Fitting Advice
Match the nut diameter and thread pitch to the bolt or stud. Start the nut by hand to avoid cross-threading, then tighten with the correct size spanner or socket. Take care when fitting to avoid marking the black finish.
These are plain full nuts without a self-locking feature. Where the assembly requires resistance to loosening, select a suitable locking method for the application.
