Plastic Knob in kit form.
Make your knob yourself with Plastimont bodies !
Insert hex screw or nut made of steel, stainless steel, brass, nylon or other material.
Usable screw length once assembly is made = screw length minus “h”.
Example of assembly with a screw M8 x 20 mm : usable screw length = 20 mm - 2,5 mm = 17,5 mm.
