Threaded Fasteners
Threaded Fasteners Introduction If you are designing and building a Formula SAE vehicle, threaded fasteners will likely be used to join the various components and systems together and allow the vehicle to function as a unified machine. The reliability of your vehicle is key to realize your potential at the competition. Even though threaded fasteners have been in use for hundreds of years and are in products that we use every day, their performance is dependent on a wide range of factors. This chapter covers some of the main factors that can influence reliability and is intended as an aid in joint design, fastener selection, and installation. The first portion of this chapter covers several design and installation factors that can work together to improve the reliability of your vehicle’s bolted joints. These topics include, the importance of generating and maintaining clamp load, and how clamp load, along with joint stiffness, can work together to prevent self-loosening and improve fatigue performance. The second portion of this chapter reviews how installation method and torque are related to clamp load, and also includes a comparison between common fastener types to aid in selection. The chapter concludes with a short tutorial showing how to obtain Mil Spec information on fasteners and similar hardware. Disclaimer – Multiple factors on each component in a bolted joint affect its performance. Additionally, service requirements for every joint differ. Each joint must be evaluated and tested for its ability to perform the desired function. The information in this chapter provides general background and does not represent how a specific design or piece of hardware will perform. -

Maclean ESNA's Catalog
611 COUNTRY CLUB ROAD POCAHONTAS, ARKANSAS 72445 SALES: 1-(800)-331-6469 FAX: 1-(870)-892-8938 WWW.MACLEANFOGGCS.COM 1 The ESNA® story began in 1927, when a young engineer named Carl Arthur Swanstrom came to this country from Sweden. He brought with him a license to manufacture and sell a unique new self-locking fastener. The Inventor called the new fastener an “Elastic Stop® nut” because the nut remained “stopped” anywhere along the bolt threads. A non-damaging insert, fitted into the top of the nut, gripped the bolt threads firmly, holding the nut in position without seating against the work or using secondary locking devices. The only problem with the new nut was the inability to mass-produce them. The next few years were spent perfecting an automatic assembly machine to insert the locking device into the top of the nut. Swanstrom perfected the machine in the early 1930s and only four years later the Elastic Stop® Nut Corporation of America was founded. A threaded fastener, able to positively resist the loosening effect of vibration, had long been sought by manufacturers of every type of equipment. The Elastic Stop® nut proved to be the answer — totally reliable, able to reduce maintenance costs and prevent equipment failure. The outstanding performance of the Elastic Stop® nut was further substantiated in 1943 when the Air Force tested and issued the first approval letter to use ESNA® fasteners on military aircraft, both fuselage and engines. During WWII billions of Elastic Stop® nuts were produced for every branch of the armed services. -
Self-Clinching Nuts Install Permanently in Aluminum, Steel Or Stainless Steel Sheets
PEM® brand self-clinching nuts install permanently in aluminum, steel or stainless steel sheets. CL™ SELF-CLINCHING NUTS SELF-CLINCHING NUTS Self-clinching nuts are installed by placing them in properly sized holes in sheets and applying a parallel squeezing force to the head of the nut. The sheet metal surrounding the head cold flows into an undercut thereby making the fastener an integral part of the sheet. A serrated clinching ring prevents the fastener from rotating after installation. S™/SS™/CLA™/CLS™/CLSS™ nuts H™ (non-locking) and HNL™ (locking) provide load-bearing threads in thin nuts have threads that provide high sheets with high pushout and torque-out pushout and torque-out resistance - resistance - PAGES 4 and 5 PAGE 8 SP™, PEM 300® nuts provide strong SH™ hard panel nuts install into thin, load-bearing threads in stainless steel harder, high strength steel materials - sheets as thin as .030”/0.8 mm - PAGE 8 PAGES 4 and 5 SMPS™/SMPP™ nuts are for thinner PEM RT® free-running locknuts are sheet/close-to-edge applications - free-running until clamp load is induced.

Onshape: Nut and Bolt Tutorial By: Matthew Jourden Brighton High School Brighton, MI
OnShape: Nut and Bolt Tutorial By: Matthew Jourden Brighton High School Brighton, MI Objective: Design a Commercially Off Shelf (COTs) Nut and Bolt with a detailed thread. COTs Parts are considered to be standardized parts. Parts like nuts, bolts, screws, washers, cotter pins, woodruff keys, etc. are standardized based on one measurement. An engineering can gather the necessary resources from a variety of manuals like Machinery Handbook, ANSI or ISO manuals or Appendix on a Engineering Textbook (see below). The various measurements of fasteners will typically be a factor of the Major Diameter of the Thread. Utilizing reference charts (see below) will save the engineer time in having to calculate out the various measurements of a fastener.
