Solid aluminium rivets DIN 660 — 4 × 12 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 × 12 mm denotes a nominal shank diameter of 4 mm and a length of 12 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: 6 mm
- Thickness of joined components s — form B: 9 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.
