Why upgrade your wheel bolts? Check out the pictures below (thread magnification) for an example of thread wear on a 348 bolt.

Hill Engineering insists on full material traceability for all of their bolts with records being held for a minimum period of 6 years. The design & development stage of these bolts involved destruction testing at a major UK Automotive Test House to make sure that our bolts conformed to original specification. Copies of the test result are available by request.
