Close enough, but not quite right.
by Cory from Concord, Massachusetts on August 11, 2016
It would have been really helpful if the description on the website had indicated the thread information. These thumb screws were NOT a perfect match for the Bimini hardware I already had attached to my boat, but they were close enough that they are getting the job done.

Discovery Dave
by David from Lexington, South Carolina on August 04, 2013
This Thumb Screw was a perfect fit for mounting my Sunbrella bimini to the factory installed side panel glass bracket. This appears to be a somewhat standard thread. Application was on a 1997 Chris Craft Ultra Concept 21.
