RAD processes only top-grade steel from certified German steelworks. All wheel fasteners are hardened and tempered to strength class 10.9 or 10 according to DIN/ISO standard 898. They meet the statutory requirements of all countries - including the USA.

At RAD, every computer-controlled machine is manned by operators who constantly check the quality of the products so that only goods of top quality reach the customer.

All RAD bolts feature Dacromet coating, a specification required by Mercedes Benz, which results in a dull gray finish that lasts for years.

Quality control

All RAD products are subject to constant inspection and quality control throughout the entire production process. This ensures that the product always meets its specification exactly.

2-Piece Bolts

Now available exclusive to RAD are 2-piece bolts. These bolts feature a separate washer which is separate from the main bolt. These bolts retain torque much longer than conventional 1 piece bolts. Many manufacturers are now supplying 2 piece bolts from the factory like Audi/VW. Maintain proper wheel torque with extended bolts from RAD.
