 Generally, small diameter of the hexagon socket set screws, if it is tightened strongly in the hexagonal bar spanner, hexagonal hole is cracked.

 Our hexagon socket set screws is using the Nickel-Chrome-Molybdenum Steel (SNCM240) to the material. And furthermore, the precision of the hexagonal hole is good.
 In addition, the hardness by the heat treatment is high (HRC50 ~ 53), there is also toughness. Therefore, the hexagonal hole is not broken even if you tighten it until you can wrench off a hexagonal bar spanner.

 At that time, when you move the magnet to the hexagonal hole, because it does not have a hexagonal hole deformed, broken hexagonal bar spanner is attracted to the magnet, it will be drawn from the hexagonal hole.

broken test

 Our hexagon socket set screw dries surface rust prevention oil with a vacuum hot-air drier after black oxide finish (surface treatment).
