  • CORE4 SPECIFIC FEATURE: "J form" aerospace threads that are roll formed POST HEAT TREATING (after the steel alloy is brought to its final strength). 

    This is a unique process typically reserved for critical aerospace and engine applications that is proven to greatly extend the fatigue life of the fastener.

    Standard MSI studs DO NOT have this critical enhancement. 

  • M12 x 1.5 thread size
  • 75mm length: good for up to 12mm wheel spacers (dependent on wheel design)
    • "D-head" version provides enough clearance to allow servicing on the rear of E36M3/E46/E46M3 cars with wheel hub still on car (parking brake assembly off).
  • 90mm length: good for up to 20+mm wheel spacers
  • Beyond grade 12.9 material specifications 
  • Fatigue resistant geometry proven in endurance racing circles around the country
  • Fast start bullet nose
  • High performance Aerospace Specification Molybdemun DiSulfide based dry lubricant coating
