These Wovar expansion bolts for push-through installation are ideal for anchoring heavy material in concrete. Consider, for example, attaching a beam to a full concrete wall. Expansion bolts with push-through mounting, also called push-through anchors or click bolts, have the advantage that they can be fixed on the basis of push-through mounting. This means that, after predrilling, you drive the expansion bolt straight through the material to be attached into the concrete, so that you have immediately secured the material to be anchored.
These through anchors are available in widths M6, M8, M10 and M12. The range includes both short and long expansion bolts, the lengths vary between 60 to 250 mm.
Please note: these expansion bolts can only be used in (full) concrete, when mounting in other surfaces, use our expansion bolts with pre-mounted installation.
The use of these expansion bolts is very easy. Pre-drill the material to be attached and the concrete substrate with a concrete or hammer drill. Make sure that the diameter of the drill is equal to the thickness of the expansion bolts. This means that an M6 expansion bolt must be pre-drilled with a 6 mm thick drill. The depth of the borehole differs per expansion bolt, of course, and is specifically named for each expansion bolt.
How do I attach an expansion bolt?
Proceed to drive the expansion bolt through the material into the concrete base and tap it well using a simple sledgehammer. Then tighten the supplied nut with washer properly.
By driving in the expansion bolt and tightening the nut, the protruding cone is pulled into the bolt. This causes the bolt to expand and clamp itself into the concrete. This way you are assured of a rock-solid fixation.
