Wovar Keilbouten

Do you want to mount a thick beam on the wall? Or do you want to anchor another heavy object to a stone wall or concrete? With the expansion bolts from Wovar you ensure an extremely strong anchoring of beams and hardware to stone or concrete. Roughly speaking, Wovar has two types of expansion bolts, namely with push-through mounting and with push-through mounting. The advantage of these expansion bolts with through mounting is that you can mount them by means of through mounting.

You do not have to fix this expansion bolt in the wall first and then apply the material to be anchored, but you can attach the expansion bolt directly through the material to be anchored. You must of course pre-drill this first.

Fitting expansion bolts is fairly easy. You drill the hole in the wall and the material to be anchored. Then use a hammer to secure the expansion bolt into the wall and firmly clamp the material to be anchored with the aid of a nut. Wovar sells Expansion bolts M6, M8, M10 and M12 thick. The lengths vary from 60 to 250 mm long.


In addition to expansion bolts for push-through installation, we also supply expansion bolts for pre-drilling mounting. This refers more to the traditional expansion bolt. You must first anchor this variant of expansion bolts in the wall. So that you can then mount the material to be anchored over the expansion bolt.

Which drill to use for these expansion bolts?

Expansion bolts are usually only used for anchoring in concrete or solid stone. You can use our concrete drill bits or hammer drill bits SDS-plus for this. You determine the thickness of the drill based on the thickness of the expansion bolt you want to use. Are you using an M6 expansion bolt? Then choose a 6.0 mm hammer drill for a expansion bolt M6. Do you opt for expansion bolts M8? Then you use an 8.0 mm thick drill. This is also how it works with M10 expansion bolts and M12 expansion bolts. The thickness of the drill is equal to the thickness of the expansion bolt.

The length of the drill depends, you guessed it, on the length of the expansion bolt and the material to be anchored. You should always make the drill hole 5 mm deeper than the length of the expansion bolt - the thickness of the material to be anchored. This ensures that there is always enough space to attach the expansion bolt.
