil engineering, infrastructure, transportation, industrial construction

When safety and performance are paramount, structural bolts in Class 10.9 steel deliver the tensile strength needed for critical connections. Available from M12 to M30 and offered with full HV sets (nuts and washers), our structural bolts support projects that demand reliability under load and in the elements.

Common Applications Include:

  • Bridge Construction and Rehabilitation: Structural bolts are critical in joining truss components and support beams.

  • Steel Building Frames: Used in factories, warehouses, and other industrial builds where joint integrity is essential.

  • Transportation Infrastructure: Applied in rail, highway overpasses, and seismic retrofitting.

Eurolink Insight:
These bolts often come with long lead times, but not at Eurolink. Our pre-stocked metric structural bolts and relationships with European manufacturers allow us to deliver on tight schedules. 

Metric Torx Screws

Ideal for: Electronics, automotive, tamper-resistant assemblies
Industries: Consumer electronics, industrial equipment, vehicle manufacturing, aerospace

Torx drive fasteners offer superior torque transmission and are known for their ability to resist cam-out under high torque. Their star-shaped drive allows for better tool engagement and more precise installation, especially in automated environments.

Common Applications Include:

  • Electronics & Circuit Boards: Small Torx screws are ideal for devices where tamper resistance and compact assembly matter.

  • Automotive Interiors and Engines: Used in dashboard assembly, sensors, and under-hood components requiring consistent torque.

  • Industrial Equipment: Torx screws are often used in equipment where vibration, safety, or maintenance concerns make loose fasteners unacceptable.

Eurolink Insight:
A recent customer needed M6 x 40 ISO 14579 A2 Torx screws and couldn’t find them through their standard supply chain. We not only had most sizes in stock, but we also arranged expedited air freight for the rest and delivered in under 10 days. That project stayed on track, and the customer avoided a snafu.

Why Application-Focused Fastener Sourcing Matters

Fasteners are more than just components; they’re the quiet heroes behind successful projects. The wrong fastener can lead to corrosion, failure, or costly downtime. That’s why Eurolink doesn’t just sell metric fasteners; we match the right product to your specific industry, environment, and performance needs.

From marine-grade stainless to structural bolts to tamper-resistant Torx, we maintain deep inventory and application knowledge that helps engineers, buyers, and distributors move faster and smarter.
