Flywheel and Pressure Plate Bolts
At Direct Clutch Services we stock a large range of grade 12.9 , metric and imperial bolts used in clutch flywheels and pressure plates.
We also stock common ARP bolt sets.
Note: the lubricant supplied with some ARP bolts is to be used under the bolt head only. Thread locker can be used on the threads.
Special note: Many of the older flywheels do not run modern style dowels. Instead these units required a bolt with a specific shank .
Failing to run these correct shank bolts, not only can cause an imbalance with the clutch, but can also see the clutch cover able to move off centre. VERY DANGEROUS!

Mazda Rotary Bolts
We also carry the genuine Mazda Rotary specific bolts.
Genuine Mazda rotary M8 x 1.0mm grade 10 bolt set for all NON turbo 215mm pressure plates:
Important note:
All Mazda Rotary 8.5 – 215mm pressure plates require 2 shanked bolts as this era unit does not run modern type dowels.
Instead precise location of the pressure plate is made by the shanked area of bolt, locating into a non threaded area of 2 bolt holes in the flywheel only.
Failing to run shanked bolts may result in clutch failure, damage to vehicle or injury!
Also available with M8 Safety washers.
Recommended torque setting of 22nm.
