Muteki SR48 Open End Lug Nuts – Blue 12x1.25 48mm (Set of 20 + Key Adapter)
The Muteki SR48 32905U Open End Lug Nuts are ultra-lightweight performance lug nuts from Japan, designed for maximum strength and style on wheels with extended studs or aftermarket applications. Crafted from high-strength chrome vanadium steel (28DCRVM spec), each nut weighs just 2 oz with thin-wall construction for reduced unsprung weight. The oversized taper seat ensures perfect contact and centering, while the external 17mm hex drive and knurled tips provide easy installation and secure grip.
