Download or read book Protective Coatings for Fasteners written by Fasteners Committee and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Information Report is provided as an advisory guide. Careful discretion as to application is recommended. The content has been presented as accurately as possible, but responsibility for its application lies with the user. It covers finishes applied to fasteners and related topics, corrosion resistance, lubricity, electrical grounding, ultraviolet light, and embrittlement.Table 1 lists these coatings and their properties so that finish selection can be reasonably made in accordance with known and anticipated fastener assembly applications.Application of protective coatings will affect fastener dimensions. This is especially critical for the thread fit of mating parts because the pitch diameter increases by four times the coating thickness. Explanation is covered in Section 5. This Information Report covers technology, products, or processes for which technical expertise no longer resides in the owning committee. Current finish specifications for additional information include the following: ASTM F1941/1941M (Standard Specification for Electrodeposited Coatings on Mechanical Fasteners, Inch and Metric); ASTM F2833 (Standard Specification for Corrosion Protective Fastener Coatings with Zinc Rich Base Coat and Aluminum Organic/Inorganic Type); ASTM F3019/F3019M (Standard Specification for Chromium Free Zinc-Flake Composite, with or without Integral Lubricant, Corrosion Protective Coatings for Fasteners); ISO 4042 (Fasteners - Electroplating Systems), ISO 10683 (Fasteners - Non-Electrolytically Applied Coatings), ISO 10684 (Fasteners - Hot Dip Galvanized Coatings), ISO 16048 (Passivation of Corrosion-Resistant Stainless-Steel Fasteners), and ISO 11408 (Chemical Conversion Coatings - Black Oxide Coating on Iron and Steel - Specification and Test Methods).

Download or read book Fastener Design Manual written by Richard T. Barrett and published by . This book was released on 2011-07-27 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual was written for design engineers to enable them to choose appropriate fasteners for their designs. Subject matter includes fastener material selection, platings, lubricants, corrosion, locking methods, washers, inserts, thread types and classes, fatigue loading, and fastener torque. A section on design criteria covers the derivation of torque formulas, loads on a fastener group, combining simultaneous shear and tension loads, pullout load for tapped bales, grip length, head styles, and fastener strengths. The second half of this manual presents general guidelines and selection criteria for rivets and lockbolts. To the casual observer the selection of bolts, nuts, and rivets for a design should be a simple task. In reality it is a difficult task, requiring careful consideration of temperature, corrosion, vibration, fatigue, initial preload, and many other factors. The intent of this manual is to present enough data on bolt and rivet materials, finishes, torques, and thread lubricants to enable a designer to make a sensible selection for a particular design. Lockouts, washers, locking methods, inserts, rivets, and tapped holes arc also covered. Bolts can be made froni many materials, but most bolts are made of carbon steel, alloy steel, or stainless steel. Stainless steels include both iron- and nickel-based chromium alloys. Titanium and aluminum bolts have limited usage, primarily in the aerospace industry. Carbon steel is the cheapest and most common bolt material. Most hardware stores sell carbon steel bolts, which are usually zinc plated to resist corrosion_ The typical ultimate strength of this bolt material is 55 ksi. An alloy steel is a high-strength carbon steel that can be heat treated up to 300 ksi. However, it is not corrosion resistant and must therefore have some type of coating to protect it from corrosion. Aerospace alloy steel fasteners are usually cadmium plated for corrosion protection_ Bolts of stainless steel (cREs) are available in a variety of alloys with ultimate strengths from 70 to 220 ksi. The major advantage of using CRES is that it normally requires no protective coating and has a wider service temperature range than plain carbon or alloy steels. A partial listing of bolt materials is given in table 1. The following precautions are to be noted: (1) The bolt plating material is usually the limiting factor on maximum service temperature. (2) Carbon steel and alloy steel are unsatisfactory (become brittle) at temperatures below -65 'F. (3) Hydrogen embrittlement is a problem with most common methods of plating, unless special procedures are used. (This subject is covered more fully in the corrosion section.) (4) Series 400 CRES contains only 12 percent chromium and thus will corrode in some environments, (5) The contact of dissimilar materials can create galvanic corrosion, which can become a major problem. (Galvanic corrosion is covered in a subsequent section of this manual.) Platings and Coatings Most plating processes are electrolytic and generate hydro-gen. Thus, most plating processes require baking after plating at a temperature well below the decomposition temperature of the plating material to prevent hydrogen ernhrittlernent. However, heating the plating to its decomposition temperature can generate free hydrogen again. Thus, exceeding the safe operating temperature of the plating can cause premature fastener failure due to hydrogen embrittlement as well as loss of corrosion protection. (A summary of platings and coatings is given in table II.) Cadmium Plating The most common aerospace fastener plating material is cadmium. Plating is done by electrodeposition and is easy to accomplish. However, cadmium-plated parts must be baked at 375 "F for 23 hours, within 2 hours after plating, to prevent hydrogen embrittlement. Since cadmium melts at 600 "F, its useful service temperature limit is 450 'F.

Download or read book Handbook of Bolts and Bolted Joints written by John Bickford and published by CRC Press. This book was released on 1998-04-28 with total page 930 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting time-tested standard as well as reliable emerging knowledge on threaded fasteners and joints, this book covers how to select parts and materials, predict behavior, control assembly processes, and solve on-the-job problems. It examines key issues affecting bolting in the automotive, pressure vessel, petrochemical, aerospace, and structural steel industries. The editors have successfully created a useful rather than scholarly handbook with chapters written in a straightforward, how-to-do-it manner. Theory is discussed only when necessary and the handbook's logical organization and thorough index enhances its usefulness.
