Glass Beads 150 micron Epoxy Filler
GolfMechanix Shaft Beads are tiny spherical glass oxide granules, roughly 150 microns in diameter (0.005″). They are selected specifically for their gap filling ability in shaft-to-hosel bore fits built under current industry standards.
Adding glass beads to the epoxy mix reduces viscosity and provides a consistent cushion between the shaft and hosel wall which eliminates the possibility of shafting the clubhead off-center.
