Fasteners are crucial for building design, especially in extreme climate areas such as hurricane or earthquake zones. In any design, however, fastener strength can often determine the viability of a project. Whether you are concerned about bending strength, corrosion, resistance, or shear, we can provide the fastener testing necessary to address your concerns.

ICC-ES accredited laboratories conduct tests for various types of fastener products, including but not limited to:

• Mechanical testing in wood and plastic lumber
• Nails, staples, screws, lag bolts
• Bending strength and stiffness
• Fastener withdrawal resistance
• Fastener pull-through resistance
• Lateral resistance
• Sample prep and lumber conditioning
• Bolted and Timber connection joints
• Plate-type connector joints
• Joist hanger

We work to create tailored test plans that capture specialized requirements for innovative products, such as those found in the ICC-ES Acceptance Criteria. Test plans help ensure your innovative product has a clear path through the certification process with agreement from all participants. Below is a list of standards or criteria that may be included in test plans for fastener products:

• ASTM D1761: Standard Test Methods for Mechanical Fasteners in Wood
• ASTM E489: Standard Test Method for Tensile Strength Properties of Metal Connector Plates
• ASTM E767: Standard Test Method for Shear Strength Properties of Metal Connector Plates
• ASTM F1575: Standard Test Method for Determining Bending Yield Moment of Nails
• TPI 1: National Design Standard for Metal Plate Connected Wood Truss Construction
• CSA S347-14: Method of Test for Evaluation of Truss Plates Used in Lumber Joints
• ICC-ES AC13: Joist Hangers and Similar Devices
