Ferrari-Specific 70mm Wheel Bolts for H&R Spacer Installations and OEM Replacement
The H&R HRS1457011 wheel bolts are Ferrari-specific fasteners machined to M14x1.5 thread specification with a 70mm overall length and a Ferrari-pattern ball seat head with a 22mm hex. Sold in a set of 10, these bolts are designed for use as OEM replacement fasteners or as required extended-length hardware when installing H&R Trak+ wheel spacers on Ferrari vehicles. The extended 70mm length provides the thread engagement needed when a spacer is installed between the hub and wheel, ensuring full and safe bolt engagement at all times. H&R manufactures these bolts from high-grade steel to the same engineering standards as their wheel spacer and suspension products.

Frequently Asked Questions
What is the HRS1457011 used for?
The HRS1457011 is used as a replacement wheel bolt or as an extended-length bolt required when installing wheel spacers on Ferrari vehicles. The 70mm length provides additional thread engagement needed when a spacer adds distance between the hub and wheel center.
What is the thread specification of the HRS1457011?
The HRS1457011 uses M14x1.5 right-hand thread, which is the standard Ferrari wheel bolt thread specification.
What head type does the HRS1457011 use?
The HRS1457011 uses a Ferrari-specific ball seat head. It is critical to match the ball seat head type to the wheel's seat geometry. Using an incorrect seat type (such as a tapered or flat seat) will result in improper clamping and unsafe wheel installation.
How many bolts are included in the HRS1457011 set?
Each HRS1457011 order includes a set of 10 wheel bolts, which is sufficient for two wheels on a 5-lug Ferrari with a few spares.
Do I need to use the HRS1457011 with H&R spacers?
Yes, when installing H&R wheel spacers on Ferrari vehicles, extended-length wheel bolts like the HRS1457011 are typically required to maintain adequate thread engagement through the added spacer thickness. Always verify that you have the correct length for your spacer combination.
Is the 22mm hex on the HRS1457011 compatible with standard socket sets?
Yes. A 22mm hex socket, which is a standard size available in metric socket sets, is required for installation and removal of the HRS1457011.
Are H&R wheel bolts safe for track use?
H&R wheel bolts are manufactured to high-grade steel standards and are widely used on track-day and competition vehicles. Always torque to the manufacturer's specification and inspect bolts periodically for wear or damage.
What torque specification should I use for the HRS1457011?
Follow the torque specification for your specific Ferrari model as published in the factory service manual. Typical Ferrari wheel bolt torque is in the range of 90-100 Nm (66-74 ft-lbs), but always verify against your model's specification.
Installation Instructions
- Confirm the HRS1457011 thread size (M14x1.5) and seat type (Ferrari ball seat) match your wheel and hub requirements before installation.
- Clean the hub threads and wheel bolt holes of any dirt, corrosion, or debris.
- Thread the bolts in by hand to confirm smooth engagement before applying torque.
- Install the wheel and torque the HRS1457011 bolts to your Ferrari model's factory specification using a calibrated torque wrench.
- Tighten in a star pattern to ensure even clamping force across the wheel flange.
- Recheck torque after the first 50 miles of driving following any wheel removal and reinstallation.
