Zusammenfassung: | PURPOSE:To manufacture a low magnetic insert simply at a low cost by working a female screw inside the insert along the axis from the other end of a bar section provided with a head projected in the direction of a radius in one end. CONSTITUTION:A female screw 20b for screwing a bolt from one end of a bar section 20c is formed by cutting or rolling in a state of not forming a screw section 21a of the low magnetic bolt 21 on the market. The low magnetic bolt mass produced with good quality and at a low cost is used, and instead of a male screw machining process in a manufacturing process of the bolt, an insert is manufactured by machining a female screw in the inside from the end of the bar section along the axis. According to the constitution, low magnetic steel is changed into magnetic steel. Forging and extruding processes are not required, and the insert 20 with good quality can be easily manufactured at a low cost. |
