This single heavy duty clamping nut secures ER collets with a forty millimeter (1 57 in) thread profile. Machinists rely on it to lock down tools for precise metal cutting operations across CNC lathes and milling centers.

✅ 40 mm (1 57 in) thread with 1 5 mm (0 06 in) pitch for solid grip
✅ 40Cr alloy steel heat treated to HRC48 50 for max strength
✅ 50 mm (1 97 in) outer diameter and 24 mm (0 94 in) thickness for stability
✅ Replace worn hardware on extension bars or tool holders

💡 What makes a handy replacement clamping nut for CNC lathe tool holders stay secure under pressure?
The real deal hinges on material hardness and consistent thread depth across every cut.
- High grade forged steel resists cross threading during repeated swaps
- Proper pitch alignment distributes clamping force evenly around the collet body
- Straightforward hand tightening prevents cam damage while locking bits snuggly
Just give it a quick wipe and check for burrs before sliding it back onto the drawbar. That simple routine keeps your setup dialed in without wasting shift time.
