Home Training Fundamentals of Threaded Fasteners and Joint Design

October 20 - 24th, 2025 M 1-6pm, Tu-Th 8am-4pm, Fr 8-11am, All times CST Fundamentals of Threaded Fasteners and Joint Design

Course Overview

This 5-day course equips engineers, designers, and technical professionals with the essential knowledge and hands-on tools to understand, specify, assemble, and troubleshoot threaded fasteners and bolted joints, with a focus on dynamically loaded mechanical bolted joints and preventing failures in real-world scenarios. It combines core engineering concepts with practical demonstrations and group problem-solving, diving deep into fastener terminology, technology, and in-class design calculations and strategies. Participants learn to design reliable joints through case studies, in-class exercises, and demonstrations of preload scatter and relaxation. Although the VDI-2230 standard will often be referenced, the course will not provide a detailed presentation of this standard. The class will conclude with a group capstone project, a realistic bolted joint that applies many of the concepts, methods, and calculations covered during the class.
