What is ISO 15787?

ISO 15787:2001 is officially titled:

“Fasteners — Marking and labelling”

The standard specifies marking requirements for fasteners, especially high-strength fasteners with full-load capacities, to ensure:

  1. 🆔 Identification of manufacturer or responsible party
  2. 🔩 Grade and property class
  3. 🧾 Lot or batch traceability
  4. 🗂️ Clarity in product documentation and labelling

Fasteners covered under ISO 15787 include:

  1. Hex bolts and screws
  2. Studs
  3. Cap screws
  4. Nuts and similar threaded components

While ISO 15787 was initially released in 2001, it is still referenced globally as part of product quality assurance and traceability programs, especially when aligned with ISO 898, ISO 965, and other fastener standards.

Why is ISO 15787 important?

Incorrect or missing fastener markings can lead to:

          ❌ Mismatched parts in critical assemblies

          ⚠️ Safety failures in load-bearing applications

          💸 Non-compliance with customer or regulatory specifications

          🔍 Challenges in tracing defective batches or conducting recalls

ISO 15787 eliminates ambiguity by providing a standardized way to mark fasteners with all critical identification information.

What are the benefits of ISO 15787?

Implementing ISO 15787 enhances the reliability, usability, and traceability of mechanical components:

  1. Standardized Fastener Identification

          Ensures fasteners are marked consistently with property class, origin, and specification.

  1. Lot Traceability

           Enables manufacturers to trace back issues to specific production batches.

  1. Improved Quality Assurance

          Supports inspections, audits, and compliance documentation.

  1. Minimized Risk of Product Failure

          Prevents the use of incorrect or counterfeit fasteners in critical systems.

  1. Compliance with International Supply Chain Requirements

          Accepted by OEMs, Tier 1 suppliers, and regulatory bodies worldwide.
