I purchased a Demco Hydraulic Trailer Brake Actuator - Drum Brakes - Zinc Plated - 2inch Ball - 7,000 lbs- Item # DM72VR..The install video says Buy grade A bolts. Can you let me know the specific bolt size and length? Thanks !


Helpful Expert Reply:

The bolts that you need to install your Demco Hydraulic Trailer Brake Actuator # DM72VR are 1/2 x 4-1/2 inch Grade 5 bolts and it is recommended to use a steel bushing on the interior of the frame to protect it from any over tightening that can damage your trailer frame. You can find these bolts at any local hardware store.
