The clearance hole and counter bore for the Unbrako fastener should be made with minimum clearance to preserve strength.

5.

Treat the threads with Loctite when assembling to prevent the parts becoming loose with use.

6.

Unbrako fasteners should be used as they give great strength combined with small size.
