ASTM F606: Standard Test Methods for Determining the Mechanical Properties of Externally Threaded Fasteners
ASTM F606 is the standard test method for determining the mechanical properties of externally threaded fasteners, including bolts, screws, and studs. This standard provides a comprehensive approach to evaluating the strength, ductility, and other critical properties of fasteners used in various applications, ensuring that they meet performance requirements for safety and reliability.
This webpage provides an overview of ASTM F606, but it is recommended that users refer to the full ASTM F606 standard for complete details on procedures and requirements.
ASTM F606 Properties of Interest
The primary properties measured in ASTM F606 include:
Tensile Strength: The maximum load that a fastener can withstand when pulled before breaking, typically expressed in pounds per square inch (psi) or megapascals (MPa).
Yield Strength: The stress at which a fastener begins to deform plastically, indicating its ability to retain its shape under load.
Elongation: The percentage of elongation that occurs before fracture, providing insight into the ductility of the fastener material.
ASTM F606 Testing Setup and Method
Testing in accordance with ASTM F606 requires specialized equipment:
Universal Testing Machine (UTM): Used to apply controlled loads to the fasteners during tensile testing, measuring load and elongation.
Load Cells: These measure the force applied and the specimen's deflection, respectively, ensuring high precision in test data
Bolt Tensile Grips and Inserts: These grips are designed to securely hold bolts, studs, screws, and nuts during tensile testing.
