Hello, dear friend. At one time I had to work with a carpenter on a construction site for a week. In the process of work I learned from him some facts about lubricants. Used when driving screws and self-tapping screws. He told me, and I will share with you.
Clarification
Any screwed-in hardware fits well into the screwed-in object if it is lubricated. It is a fact. No one will argue with this. But sometimes there are disputes about how to lubricate. And there are even deep misconceptions that:
- Do not lubricate with soap! This is not true, soap can be lubricated, it does not have a negative effect on self-tapping screws and wood. Even if the self-tapping screw corrodes once, from a small percentage of alkali in the soap, then the self-tapping screw will not decompose further. It will even be good that the surface is covered with shallow shells. This will make it harder to unscrew. Analogy with rusty nails.
Do not lubricate with oil! Some people think that wood becomes loose when soaked in oil. But even if this is the case, how much volume should be pumped into the hole? When screwing in, only a thin film is involved, which in no way can spoil the structure of the tree.
How to lubricate self-tapping screws?
As you already understood from the above, you can apply for lubrication:
- Soap, liquid soap, as well as any detergent.
- Machine oil. Preferably clean. Not used.
- Graphite grease. It has good sliding properties.
- Margarine, sunflower or butter. Only as a last resort. it is not suitable to translate food.
- Litol and other similar lubricants.
- Epoxy glue, or moment, is sometimes used in unusual places, requiring additional strength.
Where is the lubricant required?
It is advisable to use the lubricant in the manufacture of wooden floors. Since there is a possibility of loosening of the connections. Which in turn causes creaks. The oiled self-tapping screw will no longer participate in the musical cacophony.
Can I do without lubricating the screws?
Yes, of course, for this it is necessary to pre-drill a hole in the intended place with a drill of a smaller diameter than the self-tapping screw. And screw your hardware into it. This is better than lubrication. But it is more labor intensive.
