Explaining the benefits of "Left Thread HT LH," which is used in various ways besides preventing loosening, through a manga.
This booklet clearly explains the advantages of the hand tap series for left screws, 'HT LH', using manga. Fans use "left screws," and when counterclockwise force is applied to the cap, there is a risk that the blades may fall off if right screws are used, as they would loosen in that direction. Therefore, left screws are employed. Additionally, our left screw taps are available not only in standard types "HT LH," "SP LH," and "PO LH," but also through custom manufacturing. 【Features】 ■ There are three standard types in the left screw tap series: Hand tap for left screws "HT LH" Spiral tap for left screws "SP LH" Point tap for left screws "PO LH" ■ Left screws tighten counterclockwise ■ When the motor shaft rotates clockwise, counterclockwise force is applied to the cap ■ When counterclockwise force is applied to the cap, there is a risk that the blades may fall off if right screws are used, which is why left screws are utilized. *For more details, please refer to the link below or feel free to contact us.
