Thanks so much for your reply & info.1/8" or 3/16" diameter by 1/4" long, diameter depending on the eye strap. You can use SS but are better off with the typical aluminum. The SS if using on salt water will create corrosion with the aluminum and the aluminum will breakdown faster.
That will probably work. A longer pop-rivet will have no penalty, unlike the trim pop-rivets.I want to change the aft mainsheet block on my boom to one that swivels. What size rivet is used on the eye strap?
Looks like maybe 1/8"x 1/8" SS?
