Metal Clevis M3 x 31mm pack of 10 with Retainers
A bag of 10 hardened Metal Clevis M3 thread (3mm)
Pin diameter 1.6mm which fits all standard output arms and horns.
10 in a pack comes and with rubber retainers.
Although metal clevises are not so prone as to coming open as nylon ones are, it is still wise to take the precaution of sliding a short length of silicone tubing (AKA retainer ) over the pushrod before fitting the clevis. Once the clevis is located in the horn, slide this tubing over the clevis jaws to help prevent them parting inadvertently during flight (see additional image).
