HFS(R) 12'' & 17'' Guillotine Cutter Replacement Knob - Durable Paper Holder Adjust Knob, Easy Install, Precision Spare Part

This part is bad and the company is even worse! The knob part itself fits but the weighted bolt on the bottom is actually a little too small so once it’s put on and used a few times it becomes stripped and impossible to get off. The company is no help at all and asks for all kinds of info then just does nothing. Emailed their head person as they directed me to and they also just ignore you. Do t waste your money with this company they are a joke. Cheap china made not worth the money!

Fit my 17" hfs new tool kit on arm cutter perfectly after I stripped out the threads on my original one by over tightening it. In a pinch you can put washers on the stripped one to make it contact a different spot on the bolt. Now I barely tighten this knob down to make it last

This replacement knob assembly is easier to grip than the original part and the steel in the screw is black anodized which is typically a harder material than the original zinc plated steel part.
