What This Rivet Does
This blind rivet joins materials when you can only reach one side of the joint. The tubular body and central mandrel are inserted into a pre-drilled hole, and a rivet tool pulls the mandrel to expand the tail before it snaps off. It suits maintenance, fabrication and automotive repair tasks where rear access is blocked.
Installation Load and Tool Force
The aluminium body deforms with moderate hand-tool pressure, keeping operator effort low and avoiding damage to thin sheets. No heat, sparks or electrical power are needed, so the process is quiet and safe for indoor or roadside work. The mandrel breaks cleanly at the designed point, leaving a flush dome head.
When to Choose a Different Fastener
Buyers needing a water-tight seal, structural shear ratings, or a countersunk finish should select a specialised rivet type instead. This dome-head aluminium rivet is not intended for high-vibration critical joints or applications requiring stainless or steel mandrels. Larger grip ranges or different diameters are not covered by this part number.

Questions about this item
How do I install the 51070 blind rivet and what step is often missed?
Drill a 1/8 in hole through both parts, insert the rivet from the accessible side, then use a rivet gun to pull the mandrel until it snaps; the step often missed is confirming the mandrel has fully broken off before releasing the tool.
What maintenance or replacement will the 51070 rivet need later?
The rivet is a permanent fastener; no maintenance is required, but if the joint loosens the rivet must be drilled out and replaced with a new one.
What limit appears first on the 51070 rivet under sustained vibration?
The clamped joint can lose preload over time, causing the rivet to work loose; this joint relaxation is the first limit under sustained vibration.
