Replacement nuts and bolts are available, contact Dixon for more information. 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. See page 704 for Fraction to Decimal conversion chart. Recommended torque rating in ft. lbs.
Features: A leakproof seal is formed when the metal head of the stem makes contact with the patented polymer seat in the spud. The non-metallic polymer seat resists most chemicals found in manufacturing facilities. (reference corrosion resistance chart on pages 694-699). Recommended for steam service up to 450°F. Easy to seal. Works with existing fittings. Plated steel and / or iron. Use with Boss clamps found on pages 99 and 100.
Use with Boss clamps on pages 99 and 100. For safety tags and safety tape see page 672.
