Ref. Details Price
INS-030 for IOM/M/10R, M3 studding, captive part for fin, plus nut to retain ballast
6.00
This is the length of stainless steel studding, stainless steel insert and retaining nut that we use at the bottom of our fins when the ballast is to be removable. The stainless steel insert is bonded into a round keyhole in the fin and prevents the studding from pulling out. The retaining nut fits into a counterbored hole in the underside of the ballast. It is better that the counterbored hole has the brass seat, item INS-seat, fitted to resist wear.
