Bolt FAQ & New Year Bolt special fed up of rusty/stuck bolts?

There seems to be much dissatisfaction with Mercedes oem bolts and locking bolts, so we’ve decided to offer our RAD bolts as a New Year Special!

There seem to be various problems with Mercedes bolts: corrosion issues, sticking bolts, shearing heads.

We specialise in selling only genuine oem wheels, but when it comes to bolts, oem are not good enough, so we buy from a company called RAD in Germany.

RAD bolt/locking bolt specification:
Manufactured to DIN EN ISO 898
Strength Class 10.9
Dacromet 500A coating – 240 hour salt spray test resistance guaranteed
Wheelgun proof - even the locking bolts can withstand 400Nm
Every single bolt is tested and logged on a PACE test machine

Mercedes bolts are zinc plated and last around 20 hours in the ‘salt spray test’, a laboratory test where metal components are sprayed with a corrosive agent and inspected for corrosion at various time intervals. The 20 hours that Mercedes bolts last is roughly equivalent to a year’s use.
The RAD bolts are guaranteed to 240-500 hours, so at least 12 years equivalent.

There are broadly 4 sizes of Mercedes wheelbolt, below are the sizes, art numbers and prices from Mercedes:

1. M12x1.5x21R12
