What type of bolts used for motor mounts??

I am trying to replace bolts that hold my kodiak brake calipers. After 4 yrs I replaced the pads and all the kodiak parts look great and well worth the cost for stainless steel. The bolts though are a different story.



Now I need to figure out a type of bolt to use. What type of bolts do they use to mount the motors?? Mine are 7 yrs old and show no signs of rust

    Stainless steel.

    Is that a picture of a motor mount or a trailer?

    It is a picture of the hub and the caliper bracket for a koidak disc brake. The bolts are rusted and so is the axles arm. The arm is thick so not too concerned but the caliper bolts concerns me

    So , I spent a few hours to replace the rusted bolts. Basic zinc coated bolts. I replaced with SS bolts and lock washer. I pulled my original receipt, I paid an extra $500 for SS hardware. All visible bolts were SS but the ones I could not see without taking things apart were cheap zinc coated. I guess they figured I would have to remove rotor and caliper to see the bolts.

    Typical, cut corners and cheat the customer. I hope this trailer manufacturer goes belly up

    Are hose just holding the brakes on or something with more stress? Stainless is too brittle for most high strength applications.

    They just hold the brake caliper only so I do not think it needs to be that strong. I thought about galvanized also

    The two long bolts that hold the caliper is holding the caliper steady. The research I did the hex cap zinc grade 5 is about the same if not less than 18-8 SS same size in tensile strength

    I'm sure it's safe especially compared to rusty steel but I'd think shear strength is what those bolts see vs tensile. Again, how strong is a 1/2 rusted grade 5 anyway.
