The Abbey Bike Tools Spin Nut for Micro Bearing Press will act as a spare in the event that your spin nut disappears during use or falls behind your home workbench.
The spin nut is designed to work with Abbey's light, compact Spin Nut Micro Bearing Press, primed to handle all small bearing jobs, where the delicate bearings have an inside diameter of 13mm or less. It will thread easily onto the press shaft to keep the desired drift firmly in place as you work.
