Open Rivets

Open rivets are a dependable choice for manufacturers that need fast, consistent blind fastening in sheet metal, panels, brackets, housings, covers, and other assembled components. Also commonly searched as open end rivets or open end blind rivets, this rivet style is widely used when the back side of the joint is difficult to reach and a clean, efficient installation from one side is important.

PENCOM’s Open Rivets category includes several head styles to match different assembly needs. ROA Open Dome Rivets are a general-purpose solution for sheet assemblies and are a good fit when a slightly raised finished head is acceptable. ROB Open Large Dome Rivets use a wider flange to increase bearing area, making them a strong option for thinner or softer materials and applications where improved pull-through resistance and a neat finish matter. For designs that need a smoother outer surface, PENCOM also offers ROC Open Countersunk Rivets, ROC Open 100 Degree Countersunk Rivets, and ROC2 Open 120 Degree Countersunk Rivets.

Choosing the right open blind rivet often comes down to head style, material thickness, and finish requirements. Dome head rivets are a practical option for everyday fastening across trays, covers, and brackets. Large dome rivets are often selected when more surface support is needed on plastics, thin sheet, or materials that can deform more easily. Countersunk rivets are preferred when the rivet should sit low and preserve clearance for mating parts, sliding components, guards, labels, or gaskets. The 100 degree and 120 degree countersunk options help match the fastener to the countersink profile specified in the design.

Because these are blind rivets, they help simplify assembly in closed sections, channels, enclosures, and other builds with limited backside access. When selecting an open rivet, it is important to review the required grip range, rivet diameter, head style, and material combination so the installed joint matches the thickness and demands of the application.

If you need open end blind rivets for general sheet metal fastening, wider-bearing large dome applications, or flush countersunk installations, PENCOM offers a practical range of options to support production, prototyping, and ongoing supply requirements.
