SAE AS Aerospace 3D CAD Fastener Library

CERTIFIED 3D CATALOG

SAE-AS Aerospace Standards

SAE AS is an aerospace standard developed by SAE International, comprising more than 8,500 active standards. It is intended for aerospace and other mobility applications in high-stress environments.

Certified native CAD models of the SAE AS standard are available in partnership with CADENAS USA.

CERTIFIED 3D CATALOG

AIA-NAS Aerospace Standard

The NAS Parts Library is an aerospace standard developed and managed by AIA, with more than 1,400 active standards. It is intended primarily for aerospace applications, but is also used in other high-stress environments.

CADENAS USA has partnered with AIA to offer the full NAS Parts Library as certified native CAD models for engineers.

ASME B18.24 3D CAD Fastener Library

CERTIFIED 3D CATALOG

ASME B18.24 Standard

ASME and CADENAS USA partnered to create ASME B18.24 PIN code lookup software. With the ASME B18.24 PIN code, users can identify any ASME B18 fastener configuration and download a PDF spec sheet or certified CAD model.

The ASME B18.24 standard assigns a unique PIN code to every possible configuration within the ASME B18 fastener standard, helping engineers and manufacturers ensure the correct part is specified and produced.
