Product Description
Product Description & Key Specifications
Open-end dome-head blind rivets are the most widely used general-purpose blind rivet type. Installation is completed entirely from one side, making them suitable for sheet, tube, panel and enclosure assemblies where the rear face cannot be reached.
During installation, the rivet tool pulls the steel mandrel through the aluminum body. The body expands and forms a blind-side bulb; once the intended setting load is reached, the mandrel breaks at its designed break point and leaves a permanent joint without a separate nut.
Correct selection depends on rivet diameter, body length, grip range, hole diameter, head style, material combination and required shear or tensile load. Diameters 3.2, 4.0, 4.8 and 6.4 mm are common for sheet-metal panels, automotive trim, railway interiors, HVAC ducting, enclosures and light fabrication.

Selection
Selection Advantages by Application
Automotive Panels and Light Covers
Al/St blind rivets are used for covers, brackets, trim and light channels where assembly-line speed and one-side access are important.
Automotive and EV fastenersRailway Panels and HVAC Systems
Blind rivets allow one-side installation of interior panels, air ducts and service covers. Vibration, grip range and joint load should be confirmed for critical projects.
Railway fastenersLight Fabrication and Construction Equipment
Diameters 4.0-6.4 mm are common in enclosures, guards, signs and fabricated brackets that need fast permanent fastening without welding or a rear nut.

FAQ
Common Questions Before RFQ
What is an open-end blind rivet?
It is a permanent two-piece fastener installed from one side. The tool pulls the mandrel to expand the rivet body behind the sheet, then the mandrel breaks when setting is complete.
How do I select rivet length and grip range?
Add the thickness of every layer being joined, then select a rivet length whose published grip range includes that total thickness.
Which blind rivet diameters are most common?
Diameters 3.2, 4.0 and 4.8 mm are widely used for general sheet metal; 6.4 mm is used when the design requires a larger joint.
Can these rivets be installed without rear-side access?
Yes. That is the primary advantage of blind riveting: the complete setting operation is performed from the front side with a suitable rivet tool.
What information is needed for an RFQ?
Send diameter, length or grip range, panel thickness, hole diameter, head style, material combination, required shear or tensile load and quantity.
Need open-end blind rivets for sheet-metal assemblies?
Send diameter, length or grip range, total thickness, hole diameter, head style, material combination and quantity. We can quote Al/St blind rivets from 2.4 to 6.4 mm to DIN 7337 / ISO 15977.
