Need to replace the bolts for the traier hitch. (dont ask) The Toyota supplied bolts have a hex flange built in to them. Is a metric grade 8 bolt with grade 8 washer just as strong? Having trouble finding the flanged bolts.

Thanks.
Actually went to Hillco fasteners and they set me up with grade 8 bolts and washers. Everything is fine now. They were surprised that the supplied bolts were only grade 5.

I need to ask....Did they shear off?

I tow a travel trailer and if the stock ones are only grade 5, I best be changing them mucho pronto.

The reason I changed them was when I was installing the hitch, I could not get the stock bolts to sinch at 80 ft lbs. I pulled the bolts out and found that 1 was stretching. The new grade 8 bolts tightened up perfectly. (yes, I have a fresh, well maintained torque wrench)


This is the 3rd FJ hitch I have installed and had no issues with the 2 before.
