If you work with pop rivets or rivet nuts even occasionally, this little red gauge is about to become your new best friend. It's a super handy tool that lets you quickly identify the size of a rivet without guessing or digging through manuals. Here's what it measures: Pop rivet diameters from size 3 (which is 3/32 inch) all the way up to size 8 (1/4 inch). It also checks the trade size or grip length of blind rivets, covering sizes from 32 through 816. Plus, it has slots for measuring rivet nuts, from #6 up to 3/8 inch. It's made from a solid 1/4-inch thick piece of hard plastic (in a bright red color so it's easy to spot in your toolbox), and it's about 5-3/8 inches long by 3-3/8 inches wide. It's durable, simple to use – just see which slot your rivet fits into snugly – and it saves you from using the wrong size rivet for a job. Whether you're in automotive repair, metalworking, HVAC, or just a serious DIY enthusiast, this gauge eliminates the headache of sizing. It's a must-have tool that doesn't cost much but delivers a ton of value in accuracy and convenience. Throw it in your kit and thank yourself later.
