Wood as An Engineering Material: Fastenings

COURSE NO: S03-019
COURSE PROVIDER: Gilbert Gedeon, P.E.
Wood as An Engineering Material: Fastenings
Course Highlights

This online engineering PDH course provides guidance on joint designs required for wood fastenings for utmost rigidity, strength, and service. It discusses each type of fastening requiring joint designs adapted to the strength properties of wood along and across the grain and to dimensional changes that may occur with changes in moisture content.


The strength and stability of any structure depend heavily on the fastenings that hold its parts together. One prime advantage of wood as a structural material is the ease with which wood structural parts can be joined together with a wide variety of fastenings such as nails, spikes, screws, bolts, lag screws, drift pins, staples and metal connectors of various types.


This 3 PDH online course is applicable to civil, structural or geotechnical engineers, as well as design and construction personnel who are interested in gaining a better understanding in wood fastenings or who are involved in the design and planning of wood structures.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about the various types of mechanical fastenings
  • Understanding the withdrawal and lateral resistance properties for different types of fasteners
  • Learning about joint designs required for wood fastenings including spacing, edge and end distances
  • Understanding the effect of fastenings on wood joint properties including bearing stress
  • Understanding the different types of loading (parallel-to-grain, perpendicular-to-grain, and angle loading)
  • Learning about two-member joints versus multiple-member joints


Course Document
In this professional engineering CEU course, you need to review Chapter 8, "Fastenings" of the United States Department of Agriculture (USDA) Publication, “Wood Handbook - Wood as An Engineering Material”, FPL-GTR-190.
