Pack of 4 low-profile head saves weight while providing appropriate clearance for the bottle. The flange head better distributes load across nearly 3x more surface area than a cap screw and more than 2x the surface area of a button head providing both increased rigidity and lower stress.
Each screw is machined complete in one operation from 6Al/4V Titanium on a Swiss Lathe. Â Threads are roll formed for peak strength and material grain alignment in the finished screw.Â
