ICC-ES AC499
Full Name
ICC-ES AC499 – Acceptance Criteria for Screw-in Fasteners Installed into Steel Elements
Scope
ICC-ES AC499 establishes the requirements and guidelines for evaluating the performance and suitability of screw-in fasteners (SIFs) used in steel elements for construction. The scope of AC499 covers various aspects, including:
- Types of fasteners: the criteria apply to carbon steel and stainless steel screw-in fasteners, encompassing various designs and head styles.
- Installation: AC499 covers SIFs installed into steel elements, including hot-rolled and cold-formed steel sections, and evaluates their performance under different installation conditions.
- Performance requirements: the criteria outline the performance requirements for SIFs, including tensile strength, shear strength, combined tension and shear strength, and resistance to pull-out and pull-over failure modes.
- Test methods: AC499 specifies the standard test methods to assess the performance of SIFs, including static and fatigue loading tests, to ensure they meet the required safety and performance standards.
- Evaluation criteria: the document provides guidelines for interpreting test results and determining whether the SIFs comply with the acceptance criteria for safe and reliable use in building construction.
In summary, ICC-ES AC499 is a comprehensive technical guideline for evaluating screw-in fasteners installed into steel elements. It aims to ensure that these fasteners meet the necessary structural and safety requirements for their intended applications in buildings, contributing to the overall integrity and performance of the construction.
