Machine Screws :
Machine screws are a type of threaded fastener designed to be used with a tapped hole or with a nut to fasten two or more parts together. Unlike wood screws, which have a tapered point for use in wood, machine screws have a uniform diameter along their entire length and are intended for use in metal or other rigid materials.
Here are some key characteristics and features of machine screws:
Thread Type: Machine screws typically have a finer thread pitch compared to wood screws. The threading is designed for engagement with a corresponding threaded hole or a nut.
Head Types: Machine screws come with various head types, including:
- Pan Head: Flat on top with a rounded outer edge.
- Round Head: Circular head, often with a domed top.
- Truss Head: A wide, rounded head with a low profile.
- Hex Head: A head with a hexagonal shape, requiring a wrench or socket for tightening.
Drive Types: The head of machine screws can have different drive types, such as Phillips, slotted, hex, or Torx, among others.
Applications: Machine screws are used in various applications, including assembling machinery, electronics, appliances, and other devices. They are commonly used in conjunction with nuts or threaded holes.
Sizes: Machine screws come in a range of sizes, with variations in length and diameter. The sizing is typically specified using a combination of a diameter number and a thread pitch number (e.g., #6-32, where #6 is the diameter and 32 is the number of threads per inch).
When selecting machine screws for a particular application, factors such as material compatibility, size, head type, and drive type should be considered. It's essential to choose the right screw for the specific requirements of the project to ensure proper fastening and overall structural integrity.
Machine Screws : Machine screws are a common, yet specific subcategory of screws that feature small diameter uniform thread and a flat shank end. They are typically used in pre-drilled holes, which provides extra holding strength. While they function the same as other screws, their small size/strength ratio makes them versatile for a wide range of applications.
- Round head and pan head machine screws feature slightly different dome-shaped heads for which work well in low-speed environments
- Flat head machine screws feature a countersunk head that lies flush with the mating surface
- Binder head machine screws are similar to pan heads but feature a deeper slot
- Hex head machine screws are used in high torque applications and do not strip as easily as other head types
