We specialize in very small micro setscrews (mini set screws) from M1 to M2.5.
  Nominal diameters of our very small micro set screws (mini set screws) are M1, M1.2, M1.4, M1.6, M1.7, M2, M2.3, M2.5, and M3. Lengths are 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm, 5.0mm and 6.0mm. Pointed tip shapes of our very small micro set screws (mini set screws) are "flat point", "cone point" and "oval point / round point". Materials are steel or stainless steel.

 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).
 Therefore, the hand of the assembling worker does not get oil at the time of work. In addition, this setscrews is easy to use in automated assembly, and it is hard to rust.
