Extra Reach for Spacers Without Sacrificing Clamp Load
The H&R 1455502 wheel bolt is a German-made M14x1.5 ball seat bolt built to Grade 10.9 strength, offering 55mm of thread length for Mercedes-Benz applications running slightly thicker wheel spacers or wheels with a deeper bolt pocket. The 17mm head and factory-style ball seat keep installation straightforward with standard shop tools.

FAQ
What is the 1455502?The 1455502 is an H&R M14x1.5 wheel bolt with a Mercedes-Benz ball seat, 55mm thread length, and 17mm head, sold individually for factory-style or spacer-compatible wheel installations.
How do I know if I need the 50mm or 55mm bolt?Bolt length should equal the factory length plus the thickness of any spacer used, while staying within H&R's minimum and maximum thread engagement guidelines. If your spacer requires a bit more reach than the 50mm version allows, the 55mm bolt is the next length up.
Can I use this bolt with wheel spacers?Yes. The 55mm length is commonly chosen when adding a moderate-thickness spacer, but always confirm exact bolt length against the spacer manufacturer's specification.
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.
Is a too-long bolt dangerous?Yes. A bolt that is too long can bottom out in the stud hole before fully clamping the wheel, or interfere with brake components, so always verify screw-in depth after installation by turning the wheel by hand before lowering the vehicle.
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.
- Spin the wheel by hand while the vehicle is still raised to confirm the bolts are not bottoming out or binding.
- After driving a short distance, recheck torque on all wheel bolts.
