CATALOG / PART FAMILYSPANNERS & PULL STUD
Spanners & Pull Stud CNC Machine Parts39 product records listed in this part family.
This family carries the small parts that make tool holding work: pull studs that retain a holder in the spindle, ER-MS special nuts, spanners for holder and collet work, and the thread gauges used to check the threads they screw into. Pull stud fitment is machine-specific, so quotation starts from the spindle standard and the holder taper together.
TYPICAL APPLICATIONS
- Retention of tool holders in the machine spindle
- ER-MS nut replacement on collet chucks
- Spanner and wrench work on holders and collets
- Thread checking with plug and ring gauges
WHAT TO SPECIFY
- Spindle standard and the pull-stud thread required
- Holder taper the stud will be fitted to
- Nut type and thread for ER-MS replacement
- Thread size and tolerance class for gauges (the metric range listed here runs M1 to M300)
How do I choose the right pull stud?
Match it to the spindle standard and the holder taper together — both decide the thread and the stud length. Send both and we confirm.
Are the ER-MS nuts a direct replacement?
They are listed for ER-MS type tool holders in the series shown on each record. Check that record against the holder you are running.
Are thread gauges available in other sizes?
The metric range listed in this family runs from M1 to M300, with tolerance classes stated per record.
