Description

The JIS 7388/2/B-1983 Pull Stud (Special Size) is a precision-engineered retention stud designed according to Japanese Industrial Standard (JIS 7388 Type B). This pull stud is used in SK series tool holders and ensures secure clamping between the CNC machine spindle and the tool holder.

As shown in the technical drawing, this pull stud is manufactured with exact dimensional accuracy, specific chamfer angles, and precise thread geometry to meet demanding CNC machining requirements. Pull studs are a critical safety component—any dimensional deviation or low material quality can lead to poor clamping force, vibration, tool pull-out, or machine damage.

This special size JIS 7388/2/B pull stud is made from high-strength special alloy steel and is properly heat-treated to achieve superior rigidity, wear resistance, and long service life. It is suitable for high-speed machining and heavy cutting conditions where reliability is essential.
