Expert Reply:
The attachment bolts for a 5-bolt brake assembly should be torqued to 30-50 foot/lbs. This will ensure your brake assembly # AKEBRK-7-SA is secured correctly.
If you don't have a torque wrench, I recommend the Powerbuilt Dual Drive Torque Wrench - 3/8" and 1/2" - 10 to 150 ft-lb # ALL944001.

Jameson, I decided to go with the Hydrastar Trailer Brakes - HSE7K-T1 and have run into a problem. I'm mounting the caliper mounting plates. In attempting to torque the nuts to the recommended 50 foot/lbs, I have striped three nuts. The problem appears to be that the plate is thicker than the old drum brake plate and when the nuts bottom out that there is not enough threads in the nuts engaged with the bolt threads. And when attempting to torque the nuts, they are stripping. Have you seen this problem before? Any suggestions? The axles are 7000lb Dexter.
