Tubular rivets are manufactured from precision capillary tubes. They are produced according to DIN 7340 standard and are ideal fastening elements for various applications. Our hollow rivets made to DIN 7340 standard are crafted with the highest precision to meet the requirements of technically demanding projects. Dedicated machines are required for production.
In Rona Kranj we offer the following versions:
"A" type head form: tubular or hollow rivet with a flat head. This version of the sleeve has a flat top and is made from drawn precision tube. Compared to conventional hollow sleeves, these rivets have the advantage of both the inner and outer diameters on the stem being precisely cylindrical and having the same wall thickness.
"B" type head form: tubular or hollow rivet with a formed round head. The head of the rivet is shaped by a former. This version is especially suitable if specific requirements regarding the shape of the head are desired.
"C" type head form: tubular or hollow rivet with a formed countersunk head. These so-called bushings with a countersunk head are suitable for projects requiring a flat surface. This design facilitates surface processing and ensures seamless integration.
We manufacture the following dimensions of tubular rivets:
- External diameter of the stem: 1mm – 15 mm
- Wall thickness: 0,15mm – 1mm
- Length: up to 200mm
Dimensions and tolerances are determined by the DIN7340 standard:
