Imperial Half Lock Nuts - Mild Steel - Bright Zinc Plated

(JNL12 - 3/4" UNF Left Hand Thread)

McGill half nuts are manufactured to be within excellent tolerances. These are commonly used for motorsport when securing rod ends to link bars. As the nut is half the thickness, it allows for maximum adjustment.

  • Ideal for securing linkage bars in place on the rod end to prevent rotation of the bar.
  • As the nuts are half the thickness of standard nuts, a finer adjustment can be made as the rod end can be screwed further into the link bar.
  • Mild steel, CNC precision machined.
  • Protective coated for corrosion resistance (Bright Zinc Plated).
  • Great price & Free 1st Class UK P&P.
To complement these nuts, we have a range of other products available in our online store. We supply suitable all components in a range of imperial and metric sizes.
