Bolt Standards

Bolt Standards — Ensuring Quality, Strength, and Consistency

The Bolt Standards guide from Allfast Solutions NZ explains how fasteners are measured, tested, and certified for safety. Understanding bolt standards helps you choose the right product every time, ensuring your work meets both local and international requirements.

These standards define everything from thread pitch and tensile strength to material composition and coating. As a result, they play a crucial role in maintaining reliability across construction, manufacturing, and engineering projects. When you know the standards behind each bolt, you can order, install, and inspect with confidence.

Our Bolt Standards page covers:

• The most common international standards and what they mean

• Strength grades (4.6, 8.8, 10.9, 12.9) and how they compare

• Metric vs. imperial bolt classification systems

• Surface coatings and corrosion-resistance requirements

• Testing procedures and quality assurance guidelines

• Practical tips for choosing compliant fasteners

Furthermore, the guide explains how different standards align across global systems, such as ISO, DIN, ASTM, and AS/NZS. This comparison makes it easier to substitute or source equivalent products without compromising on performance or compliance. In addition, the tables and charts are formatted for quick reference, allowing tradespeople to find information at a glance.

At Allfast Solutions NZ, we take standards seriously because precision and safety depend on them. Therefore, we supply fasteners that meet or exceed recognised specifications, giving you peace of mind on every project. Our team is also available to help interpret these standards, ensuring you always get the correct bolt for your application.

For a deeper understanding of international classifications, visit the International Organization for Standardization (ISO). There you’ll find detailed information on the testing and grading systems used worldwide.

In summary, this Bolt Standards guide brings clarity to a technical topic. It helps you work smarter, stay compliant, and build with confidence — every single time.
