Fastener Standards

This page provides a sortable reference list of widely used fastener standards across ISO, DIN, EN, BS and ANSI/ASME systems. FastenerFix‑stocked standards are highlighted for quick identification. The table covers bolts, screws, nuts, washers, pins, keys, rivets, threaded rod, thread forms, structural fasteners, coatings and general fastener terminology.

Important Note: Standard numbers are not globally unique. Identical numerics may appear in ISO, DIN or EN standards while referring to completely different products, particularly when the standards originate from unrelated technical domains (for example, fasteners versus textiles or metrology). Even experienced engineers often assume these numbers are unique, but the compilation of this data resource has highlighted just how misleading that assumption can be. Each entry is therefore identified by its full standard designation, not by number alone.

Did you know?

The number 4035 appears in multiple standards systems but refers to completely different products depending on the issuing body. For example:

  • ISO 4035 / DIN EN ISO 4035 – Hexagon thin nuts (fasteners)
  • DIN EN 4035 – Aerospace rod end with self‑aligning double‑row ball bearing
  • SAE AMS 4035 – Aluminium alloy sheet and plate (materials specification)
  • SAE MA 4035 – Spiral‑wound retaining rings (mechanical components)
  • JIS E 4035 – Railway rolling stock temperature test methods

Same numerics, entirely different engineering domains. This is why FastenerFix identifies each entry by its full standard designation, not by number alone.
