Quality Control
Quality Control
At Crystal Fasteners, quality begins at the very foundation — our raw materials. We source exclusively from Tata Steel Limited, a globally renowned leader known for uncompromised product excellence. This ensures every nail is manufactured from premium-grade steel with consistent strength and reliability.
Our philosophy is simple: quality at every stage. From raw material checks to the finished goods, every batch undergoes strict quality control to meet international standards. We have an in-house testing lab where nails are subjected to multiple rigorous inspections, including:
- Visual Inspection – to eliminate surface defects.
- Length & Diameter Measurement – ensuring dimensional accuracy and consistency.
- Tensile Strength Testing – validating load-bearing capacity.
- Surface Finish & Coating Check – confirming smoothness and protective finishing.
- Corrosion Resistance Testing – assessing durability in challenging environments.
- Impact Testing – ensuring toughness under stress and shock.
In addition to product testing, we emphasize process testing — ensuring every manufacturing step complies with prescribed quality standards. For clients with specialized needs, we also provide customized testing solutions tailored to unique applications and requirements.
Testing Process
Our advanced testing process ensures precision, safety, and long-term performance in every nail we produce. Comprehensive tests include:
- Tensile Test – measures strength and resistance under load.
- Torsion Test – evaluates twisting resistance and flexibility.
- Elongation & Breaking Load – determines durability and breaking point under extreme stress.
- D.C. Resistance – ensures electrical compliance where applicable.
- Lay Length & Uniformity of Zinc Coating – confirms protective coatings meet global standards.
- Overall Diameter & DIP Test – ensures dimensional consistency and coating thickness.
- Strand Breaking Load – checks overall structural strength for heavy-duty applications.
Through these extensive controls, Crystal Fasteners guarantees performance, safety, and reliability — making us a trusted partner in the global fastener industry.
ICC-ES Certified Strength You Can Trust
Crystal Fasteners collated nails are ICC-ES ESR-5574 certified and independently validated for structural performance and code compliance. These nails meet International Building Code (IBC) and International Residential Code (IRC) standards for strength, durability, and safety. Designed for engineered and prescriptive wood-to-wood structural connections, they deliver reliable performance in shear walls, diaphragms, and braced wall systems. Manufactured to strict ASTM material and dimensional tolerances, they are available in smooth, ring, and screw shank options with multiple protective coatings. Each product is quality-controlled and verified under ICC-ES inspection standards. Suitable for residential and commercial construction, they ensure strong, long-lasting fastening performance.
