Genuine Multivator blade bolt and locknut. The Multivator blade bolt has a special shoulder section eliminating any potential shear point between the flange and the blade threads. The blade bolt is mated with a shakeproof washer so the nut will not back off during use. This is a fine thread bolt, special metric grade 10.9.
Note: this item is supplied in a pack of 8 bolts & nuts, enough to complete one blade flange.
