WebWorld's most comprehensive product line of bolting technology. TurnaSure manufactures the world's largest variety of Direct Tension Indicator Washers (DTIs). Our DTIs are used for achieving required tension loads on bolts in countless applications. These include Structural Steel Buildings and Bridges as well as DTI Washers for Studs used in the ... WebFasteners such as mine bolts are provided with tension indicators to directly read tension in the shank of the bolt. The preferred tension indicators comprise an elongated pin disposed in a bore formed in the bolt and connected at the bottom of the bore to the bolt shank to be tensioned thereby. The tension indicator further comprises a cross bar attached to the …

WebPart 9: System HR or HV – Direct tension indicators for bolt and nut assemblies; Part 10: System HRC – Bolt and nut assemblies with calibrated preload; Direct tension indicators (DTI) are equivalent to ‘load indicating … Web1 Nov 2024 · According to Hallwig, SmartBolts for injection molds typically have a Design Tension set at 35% to 45% of fastener proof strength, measured in kilopounds, though that figure sometimes has been as high as 60%. A lower Design Tension allows for longer bolt life and reduced platen thread wear, Hallwig notes. WebB. Direct tension indicator assemblies: The bolt, nut, washer and direct tension indicator shall be assembled into the calibrated bolt tension measuring device in the same configuration as is to be used in the work (See figure 2). Face plates, inserts and spacers with standard hole sizes shall be used. (Standard hole diameters are nominally 1/16” military intelligence corps march
