Who is Kerb-Konus and what does it make?

Kerb-Konus manufactures in Amberg, Germany, threaded fastening elements: threaded inserts for metal, plastics and wood, threaded bushes for thin-walled parts, piercing rivets for sheet metal and thread-locking and sealing coatings. The company was founded in 1946, has had its own production in Amberg since 1970 and a second plant in Hadamar since 1982, and its management systems are certified to ISO 9001, ISO 14001 and ISO 50001. For a quotation, send us the name of the insert (for example Ensat, Mubux or Clifa), the thread, the length and the material of the host part.

Ensat inserts are self-tapping and are screwed into cast or drilled holes, with very high pull-out resistance: with a cutting slot, M2–M30 and inch threads, with three cutting holes, M3–M24, for plastic and wood, M2.5–M16, and the Ensat-3F variant, which forms the thread, M3–M6. For plastics there are also B-Lok expansion inserts, M2–M8, with a screw-locking effect, Mubux-A press-in inserts with helical knurling and S-Lok inserts, cylindrical or chamfered, embedded by heat or by ultrasound. Mubux-M and MO, M3–M12, are coated on the outside with an adhesive that locks them against rotation and seals.

For sheet metal and thin-walled parts there are Anchor rivet bushes (M2–M16, mini M2–M8 and the Anchor tank type variant, M3–M12), Clifa press-in nuts (M2–M10), Clifa AM spacers, for thin-walled parts, and AL, for fibre-reinforced composites, and Clifa SP threaded studs, pressed in with the head flush with the sheet. The Tuk-Rivet piercing rivet, Ø4 or Ø5, self-piercing, in stainless steel, free-cutting steel or hardened aluminium, makes joints with high load capacity, and Kerb-Konus also supplies the processing tools. The inserts are made from 11SMnPb30 and 35S20 steel, X6CrMoS17 and X8CrNiS18-9 stainless steel, aluminium alloy and brass. As a service, Kerb-Konus applies nylon patches for locking, sealing coatings and coatings that protect the thread from cataphoretic paint and weld spatter onto screws.

Frequently asked questions about Kerb-Konus

What does Kerb-Konus make?

Kerb-Konus makes, in Amberg, threaded inserts for metal, plastic and wood (Ensat, B-Lok, Mubux, S-Lok), Anchor rivet bushes and Clifa press-in nuts for sheet metal and thin-walled parts, the Tuk-Rivet piercing rivet with its installation tools, and thread-locking and sealing coatings applied to screws.

How do I choose a Kerb-Konus insert for an aluminium part?

For metal parts, including aluminium, self-tapping Ensat inserts are usually chosen, with a slot or three cutting holes, fitted in a cast or drilled hole. What matters is the internal thread, the length, the pull-out load and whether the part is dismantled often. Send us this data, plus the alloy and the wall thickness.

How quickly do you supply Kerb-Konus inserts in Romania?

We bring the inserts in on order, through EU supply channels, usually in 1–4 weeks. The lead time is 24–72 h when the item is available locally or at the supplier, for a standard code. For special designs, large quantities or Tuk-Rivet installation tools, depending on the brand and the specifications, the lead time may be longer.

Can you supply the same insert as in our part drawing?

Yes, if the drawing shows the Kerb-Konus name and code. If it shows only the thread and dimensions, send us the drawing with the mounting hole, the part material and the loads, and we check which Ensat, Mubux, S-Lok or Anchor insert matches the dimensions and the material.

What do I need to send for a quotation on Tuk-Rivet rivets?

The rivet diameter (Ø4 or Ø5), the material wanted (stainless steel, free-cutting steel or aluminium), the materials and thicknesses of the sheets to be joined, the force required in the joint, the quantity and whether you need the processing tool. We fill in the technical enquiry sheet for Tuk-Rivet together with you.

How do I request a Kerb-Konus quotation?

Send the Kerb-Konus code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
