FAQs

What is the seat type for these bolts?

These bolts feature a 60-degree conical (tapered) seat.

Can I use these with factory wheels?

Only if your factory wheels require a 60-degree conical seat and the 50 mm length does not cause internal interference.

Do I need to grease the threads?

Generally, bolts should be installed clean and dry unless the manufacturer specifies otherwise, as lubricant can affect torque readings.

What tool size do I need?

You will need a standard 17 mm hex socket.

Are these bolts sold individually?

Yes, H&R bolts are typically available individually to allow you to purchase the exact quantity needed.

What does the 10.9 grade mean?

10.9 refers to the property class of the steel, indicating a high-tensile strength suitable for critical automotive fasteners.

Troubleshooting

Bolt feels difficult to thread

Remove the bolt immediately and check for cross-threading or debris in the hub; clean threads if necessary.

Bolt contacts internal hub components

The 50 mm shaft is likely too long for your current setup; verify clearance requirements or use a shorter bolt.

Finish is scratching during installation

Use a nylon-sleeved wheel socket to protect the black finish from the metal-on-metal friction of the tool.

Pros and Cons

Pros

  • High-tensile 10.9 grade steel construction
  • Durable black finish prevents rust
  • Precise 60-degree conical seat ensures safety
  • Industry-standard dimensions for wide compatibility

Cons

  • Specific 50 mm length may be too long for factory wheel setups
  • Requires careful measurement to avoid hub obstruction
  • Black finish may show wear over time with frequent removals

Setup, Compatibility & Care

Before installation, ensure your vehicle hub uses an M12 x 1.5 thread pattern. To install, manually thread the bolts to ensure they are not cross-threaded before using a torque wrench. Do not use an impact gun for the final tightening, as this can damage the bolt finish or threads. Clean the bolt threads periodically with a wire brush to remove debris. If you observe any signs of thread deformation or significant coating loss, replace the bolts immediately. Always confirm that the total length of the bolt protrusion behind the wheel matches your vehicle's specific clearance requirements to avoid contact with the brake rotor or parking brake mechanisms.
