Spotted these genuine Honda replacement mower blade bolts and price was for two, great value as others wanted double the cost. Used plenty of Cooper slip to reseat the blade and retaining washers, new bolts fitted a treat. Easy todo. Kept the better old bolt as a spare and put the rounded head one in recycling.
(Only got the rounded one out with heat torch and large grips)...
Delivered very speedily considering the Covid 19 lockdown kicked in 1day after ordering...
Many thanks to the supplier “Tippetts”.. 👍👍🌟
