Set of four gauges for -3,-4,-5,&-6 rivets.
Each gauge measures MINIMUM height and MINIMUM diameter of shop heads AFTER setting. Eliminates guessing if your rivets are properly set. Works for measuring both universal head and flush rivets. Precision machined to size from 2024 aluminum. Rivet size permanently stamped on each gauge. Color coded anodized finish.
I bought this as a recommendation from another student in my sheet metal class. I am so glad I did. My rivets improved overnight and the tool has made such a difference. Honestly this is some of the best $20 I have spent in a long time. If you are planning on doing fabrication work or rivet inspection in your career, this will be a godsend and save you a lot of time.
Aviation Instructor, used during structures, very nice addition to the schooling tools for this course.
A small investment to make if youre about to place 10,000 rivets. Very easy to check the diameter and height of your shop heads.
Use to check students rivets for proper size. Works well.
