Racing karts with magnesium wheel rims often have clearance issues that make it difficult to use standard flange-type lug nuts. Don't be tempted to use regular hex nuts! Not using a flanged nut can cause galling around the lug hole in the rim. This kit uses jetnuts with a full 14mm OD flange, but the reduced 10mm hex size allows easier socket access.
Complete CIK-approved kit includes 12 M8 all-metal self-locking jetnuts and 12 washers, enough for four 3-bolt wheels. A valve stem core wrench is also provided. Recommended by Douglas Wheels.
