Overflow screw M10x1.25 The overflow screw - (eye screw) is made of the highest quality free-cutting steel. The screw is intended for eyelet terminals. The screws are hollow in the center and have holes in the sides to allow oil or other liquid to flow through. Screws are divided according to thread and length. The shorter screws have two holes, while the longer screws have four holes. The screw is matched to the hole in the eyelet (the same division into metric and inch). To secure the connection and seal it well, we can use a metal-rubber washer or a copper washer under the eye bolt.Technical data: Manufacturer: Teper Material: Automatic Steel Thread Type: Metric Thread Size: M10x1.25 Screw length: 18mm Number of eyes: 2
