Geometric Dimensioning and Tolerancing for Fasteners Co-Produced by Industrial Fasteners Institute and Fastener Training Institute DATES Tuesday and Wednesday, May 27-28, 2026 TIME 9:00 a.m. - 4:00 p.m. ET LOCATION IFI Headquarters 6363 Oak Tree Blvd. Independence, OH 44131 INSTRUCTOR Laurence Claus, IFI Director of Education and Training COURSE OVERVIEW One of the most misunderstood themes between fastener manufacturers and customers is the application of geometric dimensions and tolerances (GDT) on prints. Often, because customers do not understand the fastener manufacturing process, GDT is applied in a manner that is burdensome to suppliers. Likewise, because manufacturers often fail to appreciate customer needs for a particular feature to function in a certain way, GDT is viewed as burdensome and problematic. This two-day, interactive seminar educates and familiarizes students with a basic understanding of GDT, specifically related to its use on threaded fasteners. We explore how specific geometric characteristics are used to describe fit, form and function on threaded fasteners. CURRICULUM INCLUDES The session includes approximately ten segments, helping students become familiar with and build skill levels in basic GDT concepts. Each segment has associated group exercises. Some segments include: • Identifying datums • Understanding the meaning of GDT symbols • Reading the feature control frame • Bonus tolerance • Measuring GDT requirements WHO SHOULD ATTEND This class is beneficial to many in the fastener industry, including: • Manufacturing and process engineers • Quality engineers and technicians • Manufacturing leads • Quoting and estimation associates • Technical sales • Anyone who would like to learn more about fasteners PRICING This is a two-day class. Early bird pricing is available for $1150 for both days. The price increases to $1350 on May 13, 2026. The class is FREE for IFI Members. Continental breakfast and lunch are provided each day.
