Many branded parts have generic alternatives. Similar to how brand-name products like Kleenex® can be found generically as facial tissues, many brand-name fasteners are also available as “generics,” “crosses,” “alternatives,” or “functional equivalents.”
Functional Equivalent Fastener? What is it?
In the fastener industry, a functional equivalent fastener is a part that replicates the brand-name product in form, fit, and function, including material and plating specifications, but is produced by a different manufacturer. This allows you to get the same performance and quality, often at a lower cost and with shorter lead times.
Which OEM Brands Have Functional Equivalent Fasteners?
A significant number of OEM brands out there have generic functional equivalents. Here is a shortlist 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®, GLOBE ELECTRONICS, GRIPCO®, H. H. SMITH, HELICOIL®, HOWMET, HUCK, INDUX, INTERFAST, KATO®, KEENSERT®, KEYSTONE, LOCTITE®, LYN-TRON, MACLEAN ESNA®, MARSON®, MCMASTER-CARR, MISUMI, MSC INDUSTRIAL, PEM®, PIC DESIGN®, POP®, POWERS®, QUICKSCREWS, RAF, RECOIL®, RED HEAD®, ROTOR CLIP®, SHEREX, SIMPSON, SOUTHCO®, SPS TECHNOLOGIES, TINNERMAN®, U. S. ANCHOR, UNICORP, VIP, W. M. BERG, W. W. GRAINGER, WALDES TRUARC®.
Do Helical Inserts Have Functional Equivalents?
One example of an OEM hardware brand is the trademarked name Helicoil®. Although the name Helicoil® is often used to refer to helical inserts (also known as helical wire, wire inserts or wire threaded inserts)—similar to how Band-Aid® is used to describe adhesive bandages, Helicoil® is the registered trademark of Stanley Engineered Fastening (recently acquired by Bollhoff).
The same helical inserts manufactured under the Helicoil® brand name are also available from alternative manufacturers under brand names such as CHRISLYNN, Recoil®, and KATO®, E-Z Lok and Powercoil. These inserts can also be identified by their Mil-Spec numbers, which include: MS122076 through MS122275, NAS1130, MS124651 through MS124850, MS21208, MS21209, MS122076, MS33537, MA3279, MA3329, and NA0276 series. Note: All of these offerings are the tanged version of helical inserts.
