Core4 “FLug” Floating Collar Lug Nut – M12 x 1.5

Core4 "FLug" Nut (Floating Collar "Wobble" Lug Nut)
Made in USA
 
Size: M12x1.5   17mm Hex (nice small socket size)
Fits: All Miata, MR2, Corvette; C4, C5, C6, and C7.  as well as anything else with M12x1.5 stud thread 
 
The strongest and most consistent lug nut on the market! FLugs prioritize the single most important thing a lug nut should do: CREATE STUD TENSION (also known as stud preload, or clamping force). 

Manufactured in the USA from hardened USA alloy steel, the unique floating collar design removes aluminum (wheel nut seat) from the under head friction equation when turning/tightening the lug nut (aluminum galls very easily).

By eliminating the detrimental effect of aluminum galling on stud preload (see chart in pic gallery), the Core4 FLugs can generate optimal stud tension/preload from the 1st time you tighten them when new, to the 30th+ time, without lubrication anywhere on the threads or nut seat. No other lug nut achieves this, regardless of coating type. Long term tension consistency = long term safety and long stud life.

The Core4 FLug design also reduces static bending strain on the studs from manufacturing tolerance stack up in the wheel hub and tapered nut seats of the wheel. If the tapered seats of the wheel aren't perfectly concentric and aligned with the wheel hub stud/bolt circle, 1 or more wheel studs are always subjected to static bending strain once tightened. This is a significant reason why there aren't tapered seat wheels on larger bolt circle and higher count bolt/stud heavy vehicle applications.

The M12x1.5 thread pitch is a highly common metric specification used primarily by Asian and some American automakers for their wheel studs, including most:
Toyota & Lexus: Nearly all models (e.g., Camry, Corolla, RAV4, 4Runner).
Honda & Acura: Almost all passenger cars and SUVs.
Hyundai & Kia: Most of their modern lineups.
Mazda & Mitsubishi: Traditional standard for these brands.
Ford: Select models like the Fusion, Focus, and Escape.
