The S-5-U clamp was designed for application like Mechanical seam and profile similar.

For maximum holding strength, setscrews should be tensioned and re-tensioned as the seam material compresses. Clamp setscrew tension should be verified using a calibrated torque wrench between 160 and 180 inch-pounds when used on a 22-gauge steel, and between 130 and 150 inch-pounds for all other metals and thinner gauges of steel.
