Bolt Dimensions

The Bolt Dimensions guide from Allfast Solutions NZ helps you choose the right bolt for every job. It’s a simple, accurate reference that covers the key dimensions, thread sizes, and material options used across New Zealand’s trade and construction industries.

Knowing your bolt dimensions means you can match fasteners precisely to the task. The guide lists common measurements such as diameter, thread pitch, and length, plus recommended washer and nut pairings. Whether you’re working on timber framing, structural steel, or mechanical assemblies, this resource saves time and reduces guesswork.

Our Bolt Dimensions page includes:

• Standard metric and imperial sizing charts

• Head styles and their applications

• Thread pitch and tolerance information

• Material grades like stainless, galvanised, and zinc-plated steel

• Quick conversion between millimetres and inches

• Helpful notes on bolt identification and markings

Each table is clear, compact, and designed for fast referencing on site or in the workshop. Every measurement follows recognised industry standards to ensure compatibility across tools, equipment, and fixings.

At Allfast Solutions NZ, we believe reliable fastening starts with accurate information. That’s why we supply not only the products but also the knowledge to use them correctly.
