Brass Shim OVERSIZED Collapsible
The Golfmechanix "One size fits all" OVERSIZED Universal Brass Shims are specifically designed to bridge the "fit gap" across a wide range of tolerances between mismatched shaft tips and hosel bores.
The universal fit is made possible by impressing collapsible ribs along the "ears" of the shim. The ribs are designed to gradually flatten out as the shaft is driven firmly into the hosel.
Each shim weighs less than 1.6 grams which has virtually no effect on swing weight.
