The butt fastener assembly is comprised of a bolt and two cams. The butt fastener connects profiles end-to-end and provides a clean, flush connection, especially convenient where space restrictions apply. The butt fastener can also be used to connect shorter bars together where logistics or space makes it difficult to maneuver longer profiles. This connection method requires a counterbore machining service on each profile. TIP: Butt Fastener Machining will need to be added to the profile when ordering.
