ICC-ES AC500 – Acceptance Criteria for Self-drilling Tapping Screws Used to Attach Miscellaneous Building Materials to Steel Base Material

Scope

ICC-ES AC500 outlines the acceptance criteria for self-drilling tapping screws (SDTS) used to attach miscellaneous building materials to steel base material in construction. It focuses on:

  • Material requirements: specifies the chemical composition, mechanical properties, and corrosion resistance requirements for the screws and their coatings.
  • Design and construction: outlines the dimensional and geometric requirements for the screws, including thread form, point type, and head style.
  • Performance requirements: establishes minimum performance criteria for the screws, such as pullout strength, shear strength, and torque-tension relationship.
  • Testing procedures: details the standard test methods to assess the mechanical properties and performance of the screws in steel substrates.
  • Quality control: requires manufacturers to have quality control programs in place to ensure consistent product quality and adherence to the acceptance criteria.

By adhering to AC500, manufacturers and users can ensure that self-drilling tapping screws used to attach miscellaneous building materials to steel meet the necessary performance and safety requirements.
