The double anchor fastener assembly is comprised of two socket head cap screws, two cams, and a double T-nut. This design doubles the contact between the fastener and mating profile, making an extremely strong connection. The fastener provides infinite positioning along the mating profile‚Äôs T-slot, allowing a large degree of adjustability. The double anchor fastener provides 90 degree, flush, vibration resistant connections, especially convenient where space restrictions apply and is used for profiles with open T -slots opposite each other. 80/20 recommends the double anchor fastener for non-column loaded supports to add extra strength. This connection method requires a counterbore machining service on the mounting profile. Additional Information: Cams are available separately for instances where you want to create your own custom assembly.
