Tri-Knobs – Male

Himould® plastic Tri-knobs are moulded in tough, durable polypropylene and have been an industry favourite for many years. The unique three- cornered knob allows an exceptional amount of torque to be applied to the threaded inserts whilst still being comfortable to hold and turn.
A wide variety of both male and female-threaded mild steel inserts can be provided, either ex stock or moulded as a special run. Where a water environment is present, special stainless steel insert options are also available. The maximum thread size is M10 or 3/8” BSW. There is also an unthreaded version which has a hexagonal hole only. All standard Tri-knobs are black in colour, however other colours can be quoted for specific requirements.
