Title: Brake disc to front bearing hub bolts T/C
Post by: kram350kram on Wednesday,August 05, 2020, 08:14:44 PM: In changing the brake disc rotors I noticed the 4 retaining bolts had two raised lines on their heads crossing at 90 degrees. Have never seen this making and can't find anywhere except standard AN aircraft bolts have a somewhat similar marking. Anyone know what these bolts are, (grade 6 maybe?). Worth changing to grade 8 while here? Thanks in advance.
