What is ISO 3269 - Fasteners about?
ISO 3269 is an international standard on fasteners that discusses the criteria for inspection of the quality of fasteners. ISO 3269 specifies an inspection procedure to be used by the purchaser where no prior agreement exists. ISO 3269 also specifies a reference acceptance procedure for acceptance or rejection of an inspection lot, when no agreement can be reached between the purchaser and the supplier, or where conformance to specification is disputed.
ISO 3269 applies to inspection lots of bolts, screws, studs, nuts, pins, washers, rivets, and other related fasteners.
ISO 3269 applies to fasteners not intended for high volume machine assembly, special-purpose applications, or specially engineered applications requiring more advanced in-process control and lot traceability.
NOTE: For in-process control or final inspection by the manufacturer and sorting, see ISO 16426.
Who is ISO 3269- Fasteners for?
ISO 3269 on fasteners is relevant to

Why should you use ISO 3269- Fasteners?
A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.
ISO 3269 navigates you through the incoming acceptance inspection procedures for fasteners, inspection modalities, acceptance inspection categories.
ISO 3269 exemplifies the required sampling plan and designated inspection categories that help you achieve precision in terms of product functionality. With obedience and compliance to ISO 3269, you can efficiently manufacture fasteners of precise dimensions. With ISO 3269 you can be ensured that the products consistently meet and exceed quality assurance targets.
What’s changed since the last update?
BS EN ISO 3269:2019 supersedes BS EN ISO 3269:2001, which is withdrawn.
The main changes compared to the previous edition are as follows:
- Introduction of an additional approach for incoming inspection with smaller sample sizes based on NA = 0
- Use of a reference approach in case agreement is not reached
- Sample size specified based on a lot size
- Addition of informative Annexes A and B explaining the basis for sample size selection
