KB Self-locking press-fit threaded bushes

KB Self-locking press-fit threaded bushes ( insert to create threaded seats on marble, granite and ceramic slabs)

KB Self-Locking bush is a threaded bushing system that can lock itself, also called a pressure insert. It is used to attach sinks to natural stone or ceramic/quartz tops, to attach stone or other material slabs to ventilated walls, and for assembling furniture and interior design elements. This system is particularly useful for thin slabs such as marble, granite, ceramics, laminates, and quartz slabs and tiles.
Unlike other methods, this mechanically retaining bushing does not stress or create tension in the material to which it is applied.

The bushing is inserted into a cylindrical hole that is drilled using a standard drill. It does not require adhesives and is made of a stainless steel threaded sleeve (austenitic series 300 type) with a series of teeth crowns. This design allows the bushing to optimize space and not create protrusions behind the slabs

The main applications of the KB Self-Locking bushing are:

• production of kitchen tops, which speeds up work by quickly and cleanly securing sink fixtures without the use of chemical adhesives;
• production of furniture and interior design elements;
• installation of ventilated walls where bushings allow for superior fixing compared to the use of glue or resin.

How to use these KB Self-locking press-fit threaded bushes?

1. Drill with a 12-diameter diamond core bit tool a hole deep enough to let the insert enter
2. Check that the hole is clean and no larger than 12mm
3. Insert the bush pressing it with a rubber mallet
