Screw-In Inserts for Wood
Reliable fastening points in wood with Rampa inserts
Why choose Rampa inserts for wood?
What is a Rampa insert?
A Rampa insert is a metal screw-in threaded bushing with a metric internal thread and a special external wood thread. It creates strong and reusable fastening points in wood without damaging the fibers.
How does a Rampa insert work?
The outer thread is similar to a wood screw and is screwed into a pre-drilled hole in the wood. The internal thread allows a bolt or machine screw to be fastened securely, ensuring a durable and reusable connection.

Installation guide for Rampa inserts in wood
Step 1: Preparing the hole
Drill a hole at the correct diameter and add a small chamfer to help the insert start smoothly.
Step 2: Selecting the right insert
Choose the insert type suited to your project — SK, SKD, BAV, and others. Our catalogue covers a wide range of sizes and load requirements.
Step 3: Installation
Screw the Rampa insert into the hole using a mechanical tool, Allen key or installation bit (type 507). Tighten evenly without over-torquing.
Step 4: Fastening
Insert and tighten your bolt or screw. The internal thread remains intact even after multiple assemblies — ideal for repeat use.
Which drill size to use?
The hole diameter must match the insert specifications exactly. Refer to our technical datasheets or PDF drawings for precise recommendations.

Frequently asked questions about Screw-in inserts for wood
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.
