•
The bolts used in the Boss interlocking clamps are not standard bolts. They vary from
standard bolts in their length, diameter, overall thread length and material hardness. These
bolts can be retorqued, but it is
not
recommended that the bolts or clamps be reused, as
they are designed for a single bend only. Dixon recommends using only factory supplied
replacement bolts.
•
Torque values for clamps are based on dry bolts. The use of lubricant on bolts will adversely
effect clamp performance.
Do not lubricate nuts and bolts.
•
recommended for steam service up to
450
°F
•
recommended torque rating in ft. lbs.
•
replacement nuts and bolts are available, contact Dixon for more information
