After heat treatment and hard carbon steel set screw, the grade reaches 10.9, plus black oxidation, so that the performance of this product and the color of the table are excellent.When using, the first bolt screwing in stay fixed parts of internal thread hole, and then pressed the end of the screw in the other parts on the surface of (or on the surface of the corresponding pits), even if the relative position of the two parts.
Set screws appear with a variety of tip (point) types. The different shaped tips have different properties that engineers can utilize. If an engineer were to use a detent to ensure proper nesting of the screw, they might choose to use a cone point type of screw. One might often need to use a flat point when the screw must press perfectly flat against a surface. The most common type is the cup point. This type works well because the surface is rounded so that a small surface area is in contact, but it does not have extremely high stress at one point like that of a cone point. Durability studies show that the cup point offers superior resistance to wear while maintaining a strong grip. Knurled cup points offer the added advantage of a locking action (similar to that of a serrated lock washer) that prevents the screws from working loose in high-vibration applications.
