Ingco 250pc Open End Rivet Set, 4.8 x 12mm, Model HRT04812

Our review

This is a 250-piece set of open end rivets from Ingco, sized 4.8mm in diameter by 12mm in length, with a head diameter of 9.5mm. The model number is HRT04812. Open end rivets like these are the standard choice for joining sheet metal, plastic, and similar materials where you want a firm, permanent hold and access from only one side. The 250-piece count makes the set practical for anyone doing repeated work rather than a one-off repair, such as fabricators, workshop technicians, or someone assembling panels and ducting regularly. Before buying, check two things: that your rivet gun or riveter accepts 4.8mm rivets, and that the combined thickness of the materials you are joining falls within what a 12mm rivet can grip. The summary notes these rivets are intended for use with certain Ingco tools, specifically items HR171, HR211, HR104, HR101, and HFOR321, so if you already own one of those, compatibility is straightforward. Compared with other rivet sets, the main differences you will see are material, diameter, length, and head style. Open end rivets leave the mandrel stem inside the body after setting, which is normal and fine for most general fixing jobs. If you need a sealed or watertight joint, you would look at closed end rivets instead. Also compare pack sizes, since a 250-piece set suits frequent use, while smaller packs may be enough for occasional repairs. Check the rivet length against your material thickness before committing, as too short a rivet will not grip and too long a one can leave a loose joint.
