When replacing fasteners, it is generally best to match what you are replacing. Replacing a bolt with a stronger one is not always safe. Harder bolts tend to be more brittle and may fail in specific applications. Also some equipment is designed so that the bolts will fail before more expensive or critical items are damaged. In some environments, such as salt water, galvanic corrosion must also be considered if changing fastener materials.

Materials

Stainless Steel

Stainless steel is an alloy of low carbon steel and chromium for enhanced corrosion characteristics. Stainless steel is highly corrosion resistant for the price. Because the anti-corrosive properties are inherent to the metal, it will not lose this resistance if scratched during installation or use.

A lead screw is sometimes referred to as a “power screw” or a “translation screw”. They are used within motion control devices to transform rotary or turning movements into linear movements.

Lead screws are threaded bars of metal and a threaded nut which is in direct contact with the screw; this generates sliding friction as opposed to rolling friction from other alternative devices (such as a ball screw). Rotational motion will turn the screw, causing the nut to move along in a linear motion. This, therefore, converts the motion from rotary to linear.

They can be used for either vertical or horizontal movements and can use linear glides for support where necessary. They can be operated either manually or mortised depending on the application in hand.

Where the screw itself is generally constructed of stainless steel, the nut can be various materials depending on what is better suited for the application. Heavy-duty applications will require a metal nut whereas other applications may require a plastic one.

In this article, we will discuss the difference between nuts and bolts. The nuts and bolts are the types of fasteners that are used in every manufacturing industry to join two parts together. Here we will try to learn all the possible differences between nuts and bolts.

Difference between nuts and boltsWhat is Nut?

It is a type of fastener that has a threaded hole. It is used with the conjugation of a bolt. The two partners (i.e. nut and bolt) are held together by the combination of their thread frictions, slight stretching of the bolt and compression of the part to be joined together.

Aluminum plate is the most often used in the aerospace, transportation, and military industries for heavy-duty applications. A unique attribute of certain aluminum alloys is their ability to become stronger at extremely cold temperatures. Because of this, aluminum plate is used for the skin of spacecraft fuel tanks and jets, as well as storage tanks.

In addition, the high resistance to corrosion, its light weight, and its high strength, makes aluminum plate a common material for the structural sections of ships and railcars, as well as for military vehicle armor and even body armor..

Aluminum sheet and plate are widely used and in demand due to light weight, strength, high corrosion resistance, workability and versatility of aluminum alloys.

Lead Screws vs Ball Screws: It's All about the Application

Each type of actuator has its advantages and disadvantages. Before you can decide on what type of screw to use, you need to understand how the distinct characteristics of each match your specific application.

What are the advantages/disadvantages of lead screws?

Lead screws cost less.

Lead screws are self-locking and do not require a braking system.

Lead screws are better for vertical applications.

Lead screws are generally less efficient, requiring greater torque and a larger motor and drive.

Lead screws have higher friction and run a hotter temperature.

Most lead screws are not well suited to high throughput, high speed applications or those with continuous or long cycle times.

Lead screws need to be replaced more frequently.
