HFM.Parts BullNose Extended Wheel Studs help to accommodate for the loss of thread you may have when you’re using wheel spacers. HFM.Parts Wheel Studs provide an extra 20 mm of thread from the standard 40mm wheel studs, and the Bull Nose end makes them easy to thread on during quick changes as they help to locate and prevent cross-threading.
HFM.Parts Extended Wheel Studs are manufactured to a hardness of grade 10.9. Surprisingly, increased hardness can make wheel studs more fragile, which is why grade 10.9 is viewed as the standard. This grade strikes an ideal balance between hardness and toughness, helping to avert breakage. Additionally, our wheel studs undergo a surface treatment that enhances rust and corrosion resistance while boosting overall strength.

Our Story
We weren't always HFM.Parts; we were Holford Motors. Our brand's identity was forged not in an office, but on the local circuits in the high-stress world of competitive drifting. Our ultimate testbed was our Nissan S14 Drift car, driven by champion Luke Fink. Pushing that car to its limits exposed a crucial truth: achieving genuine, repeatable performance meant relying on components that simply weren't available affordably on the market.
The HFM.Parts brand was born
We made the commitment to design and manufacture the uncompromising, high-quality performance parts that we, as competitive racers, demanded ourselves. Every component you see is a solution conceived, tested, and proven by us. When you choose HFM.Parts, you are investing in components engineered by racers, for racers, ensuring your vehicle delivers its maximum performance potential.
