Product B is a 10-set kit of M8 double-ended bar mounting screws and nuts for chainsaws. Buy the one that matches your head; neither is a substitute for the other.

Questions and answers
- Will the Pole Saw Blade Retaining Bolt fit my chainsaw?
- No. It is a 5/16" carriage bolt set for Fanno, Marvin and Smith 20H pole saw heads, not a chainsaw bar mount.
- Are the Healifty screws the same size as the pole saw bolt?
- Close but not the same. The Healifty screw is M8, about 5/16", but it is a double-ended chainsaw bar screw, not a carriage bolt with a wing nut.
- Which lasts longer?
- Both are plated or plain steel hardware that wears with use. The pole saw bolt's wing nut is easy to replace; the Healifty iron screws are softer than hardened bar studs.
- Do I need ten sets?
- Only if you service several chainsaws or lose bar nuts often. For one pole saw head, the three-set Pole Saw Blade Retaining Bolt pack is enough.
- Can I use the Healifty kit on a pole saw?
- Not reliably. The thread may match, but the head and nut style differ, and the kit is sold for chainsaw bar mounting.
