คุณลักษณะ

• Half ball point processing is applied to the tip of the short hand side. The half-ball makes the approach to the hexagon hole easier than the conventional one.
• Half-ball processing provides ease of insertion and torque transmission equivalent to conventional products.
• You can turn the screw from a maximum angle of inclination of 32°.
• In order to ensure a homogeneous and highly accurate tempering (heat treatment) hardness (HRC60°±1°), we have adopted a fully oxidation-free and decarburization-corrected quenching method using a closed furnace instead of using a continuous furnace.
• The pipe handle can be used to tighten at the ball point.
• Partially painted so that you can tell the size at a glance by the color.
• Surface treatment with special chrome plating provides excellent abrasion resistance and does not rust over a long period of time.
