The GMP Tools Seloc Pin, M6 x 24 mm (part 32307, Millennium part 536072) is a fastening pin used two per assembly on GMP cable blower accessories, securing moving parts during jetting operations. It's a routine spare parts item crews keep stocked for field repairs when a pin shears or works loose from vibration. Ordering to the required quantity of two keeps a full repair on hand in one part number. Stock it with matching thumb nuts, thumb nut caps and drive belt assemblies for the same GMP equipment.
