In which materials can I use Rampa inserts?

Primarily wood (solid, plywood, particle board, MDF), plastics (ABS, PA, POM, composites), and light metals when the insert with the right geometry is choosen accordingly.

Do you provide drawings or 3D files?

Yes. For most Rampa series (B, SKD, SK, SKL, SKD330, ES, ESK, ESD, BAV, BAN, BAS), 3D models are available on www.traceparts.com.

How strong is the connection (pull-out / shear)?

Highly dependent on the receiving material, drill diameter, embedment depth, and insert type. We have various values for Rampa nuts in wood that are specified in ETA 12/0481. We do have supplier data, but exact values can only be obtained through empirical testing, as they are highly material-dependent and application-specific.

Inner hexagon Rampa insert type SKD

LOADING ZOOM

Rampa wood screw-insert, type SKD with inner hexagon socket drive, sealing collar and unthreaded lead to facilitate mounting.

Description

The Rampa screw-insert type SKD can be mounted without special tooling in softer wood, plastics and even lead.
Thanks to the unthreaded lead, the insert will fall into position before screwing, what ensures mounting in the rigth angle (that follows the drilled hole).
Available in steel zinc plating, brass and stainless steel 303 from M4 up to M16!

Frequently asked questions about Inner hexagon Rampa insert type SKD

What should I take into account when using an internal hex screw-in insert?

Be aware that the inner hexagon, although very practical for installation, does reduce the effective length of the internal thread. With short types or inserts made of zamak, this may result in a less wear-resistant or less strong metal threaded connection.
