Fasteners: FAQ

How do I ensure the thread pitch matches my project requirements?

Always verify if the listing uses Metric (M) or Imperial (UNC/UNF) standards. Consult the seller's technical diagram to confirm the exact pitch in millimeters to avoid stripping threads.

How can I verify if the material is truly rust-resistant?

Look for specific material grades like SUS304 or SUS316 in the specifications. SUS316 is the industry standard for marine and high-moisture environments, offering superior corrosion resistance.

What specs indicate a high-strength bolt for heavy loads?

Check the property class rating stamped on the bolt head; ratings like 8.8, 10.9, or 12.9 indicate high-tensile carbon steel suitable for structural or automotive use.

Will small hardware items be packaged securely for international transit?

Reputable sellers use thick poly-bags or plastic compartmentalized boxes. For better security, select 'AliExpress Standard Shipping' to ensure tracking and consolidated packaging.

Recommendations for buyers

✓
Material Grade Selection
Select materials based on environment: Zinc-plated for dry indoor use, Stainless Steel for moisture, and Titanium for high-strength, low-weight needs.
✓
Standard Compliance
Ensure the fasteners meet international standards such as DIN, ISO, or ANSI to guarantee compatibility with existing tools and components.
✓
Surface Coating Quality
Check for advanced finishes like Black Oxide, Dacromet, or Hot-Dip Galvanizing to extend the lifespan of the hardware in harsh conditions.
✓
Bulk Lot Optimization
Fasteners are most cost-effective when purchased in 'Lots'. Compare the price-per-piece across different quantity options (e.g., 10pcs vs 100pcs).
