NASM 1312B is part of a series of National Aerospace Standards for material and fastener testing (originally stemming from military standards). It includes requirements for how tests like tension should be performed – including alignment criteria – especially for aerospace-grade fasteners and materials. If you work with aerospace components or contracts that reference NASM standards, you need to ensure compliance. The Alignment Device is built to satisfy the alignment accuracy called for in NASM 1312B, so it will help you meet those specifications. Even if you’re not directly using NASM methods, this highlights that the device meets very strict aerospace requirements, which is a good indicator of overall alignment quality.
