8 mm Shaft Spiral Return Spring
A printed spiral torsion spring that returns an 8 mm shaft to its home position — the hub slip-fits an 8 mm rod (8.3 mm bore) and locks with an M3 set screw in a collar that sits 6 mm above the coils, while a 3-turn, 2.6 mm x 12 mm band winds out to a bolt pad with two M4 clearance holes on 16 mm centres. Overall 82 x 61 x 18 mm; good for flap/lever/pedal returns and damper hinges where a wound steel spring is a pain to source.
