Whichever way I screwed these shafts into my dart barrels I could feel a ridge, they would not sit flush: the shaft threads were all OFF-CENTRE!
All other shafts I use are fine so these must have a manufacturing defect.
I'm not blaming the seller but Harrows need to check their tooling, these shafts are not cheap
£10 worth of new shafts straight in the bin!.
Not happy, will not buy these again.
