April 29 - May 1, 2025 8am-4pm CST Fundamentals of Threaded Fasteners and Joint Design
Course Overview
The course will give participants an in-depth explanation of fastener terminology, technology, and threaded fastener joint design calculations and strategies. This will enable the student to design the joint and select the proper threaded fasteners so the system will not fail in service. The course will include case studies, problems that will be solved during class and a demonstration of preload scatter achieved through torque tightening. The Simplified Bolted Joint Design Guideline summarizes all critical calculations, which defines a systematic method for evaluating most bolted joints for the common failure modes.
The focus of the course will be on dynamically loaded fastened joints rather than structural joints, according to AISC 360. Although the VDI-2230 standard will often be referenced, the course is not intended to provide a detailed presentation of this standard.
Target Audience
This course was developed for engineers or technical staff tasked with the design, specification, procurement, quality, or assembly of threaded fastened joints.
Prerequisites
This is an intermediate technical level course that includes equations that need to be solved with algebra. Individuals with some prior experience with fasteners and bolted joint design may find this course easier, but there is something everyone can learn from it.
In-Person or Online Learning
Students may choose to attend in person or via a live online stream concurrent with the in-person training. The in-person session will be held in the training facilities at Matrix Engineering Consultants, 12986 Valley View Road, Eden Prairie, Minnesota 55344.
Professional Development Hours (PDHs)
The three-day in-person and online learning event is worth 21 PDHs.
Students who solve the supplemental learning exercises and participate in the follow-up webinar to review the results will receive an additional 3 PDHs.
