Type 304 Stainless Steel Rivets. Yes, really!
The caps are 9.3mm. They are thick enough to be fiber laser engraved and are durable and secure. Of course any rivet is only secure if it’s properly set. These do NOT have brass shafts, they are 100% Stainless Steel so they require more force to set (which is also why they do not come apart by even the strongest dog’s lunge).
Perfect for 2 layers of Super Heavy Weight Biothane or 3 layers of Standard Weight Biothane.
Standard Weight is is .095″ – .105″ thick. Super Heavy Weight is .14″ – .16.” thick.
The shaft on these Stainless Steel Rivets is 11.5mm long. They will fasten materials that have a total thickness from .28 to .32 inches.
You should choose shorter shafts for 2 layers of Standard Weight Biothane .

You should choose longer shafts for 3 layers – 2 layers of Standard Weight Biothane plus 1 layer of Super Heavy Weight Biothane.

If you have a press, use a 9mm or 10mm Rivet Die. It must be ROUNDED, or you will flatten the beautiful smooth rounded tops and bottoms. Please see the picture above of the dies I use.
These rivets require more force to set than plated or brass rivets. Stainless steel is a harder metal and not as malleable. More difficult to set but much more durable and strong once set.
Be advised… these are truly permanent fasteners. Trying to remove them without mangling your material is not likely!
