Used for attaching a small ship's battery switch. The thickness of the instrument was as large as 50 mm, it was difficult to find SUS tapping of sufficient length, but it was lucky to meet this product.

It was saved without the length so far with other goods. Although it was thing that it was unnecessary to pilot holes, I used it after preliminarily punching holes with φ 4.0. From the sense of torque it may have been good even at φ3.5 or so, but it is impressive that it stopped because it has a length. The exterior is considerably dark gray than the picture. Is not it stainless steel color, but is this "stainless steel coating stronger than stainless steel screw"? I hope that you will do your best without problems until the life of the instrument.
