Solid aluminium rivets DIN 660 — 4 × 8 mm, round head, 50 pieces
Uncoated solid aluminium rivet with a factory-formed round head and a solid cylindrical shank. The joint is made by riveting the free end of the shank. The size 4 × 8 mm denotes a nominal shank diameter of 4 mm and a length of 8 mm measured under the head. The technical data sheet specifies DIN 660 and reference PN 82952.

For the aluminium version, the data sheet specifies Al 99,5, minimum strength Rm 100 N/mm² and the material standard DIN 1769-1. These are catalogue requirements in the data sheet, not a test result for this batch, a material certificate or a permissible load for the finished joint.
Installation dimensions according to the technical data sheet
Form A denotes a round closing head after riveting; form B denotes a conical closing head after riveting. These are two ways of forming the free end of the rivet. They do not change the factory-formed round head. The s values apply separately to each form, rather than to a common thickness range.
- Installation hole d7: 4,2 mm
- Hole tolerance d7: H12
- Thickness of joined components s — form A: 3 mm
- Thickness of joined components s — form B: 5 mm
- Closing head diameter d8: 7 mm
- Closing head height k1 — form A: 2,4 mm
- Closing head height k2 — form B: Approximately 1,9 mm
- Depth t1 — form B: 1,8 mm
Selecting the rivet and riveting method requires consideration of component thickness, hole preparation and the tools used. Tolerance designations from the data sheet are given; no unconfirmed numerical length deviations have been added.
