Bull Nose Extended Wheel Studs for MX-5 & 124
Suits: Mazda MX-5 NA, NB, NC, ND, Abarth 124 (12.8mm or 14.7mm knurl)
20mm more thread for your wheel nuts when you run spacers. The bullnose tip locates the nut and helps stop cross-threading.
- 60mm long, up from the factory 40mm
- M12 x 1.5mm thread, grade 10.9
- 12.8mm or 14.7mm knurl to suit your hub
- Dacromet surface treatment for corrosion resistance
Why upgrade
Wheel spacers push the wheel out, which leaves less thread for the wheel nuts to grab. These studs are 60mm long, 20mm longer than the factory 40mm stud, so you get that thread back.
The bullnose tip locates the nut before the threads meet, so quick wheel changes are easier and cross-threading is much less likely. Grade 10.9 is the standard for wheel studs, and the Dacromet surface treatment adds corrosion resistance.
Which knurl do I need?
- MX-5 NA6, NC, ND and Abarth 124: 12.8mm knurl, front and rear
- MX-5 NA8 and NB: 12.8mm knurl front, 14.7mm knurl rear

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.
