Fixaball BSF Lock Half Thin Hexagon Nut Self Colour plus Left Hand Thread

For BSF threaded fastenings, these Fixaball imperial lock nuts are supplied in Grade 1 steel with BZP and self colour options. The range covers half and thin locking nuts, with selected sizes available in left hand thread.

Used as a secondary nut behind a standard nut, this pattern helps resist loosening from vibration or torque. Half and thin nuts are approximately 2/3 the thickness of a full nut, making them suitable where a slimmer locking nut is required within a BSF assembly.
