Torqued M8 x 1.25 30 mm Long Class 12.9 Seat Mounting Bolt Kit BM830

Made of zinc-plated alloy steel and with a tensile strength of 170,000 psi, these Class 12.9 bolts can be use to mount Tillett Seats. The length of the threads is 30 mm and at least 10 mm of thread should be in the seat to mount it securely. Do not exceed 20 mm though, so be sure to buy the right length of bolts for your configuration. We also recommend running fender washers in most applications. Comes as a pack of 4 kit for one seat.
