Replacement Nut for Cable Cutter 63041

A replacement nut for Klein's Standard Cable Cutter, Cat. No. 63041. On that tool the head hinges on a rugged bolt with a pin-set nut to maintain proper blade tension, which makes this small part the adjustment — not just a fastener holding two halves together.

Why the nut is the tension setting

Everything the 63041 does well comes from the jaws tracking past each other at the right pressure. The hook jaw grabs and holds the cable, the shear action makes the cut, and heavy-duty pins in the head serve as blade-stops. Set the nut too loose and the blades gap under 500 MCM copper; set it too tight and the handles bind and the crew starts levering on fibreglass that was never meant to take it. The nut is where that balance lives, and it is the part that backs off first once the cotter pin has been reused a few too many times.

Best for: service shops and utility crews resetting blade tension on a 63041 cable cutter that has started to gap under load.

Common questions

Is this the same as a hardware-store nut?
It is Klein's own replacement part, matched to the centre bolt and head of the 63041. A generic nut of the same thread will spin on, but it is not what the cutter's blade tension was set up around.

How tight should the pivot nut be?
Klein describes the joint as a pin-set nut that maintains proper blade tension. Tighten until the jaws track past each other with no side play, then back off to the nearest cotter-pin slot and lock it there.

Which other 63041 parts can I buy separately?
Klein lists the replacement cutter head 63081, centre bolt 63082, this nut 63083, washer 63084 and cotter pin 63085, so the entire pivot can be rebuilt without buying a new cutter.

Will a new nut fix a cutter that leaves ragged ends?
Only if the cause is a loose pivot. Worn or nicked blades need the replacement head, Cat. No. 63081. Check whether the jaws are still sharp before you blame the hardware.
