In the world of fasteners, coating isn't cosmetic — it's critical.
A mismatch between fastener finish and application environment can lead to corrosion, structural failure, downtime, and even legal liability.
Yet, most professionals — from engineers to buyers — still confuse zinc-plated bolts with hot-dip galvanized (HDG) ones, assuming “coating is coating.”
It’s not. Let’s break it down.
🔍 Zinc-Plated Fasteners – For Controlled Environments
Process: Electroplated thin layer of zinc (~8–12 microns)
Appearance: Smooth, bright finish (silver/golden)
Use Case: Indoor or low-moisture environments (e.g., appliances, furniture, electronics)
Caution: Will rust quickly in outdoor or high-humidity conditions
Verdict: Great for aesthetics and light-duty, but not for outdoors.
🔨 Hot-Dip Galvanized (HDG) Fasteners – Built for Harsh Duty
Process: Fastener dipped in molten zinc (~40–85 microns coating)
Appearance: Matte grey, rougher finish
Use Case: Construction, infrastructure, marine, wind, solar, bridges — where corrosion resistance is critical
Caution: Requires matching HDG nuts due to thicker coating
Verdict: More expensive, but the right choice for long-term protection outdoors.
⚠️ What Happens When You Choose the Wrong Finish?
✅ Corrosion starts silently
✅ Structural joints weaken
✅ Entire assemblies may need rework
✅ Warranty claims skyrocket
✅ Brand reputation suffers
The wrong coating doesn’t just cost money — it destroys trust.
🛠️ Why This Knowledge Is Mission-Critical in Fastener Sales
Most salespeople in fasteners talk price.
Few talk coating compatibility, life expectancy, torque loss, or environmental match.
That’s the difference between a vendor and a trusted supplier.
And that’s exactly what we train at Arslok.
