Fastenal Engineering

Our team of degreed engineers and quality lab technicians can provide the information and expertise you need to make the best possible fastener selection, usage, and design decisions. We were among the first in the industry to implement full product traceability (years before the Fastener Quality Act). We’ve been ISO quality registered since 1994, and we received our first A2LA lab accreditation in 1998. Today our tradition of quality continues with industry-leading systems.

Technical Expertise

Our knowledge of the industry standards, fastener technology, and fastener materials ensures an accurate and timely response to virtually any fastener related question.

Most fasteners are made to comply with one or more standards. The Fastenal Engineering & Design Support group are members of ASTM, ASME, and ISO and are actively involved in the development of standards. Some of the many organizations that write fastener standards are:


In addition to providing QC testing for Fastenal products, our in-house A2LA accredited lab is equipped to provide our customers with complete mechanical and chemical fastener analysis. Product testing is conducted to internationally recognized standards (including ASTM, SAE, ASME, ISO, and DIN) as well as customer required specifications.
