The BestGrip 3000B power stud 

The BestGrip 3000B tungsten head stud. A more aggressive prominent tipped stud. It will cope with extreme terrains where more traction is essential. Whether your boots are biting into weed or gripping barnacle clusters your confidence is increased knowing the studs are doing their job locked into your boot sole. Recommended to fit between deep profiled sole patterns or into deeper recessed wader screw slots. The 3.5 mm tip will make contact with the ground beneath your sole but not detract from the grip pattern on your boot. Requires BestGrip adapter to fit.

BestGrip power stud adapter and fitting tools are available.  

BestGrip power studs, designed in Italy in 2004 have rapidly become the go-to wader screw for anglers in fresh and saltwater.
