The Small Part That Keeps Every Wheel Where It Belongs
The H&R 1455002 wheel bolt is a precision-machined M14x1.5 ball seat bolt built in Germany to Grade 10.9 strength standards. Designed for Mercedes-Benz ball seat wheels, this 50mm bolt is the correct choice when reinstalling factory wheels or running thinner H&R wheel spacers that still fall within the stock bolt length range. Keeping a few extras of MPN 1455002 on the shelf means a stripped thread or lost bolt never turns into a delayed install.

FAQ
What is the 1455002?The 1455002 is an H&R M14x1.5 wheel bolt with a Mercedes-Benz ball seat, 50mm thread length, and 17mm head, sold individually as a factory-style replacement or spacer-compatible bolt.
Do I need a special seat type for Mercedes wheels?Yes. Mercedes-Benz factory and many aftermarket wheels use a ball seat design rather than a conical or flat seat, so the bolt seat type must match the wheel exactly for proper centering and clamp load.
Can I use this bolt with wheel spacers?Yes, as long as the spacer thickness still allows adequate thread engagement. The new bolt must be longer than the factory bolt by the thickness of the spacer used, so always confirm total length against your specific spacer.
How many bolts should I order?Order a full set for the vehicle plus one or two spares. Most passenger vehicles use five bolts per wheel, so a typical set is 20 bolts with 2 extra for service needs.
What torque should these bolts be tightened to?Always torque to the vehicle manufacturer's specification, since torque values vary by chassis and wheel material. Overtightening a ball seat bolt can damage the seat and undertightening risks wheel separation.
Is a 17mm socket the correct size for installation?Yes. These bolts use a 17mm hex head, which is compatible with standard lug wrenches and most impact sockets used in automotive service.
Will these bolts fit non-Mercedes vehicles?Only if the vehicle uses the same M14x1.5 thread and ball seat design as Mercedes-Benz factory hardware. Always verify thread pitch and seat type before ordering for a non-Mercedes application.
What is the minimum thread engagement required?For M14x1.5 bolts, H&R recommends a minimum of roughly 7.5 turns, or about 11mm of load bearing thread, to maintain safe clamping force.
Install Instructions
- Confirm the wheel uses a Mercedes-Benz ball seat and the correct M14x1.5 thread before installing.
- Hand thread the bolt into the wheel stud to avoid cross-threading.
- Snug each bolt in a star pattern before final torque.
- Torque to the vehicle manufacturer's specification using a calibrated torque wrench.
- After driving a short distance, recheck torque on all wheel bolts.
