Well, most of the threaded fasteners used in general applications have the following disadvantages:
1. Continued exposure to vibration tends to loosen the fastener.
2. If the fasteners are not creep resistant, they will fail at elevated temperatures.
3. The sharp edges formed in the threads of the members acts as stress concentration regions and is undesirable. This is to some extent overcome by introducing a small radius at the crests and troughs of the threads.

What is GM 500 M 9.8 screw?
GM500M: Mechanical and Material Requirements for Metric Externally Threaded Fasteners. This standard covers the mechanical and material requirements for six property classes of carbon and alloy steel externally threaded metric fasteners in nominal thread diameters M1.6 to M36, inclusive, suitable for use in general engineering applications. Products included are bolts, screws, studs, U-bolts and sems and hardness of HRC39 max. Tapping screws, thread rolling screws, self drilling tapping screws and set-screws are NOT included. The term "stud" as referred to herein applies to a cylindrical rod of moderate length, threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared or similar products which are more closely characterized by requirements shown herein for bolts. For specification purposes, this standard treats U-bolts as studs. Thus, wherever, the word "studs" appears, "U-bolts" is also implied. U-bolts covered by this standard are those used primarily in the suspension and related areas of vehicles. (Designers should recognize that the "U" configuration may not sustain a load equivalent to two bolts or studs of the same size and grade; thus actual load carrying capacity of U-bolts should be determined by saddle load tests.) Requirements for the 6 property classes, 4.6, 4.8, 5.8, 9.8, and 10.9 are essentially identical with requirements given for these classes in ISO 898/1 and ASTM F568.

What is a threaded metal rod?
A threaded metal rod is a long, straight piece of metal with helical ridges or threads running along its length. It is typically used to fasten or secure objects together by twisting nuts or other fasteners onto the threaded portion. It is commonly used in construction, manufacturing, and DIY projects.
How far back in time does the fastener industry go?
In the fifteenth century threaded fasteners began to appear in common usage. In this century, the first printing press was held together and run by a screw.
What is the main disadvantage of Luque rods?
The main disadvantage is that the risk of injury to the nerves and spinal cord is higher than with a some other forms of instrumentation. This is because wires must be threaded through each vertebra near the spinal column.
List three uses of threaded fasteners?
1. they are used in making furniture ( couches/chairs ) 2. they are used to hold parts of machines together 3. they are also used in bikes to hold the seat etc.
What is the advantage of using threaded fasteners to secure structural components as opposed to welding or adhesives?
It is easier to remove something screwed in than something glued or welded in. Further threaded fasteners go deeper than adhesives, giving more of the object to hold onto than just the surface areas. This is good for anything attaching to wood which is a softer material. Stainless steel doesn't weld too well, particularly to non-stainless steel, so fasteners may prove an easier alternative. As I heard that stainless steel is cheaper it can save money as well. Different types of metal or even different thicknesses of a metal can be hard to weld or just may not be weldable at all and so fasteners are needed. Sometimes a weld can can be brittle and snap or an adhesive wear away from small movements. Fasteners can be more reliable if you're not a pro. Fasteners can be cheaper as well in many circumstances. A drill is usually cheaper than a MIG Welder. lol.
What are the principal categories of industrial fasteners, and what do they find applications for?
The main industrial fastener categories are: Bolts: Threaded fasteners employed with nuts to assemble materials. Widespread in construction and machinery. Nuts: Fasteners employed in conjunction with bolts to secure them. Applied in automotive and machinery. Screws: Threaded fasteners directly driven into materials. Applied in wood, metal, and plastic. Washers: Flat pieces inserted underneath bolts or nuts to spread pressure. Applied in machinery and the automotive industry. Rivets: A type of fastener that is permanent and joined materials by distorting the ends. Used in aerospace and building. Pins: Cylindrical fasteners used to pin parts together. Applied in machinery and automotive applications. Anchors: An object that attaches objects to masonry or concrete. Used most in building construction. Clips: Small devices that snap to retain components in place. Utilized in motor vehicle and electric industries. All these fasteners are used to hold and keep parts together across industrial applications.
What are the main types of fasteners?
Screws, bolts, nuts, washers, rivets, nails, and pins are some of the different types of fasteners. Screws and bolts are threaded fasteners used to assemble objects; screws are often used with pre-drilled holes, while bolts come with nuts. Nuts and bolts form secure connections, while washers spread the weight and prevent damage. Rivets are permanent fasteners used in structural applications. Nails are generally employed in woodworking, whereas pins, such as cotter pins, hold items in place. Each kind performs a distinct role depending on the assembly's requirements.
