BS ISO 8788:2020

What is ISO 8788 about?  

ISO 8788 is an international standard on metric nuts that discusses the tolerances required for manufacturing precise metric nuts.  

ISO 8788 defines the tolerances of form and position of metric nuts meant for aerospace construction. These tolerances comply with ISO 1101, ISO 2692, and ISO 5459. 

Who is ISO 8788 for?  

ISO 8788 on metric nuts is relevant to: 

• Manufacturer of metric nuts 
• Aerospace industry  

Why should you use ISO 8788? 

Tolerance is the permissible limit or limits of variation in a physical dimension; a measured value or physical property of a material manufactured object, system, or service in mechanical engineering the space between a bolt and a nut or a hole, etc. 

ISO 8788 provides guidance on types of nuts, illustration of tolerances of form and position, values. 

As a user of ISO 8788, you can be ensured of the tolerances of form and position of metric nuts. With obedience and compliance to ISO 8788, you can efficiently manufacture high-quality metric nuts of precise dimensions. ISO 8788 helps you to build consumer trust and confidence in the product. With ISO 8788 you can be ensured that the products consistently meet and exceed quality assurance targets.
