Wheel nut suitable for 7/16"UNF wheel studs intended for attaching aluminium wheels with a flat face (not conical) where the nut attaches, requiring a sleeve nut with a 5/8" (16mm) plain section 3/4" long where the nut goes into the wheel.

These wheel nuts have a flat face under the hexagon and use a flat washer in contact with a flat face of the road wheel.  This wheel nut RTR1346 is intended to fit wheels with a hole where the studs protrude 5/8" (16mm) diameter, the plain section of the nut is 5/8" (16mm) to fit this type of wheel with a close fit. 

Some wheels have 11/16" (17.5mm) holes where the studs protrude, these require a nut with a suitably larger plain diameter below the hexagon. Wheel nuts for this application are no longer available however a solution is at hand. We offer a 'top hat' shaped adaptor sleeve RTR1346SLEEVE with an internal diameter to suit the nut and an outside diameter of 11/16" (17.5mm) which slips over the plain diameter of this nut RTR1346 and converts the nut to one suitable for wheels requiring a 11/16" (17.5mm) sleeve nut. As the 'rim' of the 'top hat' sleeve replaces the washer, the washer supplied with the nut can be discarded.
