03Technical description

The Hex Bolt ASTM A490 Black is a hex head bolt for wrench tightening, used in bolted structural joints, steel erection and connections where the drawing requires an ASTM specification. TECTUL offers it in carbon steel, with UNC inch thread and ASTM A490 specification associated with ASTM A490. Correct selection depends on diameter, length, thread pitch, finish, compatible nut and actual service condition. The black finish differentiates it from black, zinc-plated or stainless references in the same family. In industrial purchasing it is advisable to validate whether the drawing requires full or partial thread, whether the assembly works under vibration, whether there will be outdoor exposure and whether material certificate or lot traceability is required.

Installation recommendations

  • Confirm that the nut and washer match the same thread system, grade and finish as the bolt.
  • Clean the threads before installation and avoid forcing thread start when there is misalignment.
  • Apply the torque defined by the designer, the installation procedure or the project standard; do not use a generic value without validating lubrication and surface condition.
  • In humid or outdoor environments, check whether the black finish needs additional protection or whether zinc-plated, galvanized or stainless steel is suitable.
  • When the joint is structural or critical, do not substitute grade, standard or length without technical approval.
