Fastener Materials
Compare strength, corrosion resistance and cost across the materials we manufacture every day.
| Material | Grades | Strength | Corrosion | Relative Cost | Best For |
|---|---|---|---|---|---|
| Carbon Steel | 4.8 / 8.8 / 10.9 | 400 - 1000 MPa | Poor (needs plating) | $ | General-purpose, furniture, machinery, construction |
| Stainless Steel 304 | A2-70 / A2-80 | 700 - 800 MPa | Excellent | $$ | Food, pharmaceutical, outdoor, marine-adjacent |
| Stainless Steel 316 | A4-70 / A4-80 | 700 - 800 MPa | Superior | $$ | Coastal, chemical plants, harsh chloride environments |
| Alloy Steel | 10.9 / 12.9 | 1000 - 1200 MPa | Poor (needs coating) | $ | Heavy machinery, engines, structural bolting |
| Brass | H62 / H65 | 300 - 500 MPa | Good | $$ | Plumbing, electrical terminals, decorative hardware |
| Aluminum | 6061 / 7075 | 250 - 500 MPa | Good | $$ | Aerospace, electronics, outdoor gear, lightweight assemblies |
* Strength values are indicative tensile ranges. Exact properties depend on grade, heat treatment and standard (ISO / DIN / ASTM).
Expert Material Insights
Carbon Steel
The workhorse. Always pair with zinc, galvanizing or Dacromet finish.
Stainless Steel 304
Most common stainless. Resists rust without plating.
Stainless Steel 316
Adds molybdenum for maximum corrosion resistance.
Engineering Decision Tip
"Most fastener failures aren't due to poor material, but poor pairing of material + finish for the target environment."
