ASTM D1761

Full Name

ASTM D1761 – Standard Test Methods for Mechanical Fasteners in Wood and Wood-Based Materials

Scope

ASTM D1761 outlines the procedures for evaluating the performance of mechanical fasteners, such as nails, staples, screws, bolts, and connectors, in wood and wood-based materials. The standard covers two main types of tests:

  • Direct withdrawal resistance: this test measures the force required to pull a fastener straight out of the material. It assesses the holding power of the fastener and the material’s resistance to splitting or other failure modes.
  • Lateral resistance: this test measures the force required to move a fastener sideways (perpendicular to the direction of insertion). It evaluates the fastener’s ability to resist lateral loads and the material’s resistance to shear failure.

The scope of ASTM D1761 includes:

  • Materials: the standard applies to various wood and wood-based materials, including solid wood, plywood, oriented strand board (OSB), and composite wood products.
  • Fastener types: it covers a wide range of mechanical fasteners used in wood construction, including nails, staples, screws, bolts, and connectors.
  • Test procedures: the standard provides detailed procedures for conducting both direct withdrawal and lateral resistance tests, including specimen preparation, testing apparatus, and data analysis.
  • Applications: the test results can be used for various purposes, such as:
    • Product development: evaluating the performance of new fastener designs and materials.
    • Quality control: ensuring the quality and consistency of fasteners during manufacturing.
    • Design: providing data for the design of wood structures and connections.
    • Research: investigating the behavior of fasteners in wood under various loading conditions.

ASTM D1761 is a valuable resource for engineers, architects, builders, and manufacturers who work with wood and wood-based materials. The standard helps ensure that fasteners are selected and installed correctly to provide safe and reliable connections in wood structures.
