TID-Inox which offers all sizes and features of stainless steel bolts and washers also announces the availability of new inserts. These 316 L stainless steel parts (the reference for the navy) are screwed directly into the polyester.
A waterproof and resistant insert
To install an insert, simply drill the bridge according to the manufacturer's recommendation (one diameter smaller than the size of the insert). The insert is then screwed directly into the polyester. Its very deep and sharp thread offers a very high resistance to tearing.
The insert does not have an opening in the bottom, so it remains completely sealed if care is taken to mount it with Sika sealant or resin before screwing it in. The fitting is then screwed with a stainless steel screw directly into the insert. The assembly and dismantling of the fittings is then made easier.
The inserts are 25 mm deep. Therefore, there must be enough space below deck to install it. They are available in 4 sizes to screw 6, 8, 10 or 12 mm screws.
For ceilings
In the case one does not want to cross the bridge, there are inserts that are integrated into the thickness of the material. They will be useful to fix a lamp in a ceiling for example so that the screw does not appear on the deck. These inserts, which have less pullout resistance than the model shown above. These inserts have a kind of reverse gearing that holds them in place in their hole. They are available in 3 increasingly resistant sizes for holes up to 7.5 mm deep.
These inserts can even be used on Plexiglas portholes or under a polyester deckhouse. Once the hole is drilled, the insert is simply installed with a few hammer blows.
Also on aluminium
If the material is too hard (carbon, aluminium...) to fit an insert, there is the solution of inserts with self-tapping bushings. These models are not watertight (they are uncorked at the bottom) but can be used to replace threads that have become loose. For example, it can be used on a mast. However, please note the compatibility between the stainless steel insert and the aluminium mast. To avoid the risk of corrosion, metals should be insulated with Tef-Gel insulating paste.
