EKINSUN is a custom parts manufacturer that makes rivets to drawing: solid and semi-tubular rivets turned in 316L, brass, copper, titanium or Monel in any length, blind rivets with a grip range or head the series skips, nameplate and eyelet rivets in odd sizes. The size ranges are those a distributor stocked in 2026.
A typical request: solid rivets 5 mm, 316 stainless, 38 mm long, round head, for a stainless gate, where stock stops at 25 mm and in 304.
Length and alloy: the two reasons a solid rivet is turned rather than bought.

Need rivets in a size, thread or material no catalogue lists? EKINSUN is a custom parts manufacturer: we make rivets to your drawing, sketch or sample, aluminium, steel, 304 stainless steel, copper or brass, from 1 piece, quoted in 12 hours and shipped duties paid. Standard sizes can often be supplied from stock; the more pieces, the lower the unit price. All custom fasteners
Grip range, hole size and setting
| Item | Rule | What goes wrong |
|---|---|---|
| Grip range | total thickness of the sheets must fall inside the rivet's grip range; ranges are stepped in the standard series | too short: the mandrel breaks before the tail forms; too long: the tail forms loose and the joint rattles |
| Hole diameter | rivet diameter plus about 0.1 mm (a 4.0 rivet in a 4.1 hole); drilled, not punched ragged | too large: the tail pulls through; too small: the body will not enter |
| Body and mandrel materials | aluminium / steel is general purpose; steel / steel and 304 / 304 for strength and corrosion; match the sheet to avoid a galvanic pair | an aluminium rivet in a stainless panel corrodes first |
| Head | dome for general use; countersunk for a flush face; large flange for thin or soft sheet | — |
| Sealed or open | open-end rivets leave a mandrel hole; sealed rivets do not | an open rivet on a tank or a housing leaks |
| Tool | hand, lever or pneumatic; nose piece matched to the mandrel | — |
Solid rivets have no grip range; the length is the sheet stack plus enough shank to form the second head, and the standards give that allowance per diameter. A solid rivet that is too long buckles; too short and the head is thin. This is why solid rivets are ordered by exact length and why a stainless gate with 38 mm of stack needs a rivet no catalogue lists.
Where the rivet catalogue stops
| What you need | In the catalogue? | What we make |
|---|---|---|
| Blind rivet 2.4–6.4 mm in aluminium, steel or 304, dome or countersunk, standard grip | Yes | Buy it from stock, or have it made to order from 1 piece. No one-off competes with a formed blind rivet. Standard parts: ask us too, we may have them in stock. |
| Solid rivet DIN 660 / 661 in the standard diameters and lengths, semi-tubular DIN 7338 2–8 mm | Yes | Standard sizes: buy them off the shelf, or have them made to order from 1 piece. Standard parts: ask us too, we may have them in stock. |
| A solid or semi-tubular rivet longer than standard, or in a diameter between sizes | No | Turned to length and diameter, from 1 piece. |
| A solid rivet in 316L, brass, copper above 8 mm, titanium or Monel | No | Turned in the alloy named. |
| A rivet head of your own shape: oval, pan, a large flat, a marked head | No | Turned or cold-formed to drawing. |
| A blind rivet with a grip range or a head the series skips, or in 316L | No | Sourced or made per batch; we say which. |
| A nameplate or eyelet rivet in an odd size or alloy | No | Turned or formed to drawing. |
| A structural aluminium 6061 or 7075 rivet | Partly | Solid aluminium rivets are standard in the common sizes in soft alloy; 6061 and 7075 rivets are turned on request for aircraft-style and light structural work, and we say which temper. |
Materials
| Material | Designation | Where it fits here |
|---|---|---|
| Aluminium | soft alloy for standard rivets; 6061 and 7075 to order | standard blind and solid rivets; light structures |
| Aluminium 6061 | AlMg1SiCu | turned solid rivets for light structural joints |
| Aluminium 7075 | AlZn5.5MgCu | turned high-strength light rivets, on request |
| Carbon steel | low-carbon, zinc plated | standard steel blind and solid rivets |
| Stainless 304 | 1.4301 / A2 | standard stainless blind, solid and semi-tubular rivets |
| Stainless 316L | 1.4404 / A4 | turned rivets for marine and chemical joints |
| Copper, brass | Cu-ETP, CW614N / CuZn37 | standard copper and brass solid, tubular and eyelet rivets; electrical |
| Titanium, Monel | Grade 2; NiCu30Fe | turned rivets for weight-critical and seawater joints |

Frequently asked questions
A blind rivet is set from one side: a tool pulls the mandrel, the body expands behind the sheet and the mandrel snaps. A solid rivet is a plain pin whose second head is formed by hammering or pressing from the far side, so both sides must be reachable; it is stronger and has no mandrel hole.
About 4.1 mm: the rivet diameter plus roughly 0.1 mm, drilled cleanly. The same rule holds for the other sizes; the maker's table gives the exact hole per rivet.
Measure the total thickness of the sheets to be joined, including any paint or gasket, and pick the rivet whose grip range spans it. Standard grip ranges are stepped; a stack that lands between two ranges needs a multi-grip rivet or a rivet made for it.
Yes. Solid and semi-tubular rivets are turned to any length and diameter in 304, 316L, copper, brass, aluminium 6061 / 7075, titanium or Monel, with round, countersunk, flat or special heads, from 1 piece.
EKINSUN is a custom parts manufacturer that turns and forms solid, semi-tubular, nameplate and eyelet rivets, and sources or makes blind rivets outside the standard series, in steel, stainless, copper, brass, aluminium and titanium, from 1 piece, with a quote within 12 hours.
No list price; the drivers are the alloy, the length, the head form and quantity. A batch of 316L solid rivets turned to 38 mm is a short lathe job; a production run of a special head is a cold-heading tool plus parts. The quote separates the two.
Send the stack, the hole and the alloy
Rivet type, diameter, total sheet thickness or exact length, hole size, head, material, quantity. A photo of the joint edge with a rule works. From 1 piece, quote within 12 hours.
