Threaded Inserts
Threaded Inserts are nuts with threads on both the inside and the outside. The screw thread on both sides makes it possible to make an attachment point in a different material, like wood. After screwing in the threaded inserts, it is possible to place a bolt or threaded end in it. The internal threads are metric and correspond in sizes to the standard metric threads of bolts. For example, an M8 ramp nut is suitable for an M8 bolt and an M10 screw-in nut for an M10 bolt. The ramp nuts have a handy notch for a screwdriver, so you can easily attach them.
Wovar supplies very strong and high-quality galvanized threaded inserts in sizes M4, M5, M6, M8 and M10. Screw-in nuts are usually available from stock and you can always count on fast delivery with Wovar.

These threaded inserts for wood, also called screw-in bolts, or rivnuts, are super handy hollow threaded inside and outside bolts that can be nicely incorporated into a construction. Their outer screw threads allow you to screw them into the material. These bolts are ideally suited when you are building furniture. These screw-in bolts can be completely screwed into the material, after which you can, for example, mount wheels under your cabinet or chair using M4,5,6,8 or 10 bolts.
Easily screw in Threaded Inserts
The Wovar threaded inserts come standard with a flat head, which you can use to tighten them. If you are not comfortable with this, you can screw a bolt with washer into the nut. In this way you can easily remove this ramp nut threaded insert with a torx or allen bit. Another option is to take a bolt and screw in a nut after a while. Make sure the bolt can rotate just far enough into the ramp nut. In this way, after screwing in, you can easily remove the bolt again with a wrench and the threaded insert is nicely screwed into the wall.
An alternative to the threaded insert is the T-Nut. T-Nut are attached by hitting them, on their flat T top surface into the material.
