Fastener Loads for Plywood - Screws

The integrity of a structure is frequently dependent upon the connections between its component elements. For maximum strength and stability, each joint requires a design adapted to the fastener type and to the strength properties of the individual structural members.

This publication is designed for: designers, architects

This publication contains several tables with values for ultimate withdrawal and ultimate lateral loads for plywood joints fastened with wood screws and sheet metal screws. The values in these tables are based on tests conducted on plywood by APA.

Key sections include:

• Test results for panel-and-metal connections

  • Lateral resistance, metal to plywood

  • Lateral resistance, plywood to metal

  • Withdrawal resistance, metal to plywood

  • Withdrawal resistance, plywood to metal

  • Lateral resistance, plywood-to-plywood into panel edges

• Estimating allowable design loads
