12.7-12.8mm


These studs are ideally for use with older U.S. domestic vehicle hubs that require 1/2" knurl, usually with 7/16" thread, where converting to metric thread is desirable.

Alternately, they can be used as conversion studs for many hubs that normally use M12 wheel bolts, common on German vehicles.

Ensure that studs are pressed, or hammered in from the rear, with sufficient force to seat completely.

Features:

  • Material: 40Cr heat treated
  • Thread: M12x1.25
  • Length: 60mm below the head
  • Knurl length: 9mm
  • Knurl diameter: .500-.503"

 

12.8-12.9mm

These studs are compatible with the majority of older Datsun and early-Nissan vehicles, the knurl matches the Nismo studs, but with a slightly smaller diameter. Made from high strength cromoly, zinc plated for corrosion resistance, and tempered to be safe for use with aluminum lugnuts.

These are also the ideal studs for use in 300ZX/Z32 Twin-turbo and Skyline GT-R rear hubs, where the hub material is stronger, and tolerance is less flexible. Other 300ZX and Skyline models should use the regular 13mm knurl studs.

Ensure that studs are pressed, or hammered in from the rear, with sufficient force to seat completely.

Features:

  • Material: 40Cr heat treated
  • Thread: M12x1.25
  • Length: 60mm below the head
  • Knurl length: 9mm
  • Knurl diameter: .504-.508"

These studs may also be used in many Toyota and Lexus applications, however the thread pitch will be different. Toyota studs generally use M12x1.5 thread pitch, which will therefore require different lug nuts if used.

Ensure that studs are pressed, or hammered in from the rear, with sufficient force to seat completely.
