Clamping length specification:For blind rivets with smooth rivet shafts and head types A, B, C or similar, thesuitable nominal length can be set according to the rule of thumb:Clamping length (material thickness) + 1 x rivet nom. Ø = rivet nominal length min.*(* For interim results, the next-largest rivet length is to be chosen)
The allocation of the rivet nominal length according to clamping length/materialthickness differs minimally for standard blind rivets - between standardspecifications (DIN 7337, attachment A and B) and factory specifications - according to various material combinations.
Rivet hole/Drill diameter:For blind rivets of the types A, B or C corresponding or similar to DIN 7337 as wellas for "CAP" and "PolyGrip" multi-section blind rivets, the rivet/drill hole diameteris specified according to the following rule of thumb:Rivet nom. Ø: d1 + 0.1 mm (tol. +0.1mm) = Rivet hole/Drill hole Ø D3
The following applies for blind-rivet nuts:Shaft Ø: d1/wrench size + 0.1 mm = Drill/Punch/Hole Ø D3
