BONOSS forged shell-type BMW wheel bolts consist of ISO grade 12.9 bolts and AL7075-T6 shells.
The minimum tensile strength of ISO grade 12.9 BMW wheel bolts is 1,220 MPa which far exceeds the standard grade 10.9’s.
Since tensile strength is the amount of pull the bolt can withstand before breaking, changing to higher-grade wheel bolts improves safety.
These shells protect BMW wheel bolts from debris and water corrosion and maximally beautify your wheels.
Such BONOSS BMW wheel bolts certainly won’t disappoint you.
