The Design & Analysis of Fasteners & Bolted Joints

About the Seminar  Download Seminar Brochure Download Seminar Syllabus
Threaded fasteners are a notable cause of service and other related problems. Besides possible safety implications, fastener failures can represent a significant proportion of a product's warranty costs. This training seminar presents key knowledge and facts to an Engineer to enable bolted joints to be designed and fasteners sized so that they will not fail. A training course handbook is provided to all delegates. The handbook contains background information to the material presented on the course together with tables of thread stress areas, thread shear areas and fastener material strength details.

Who Should Attend
Since most manufactured products involve the use of fasteners for assembly, this seminar is very beneficial to professionals working on design and development, maintenance, and procurement of fasteners and bolted interfaces. If you are involved in design engineering, manufacturing and assembly, standardization, testing, quality control, or otherwise involved with technical aspects of fasteners, this course is designed especially for you.

About the Instructor

Bill Eccles's original background was in Design Engineering. Prior to forming his own company, he worked on vehicle and construction machinery design for a number of companies and was an Engineering Manager for two multi-national companies. Bill formed Bolt Science in 1992. The company is a provider of independent technical expertise in bolted joint technology. It has become one of the leading sources of advice in this field and the company's clients include many of the major engineering organizations of the world. Bolt Science's software products are used globally. Bill has extensive experience in the design, analysis and installation of bolted joints and has published a number of technical papers on the subject. The work he has completed includes, among other things, fastener and joint failure investigation and the determination of its causes into a number of catastrophic accidents. His experience covers the automotive, marine, aerospace, plant and machine tool industries. He has a number of degrees including a doctorate on the self-loosening of threaded fasteners and has delivered training courses around the world on the analysis of bolted joints and bolting technology.
