- Class 4g 6g metric thread
- Magnetic particle crack tested
- Tensile and shear requirements per JIS 6339
- All locations of the pullstud that make contact with ground spindle mechanism components are ground
- Base of pullstud flange is ground to assure perpendicular alignment between pullstud and taper of toolholder
- Ground pilot and tight pitch diameter tolerance help maintain accurate concentricity between threads and knob limiting the expansion or flaring of the small end of the taper
