Product and application brief
A solid rivet is a headed, unthreaded part with a solid shank rather than a tubular cavity or a separate pull mandrel. Round and countersunk heads are different product forms. Define the uninstalled blank and the joint requirements separately: the manufactured head and smooth tail shown here are not an installed two-head assembly.
Product forms and reference names
| Product form / field | Reference and distinguishing details |
|---|---|
| Round head — DIN 660:2012-01 | Official DIN catalogue identity for round-head rivets with nominal diameters within its stated 1–8 mm scope. This scope is not our size or stock list. |
| Countersunk head — DIN 661:2011-03 | Separate DIN identity for countersunk-head rivets within the stated 1–8 mm nominal-diameter scope. The head seat and length datum must match the selected drawing. |
| Bossard BN 690 / BN 691 reference forms | The original solid-rivet catalogue separates round-head DIN 660 from flat countersunk DIN 661. BN 691 is named as a 75° catalogue form; do not apply that angle to every countersunk rivet or infer brand supply. |
| Drawing-defined solid rivet | Other head profiles, lengths, materials or machined details require a controlled drawing and applicable reference. A custom shape is not automatically within the above DIN scopes. |
Solid shank, not a blind or tubular rivet
The solid cylindrical tail is a defining feature. A pull-mandrel blind rivet and a hollow or semi-tubular rivet have different constructions and product requirements. Do not reuse their grip tables or tooling assumptions for a solid rivet. A smooth unheaded pin is not identified solely by a similar shank diameter.
Manufactured head and length datum
Specify head diameter, height, underside or countersunk profile and the chosen length convention. Under-head and overall length descriptions are not interchangeable, especially across round and countersunk forms. Use the actual product drawing and its dimension symbols rather than assigning one length datum to all heads.
Blank length and joined stack are different
Joined thickness, hole specification, access and finished formed-head requirements belong to the joint definition. The amount of tail needed for forming depends on the selected material and process; no universal extra-length formula, setting force or installed load is specified here. Obtain the approved blank and joint drawing instead of selecting only by a nominal diameter.
Material and reference selection
Specify the metal, alloy or material designation and surface requirements independently from the head style. Bossard’s cited BN 690 and BN 691 pages show A2 stainless catalogue variants; that does not make every DIN 660/661 rivet stainless or establish our production conformity. Steel, stainless and nonferrous drawing-based requirements need their own material and forming acceptance evidence.
Specification fields
| Product form / field | Reference and distinguishing details |
|---|---|
| Reference and form | DIN designation and edition, maker code or controlled drawing; round/countersunk/other manufactured head. |
| Shank | Nominal diameter and the drawing-defined tolerance and straightness requirements. |
| Blank length | Length value, tolerance and measurement datum; uninstalled length separate from finished joint geometry. |
| Head geometry | Head diameter/height, bearing face or countersunk seat geometry from the selected reference. |
| Material and finish | Exact alloy/designation, material condition and permitted surface treatment. |
| Joint definition | Joined stack, hole requirement, access and formed-tail acceptance; process qualification if required. |
| Order definition | Quantity with units, drawing revision, inspection documents and packing requirements. |
Common product questions
Is a solid rivet interchangeable with a blind rivet?
No. A solid rivet has no pull mandrel; a blind-rivet sleeve and its setting system are a different construction. Identify the actual joint and product type.
Are DIN 660 and DIN 661 the same head form?
No. DIN 660 identifies a round-head family and DIN 661 a countersunk-head family. Head seating and length definitions must follow the selected drawing.
Can blank length or forming force be chosen from diameter alone?
Not from this overview. Joined thickness, material, product drawing and forming requirements must be specified separately; no universal tail allowance or installation force is promised.
