Specifications and dimensions of expansion bolts for distribution boxes
The length of the bolts should account for the depth of the wall (75-150 millimeters), the thickness of the box's base, and the thickness of the nut and washer, plus an additional 5 millimeters for clearance. Conventio-nal fitted bolts are traditionally used in order to transmit the greatest possible transverse forces through positive locking. This contradicts the interpretation of the connection, which assumes order to press-fit bolts. 3 Strength Design nized coating, 304 stainless steel and 316 stainless steel versions.
