You might be surprised to learn that the industrial marketplace is filled with hundreds of registered trademark-branded expensive fasteners and components that have generic alternatives. Just as brand-name pharmaceuticals like Tylenol and Advil are available generically as acetaminophen and ibuprofen, certain brand-name fasteners can also be found as “generics,” “cross-references,” “alternatives,” or “functional equivalents.”
What Are Functional Equivalent Fasteners?
In the world of fasteners, a functional equivalent fastener is a part that matches the brand-name product in form, fit, and function, including material and plating specifications, but is manufactured by an alternative company. Hence, the industrial marketplace is home to hundreds of fasteners and components that are registered under various trademark brands, but that offer the same function. This ensures you receive the same product performance and quality at a potentially lower cost and with shorter lead times.
What OEM Brands Have Generic Functional Equivalent Fasteners?
Many OEM brands have generic functional equivalents. Below is a comprehensive list of brands that have generic alternatives:
3 STAR RIVETS USA, ABBATRON®, ALCOA, AMATOM®, APEX®, ARCONIC®, ATLAS®, AVDEL®, AVK®, B. F. GOODRICH, BOLLHOFF, BUCKEYE, CAPTIVE, CELUS®, CHERRY®, CONCORD, FASTENAL, GESIPA®, GRIPCO®, GLOBE ELECTRONICS, H. H.

S. ANCHOR. VIP, W. M. BERG, W. W. GRAINGER, WALDES TRUARC®, UNICORP.
Do Standoffs and Spacers Have Functional Equivalents?

In fact, standoffs and spacers are sometimes referred to by their brand names, which can often be substituted by generic equivalents. Popular brands include: Amatom®, Concord, Globe, H.H. Smith, Lyn-tron, Microplastics, Keystone, Pem®, RAF, Unicorp. Their equivalents are available in a range of types, materials, sizes, and specifications.
