Subject: [FlyRotary] FWF Bolts---General Advice
Is there is benefit to using the flange type bolt heads (stock mazda) instead of using a regular or socket head bolt with the proper washer. I am ready to mount the redrive and need to purchase bolts for the flexplate. The local mazda dealer has them in stock but would like to charge me $30 for the set. Grade 12.9 socket head bolts are less than a $1 each with washer.
Any opinions?
Bobby
Bobby, The flange heads are a little more resistant to torquing out due to the flange. Otherwise the same.
