Screws have grooves along the shaft to create a secure bond with materials. The screw thread can differentiate screw types and determine where to use them. Screw size and pitch are important characteristics to consider. Screw thread sizes are measured using UTS in the US and ISO worldwide. A screw is a type of fastener […]
Machine screws are small screws designed to be fastened into an existing threaded hole in a metal surface with a matching nut. They come in different sizes, head shapes, groove types, lengths, materials, and thread characteristics. The type of slot in the head determines the type of screwdriver needed. The thread characteristics follow ISO standards, […]
The Allen screw, also known as a hex head screw, uses an Allen wrench to tighten and remove. It is a high-strength fastener made from various metals and is commonly used in machine building, high performance, and aircraft applications. The fine thread pitch holds tight without the need for lock washers or nuts, and the […]
Augers are used in industrial machinery to move materials through a pipe. They are commonly used in the plastics and food manufacturing industries to mix and extrude products. Augers can also be used to blend raw materials into a final product with precise amounts dispensed by each auger. An auger is a component of some […]
Hex head screws and hex bolts are often confused, but they have different characteristics. Hex screws are smaller, don’t always require a nut, and have a built-in washer. They are used in manufacturing and industrial applications where accuracy is important. Users should choose the right material and size for each project. A hex head screw […]
Lead screws allow limited movements in machines, such as rotation or up and down motion. They are used in various environments, including industrial machines and medical procedures. Screw guides are a replacement for drilling holes and help ensure precise screw insertion. They are available in sets with different diameters and can be purchased online or […]
Adjustment screws are used to make precise adjustments on various items, from embroidery hoops to heavy machinery. They can be reinforced and replaced if damaged. They allow for fine-tuning of spacing and tension and are found on many types of heavy machinery. Some are designed to lock, and it’s important to read the manual for […]
A lag screw is a strong, coarse-threaded screw with a hex head that requires a wrench to tighten or remove. It is used for maximum strength and clamping force in projects such as deck attachment or gate fitting. A pilot hole is necessary to avoid splitting the wood, and a flat washer can prevent the […]
A wood screw is used to join wood and has a hollow shank. It requires a pilot hole to prevent the wood from snapping. Drywall screws are not suitable for structural strength and have threads running the entire length. A wood screw is used to join two pieces of wood together. Made of steel, the […]
Set screws secure objects together, preventing movement and allowing them to function as intended. They are usually made of brass or stainless steel and have an internal mechanism for attachment. The pointed end can vary in shape, with cupped and flat tips being the most common. Set screws are used in a variety of applications, […]
Sheet metal screws are used to fasten metal objects and have a threaded shank with a sharp tip. They are labeled with three numbers indicating diameter, threads, and length. There are two types: standard drives and self-tapping. The head can be button, pan, flat, or oval, with different slots. They can be made from carbon […]
A set screw is a type of fastener with a head no larger than the body, often with a recessed drive port. They are used in mechanical systems where metal surfaces rub against each other and where recessed screws are needed for aesthetic or safety reasons. Advantages include resistance to corrosion and the ability to […]
Cap screws are fasteners used to secure machine parts and other objects. They have a large head and a cylindrical shaft with an external thread that matches the internal thread of a tapped hole. Cap screws come in different sizes, types, and materials, and generate high clamping force when tightened. They can be made of […]
Screw propellers consist of angled blades rotating around a hub to provide thrust in air or water. They work like a screw, pushing air or water to create thrust in the opposite direction. The earliest roots of the screw propeller date back to the Archimedean screw, and several inventors in the early 19th century are […]
Screw couplers are used to join solid or hollow components with mating threads. They can be simple or complex, and are used in various applications such as construction and irrigation systems. They are easy to disconnect and can be made of different materials. A screw coupler is a device used to mechanically join two separate […]
Ball screws are a type of nut and bolt with a unique design consisting of many ball bearings within a sleeve. They provide smooth motion and are used in industries such as robotics and aeronautics. They are highly efficient but expensive and not suitable for all industries due to restrictions and the need for cleanliness. […]
Button head screws have a large head that distributes weight over a larger area, increasing strength. Different types of screws have different recesses and threads for different materials. Coarse threads are used for softer materials like wood, while fine threads are used for metal. Self-tapping screws are used for thin sheet metal. A button head […]
A screw conveyor is a device used to move small materials quickly and efficiently in industries such as food manufacturing and agriculture. It consists of a large screw contained within a tube or cylinder. The screw system is more appropriate for smaller materials and is fully enclosed, reducing the risk of materials falling out or […]
A threader shapes threads on screws or nuts, securing separate elements together using rotational force. Male threads are external, female threads are internal. Threads can be produced by hand or machined by lathes. Various tools create thread styles with attention to dimensions. A threader is a tool or piece of equipment that can shape threads […]
Plastic screws are lightweight, strong, and resistant to corrosion, making them ideal for use in consumer electronics and small appliances. They come in various materials and types, including pan head and hex head, and can generate significant clamping force when tightened. However, their strength is limited compared to steel, so they are not suitable for […]
