American Wood Council Notes NDS Changes to Nail Withdrawal Testing

January 30, 2018 By IIBEC Communications

The National Design Specification for Wood Construction (NDS®), published by the American Wood Council, has made changes with respect to the withdrawal (pullout) values of nails in wood and wood products. The International Staple, Nail, and Tool Association (ISANTA) has published an advisory on the changes. In the 2018 edition, there were five areas of change with regards to nail withdrawal:

  • A clarification to the Post Frame Ring Shank nail withdrawal values
  • A clarification in the design values for carbon steel nails
  • Addition of design values for stainless steel nails

To learn more about the particulars of the changes, visit bit.ly/2D4t85t. A presentation on the changes
