A closed-end wheel nut with a 60° conical seat, standard 17mm hex, and 34mm overall height. The closed dome design protects the wheel stud from road contaminants, while the 34mm body provides solid thread engagement for secure wheel clamping. Available in black or silver finish. Source
A 17mm hex is the most common wheel nut size across European passenger vehicles and is compatible with most OEM wheel braces and standard socket sets.
The 34mm height sits between short compact nuts and extended long nuts, making it a versatile choice across a wide range of wheel profiles and stud configurations.
A 60° conical seat creates clamping force through a matching tapered contact between the nut and the wheel's bolt hole. This angled engagement centres the wheel during tightening and forms a mechanical lock that resists loosening under dynamic loads. The seat angle must match the wheel; fitting a conical nut to a ball-seat or flat-seat wheel prevents proper contact distribution and compromises wheel retention.
Common Applications
Suitable for alloy wheels specifying a 60° taper seat with 17mm hex across a range of passenger vehicles:
European passenger vehicles (selected models using 17mm hex as OEM specification)
Aftermarket alloy wheels with standard 60° taper bolt holes
Classic and older vehicles using 7/16 UNF or 1/2 UNF thread
Replacement fitments on vehicles with M12 or M14 studs and conical-seat wheels
*Confirm seat type before ordering to avoid incorrect fitment.
