Screw clamps use screws to hold objects together, with different styles for different purposes. C-clamps and hose clamps are common types. The screw’s design allows for easy turning and tight holding through friction, but high vibration can cause loosening. A screw clamp is a type of fastener that uses a screw as the primary method […]
Auger feeders accurately measure or feed bulk materials using the auger principle. They can handle coarse-grained bulk or thick slurry materials and are controlled by servo motors for precise stop-start and speed control. There are two basic types: volumetric and gravimetric. An auger feeder is a device used in various industries to accurately measure or […]
Auger feeders accurately measure and transport coarse-grained bulk or thick slurry materials using a helical screw mounted on a central shaft. They are controlled by servo motors and come in two types: volumetric and gravimetric. They are commonly used in industries requiring constant and accurate control of feed rates. An auger feeder is a device […]
A screw actuator converts rotary motion into linear output motion by transferring the rotation of a motor to a threaded rod with a coarse screw-type thread. Lead screws are commonly used for this purpose and are machined to tighter tolerances for smoother output action. The screw actuator is efficient and cost-effective but has limited torque […]
A pocket screw jig is a tool used to drill pocket holes for butt joints in woodworking. It is affordable and saves time. Pocket holes are drilled at a sharp angle towards the end of the workpiece and are usually drilled in pairs. Commercially purchased jigs are made of metal and come with instructions. Some […]
An eye screw is a curved screw with a ring on one end used for hanging light to medium weight items. It can be made of stainless steel or brass and can be used in machinery with a shoulder and collar attached. An eye screw, also known as an eyelet or eyebolt, is a special […]
A screw conveyor uses a spiral inclined plane to move material and can be used in agriculture and industry. Flexible screw conveyors allow movement in any direction and can be used around obstacles. The device has been used since at least 235 BC for irrigation and in diverse applications such as pumps in wastewater treatment […]
The Edison screw is a popular light bulb fitting with a male screw pattern on one end and a female screw socket in the socket. It can be manufactured in various sizes, denoted by the letter E followed by the diameter of the base in millimeters. The most common household light bulb in the US […]
A bleed screw is a specialized screw that allows pressure to be relieved from a closed system, such as steam radiators or automobile brakes. It requires a specialized tool to open and can become contaminated over time. Bleeding can be difficult and replacement screws are available if needed. A bleed screw is a screw that […]
A screw compressor uses two screws to force air into a sealed chamber, with two types available: dry screw compressors and oil immersed units. Dry compressors use timing gears to maintain compression, while oil immersed units use lubricating oil to create a hydraulic seal and provide compression. These compressors are commonly used in industrial and […]
Self-tapping screws are used in construction and manufacturing. They come in different head designs and are used for sheet metal, wood, and steel applications. They drill through objects and create a tight bond with the material. Flat head self-tapping wood screws are best for deck construction. There are many types of screws used in construction […]
A screw terminal connects conductors using multi-twist fasteners and is used in electrical equipment. It requires crimp-type lugs for bare wire and can be mounted on equipment frames or circuit boards. It provides flexibility and accessibility in modular wiring design, and lock washers are needed for mobile transport. A wire nut is a replacement for […]
A lead screw converts rotary motion to linear motion by passing a threaded rod through a corresponding opposing thread cut into a moving piece. The thread is coarser and has a square profile to reduce friction. Examples include bench vices and car jacks. A lead screw, or feed screw as it is also known, is […]
Jacks are used to lift vehicles or objects off the ground. They come in scissor and worm screw designs, made of steel or light stainless steel. Scissor jacks are simple and portable, while worm screw jacks offer greater accuracy and can lift heavier loads. A jack is a device used to fully or partially lift […]
Screw bolts are fasteners used to securely connect objects, with a cylindrical shaft and external thread that advances during rotation. They are used with nuts and come in various materials and sizes. The type chosen depends on the application’s stresses and environment. A screw bolt is a type of fastener used to make mechanical connections […]
A screw extractor is a tool used to remove broken or damaged screws, bits, and bolts. It is available in different sizes and consists of very hard metal. Users begin by drilling a pilot hole in the top of the broken screw using a standard drill bit. The screw extractor must be mounted on a […]
Screw anchors are used to provide a secure grip for screws in thin, light, or brittle surfaces. They prevent screws from coming out and can be applied from the outside of a surface. Expansion anchors provide pressure and prevent sliding. Self-drilling anchors can be screwed directly into walls. Users must drill appropriate holes for other […]
Anodized screws are metal fasteners with enhanced oxidation for color coding, wear and corrosion resistance. Aluminum is the most common type due to its natural resistance to corrosion. Anodized screws are used in structures exposed to natural weather conditions and in high-stress metal parts. The surface coating is an oxide of the base metal, making […]
Screw joints are used in mechanical engineering for mounting metal bars or corners. They can be used with various materials and are often seen in pre-assembled furniture and plumbing fixtures. Ball screw joints are used in manufacturing equipment, while machine-screw joints are designed for wood. Screw joints are also used for assembling metal posts and […]
Drywall screws are used to attach gypsum sheets to framing members in walls and ceilings. They have countersunk heads that create a smooth finish and are available in two types for wood or steel framing. They are self-tapping and have a black phosphate coating to minimize rust. Drywall is a type of building material made […]
