Screws

crews are essential fasteners used in various applications, such as woodworking, construction, and manufacturing. The anatomy of a screw includes the following parts:

1. Head: The head is the top part of the screw that is used to turn and tighten it. The shape of the head determines the type of driver required to turn it, such as a Phillips, slotted, or hexagonal driver.

2. Shank: The shank is the threaded portion of the screw that goes into the material being fastened. The shank may be partially or fully threaded, depending on the application.

3. Thread: The thread is the spiral ridge that runs along the shank and is used to grip the material being fastened. The thread pitch determines how far the screw will advance into the material with each turn.

4. Point: The point is the sharp end of the screw that is used to pierce and start the hole in the material being fastened. The point may be sharp, blunt, or self-tapping, depending on the application.

5. Thread Depth: The thread depth is the distance between the crest and the root of the thread. It determines how tightly the screw will grip the material being fastened.

6. Major Diameter: The major diameter is the largest diameter of the screw thread. It determines the size of the hole required for the screw to be threaded into the material.

7. Minor Diameter: The minor diameter is the smallest diameter of the screw thread. It determines the size of the root of the thread and the thickness of the screw shank.
   

   There are many different types of screw head designs, each with its own benefits

The DIN standards are recognized worldwide and used extensively in many industries, including engineering, manufacturing, and construction. In this article, we will discuss some of the DIN standards related to  machine screws, namely DIN 84, DIN 7985, DIN 85, DIN 963, DIN 965, DIN 964, and DIN 966.

DIN 84: This standard specifies the dimensions and tolerances of cheese head screws. Cheese head screws have a cylindrical head with a flat top and a flat bottom. The head has a larger diameter than the shank, which allows for a larger contact area with the surface being fastened. The screw has a straight slot for a screwdriver or a cross recessed slot. The dimensions specified in the standard include the diameter, length, head diameter, head height, and thread length. The tolerances ensure that the screws can fit into a corresponding nut or threaded hole.

DIN 7985: This standard specifies the dimensions and tolerances of pan head screws. Pan head screws have a rounded, dome-shaped head with a flat bearing surface. The head has a smaller diameter than the shank, which allows for a smaller contact area with the surface being fastened. The screw has a cross recessed slot or a hexagonal socket. The dimensions specified in the standard include the diameter, length, head diameter, head height, and thread length. The tolerances ensure that the screws can fit into a corresponding nut or threaded hole.

Socket head screws are a type of fastener that have a cylindrical head with a hexagonal depression or socket on the top. This socket allows for easy tightening and loosening of the screw using a hex wrench or Allen key. Socket head screws are commonly used in a variety of applications, including machinery, electronics, and automotive industries. They are popular because they offer several advantages over other types of screws:

1. High torque: The socket head allows for greater torque to be applied to the screw, which makes them ideal for applications where high strength and reliability are required.

2. Low profile: The low profile head of the socket head screw allows it to sit flush with the surface of the material being fastened, which can be important in applications where space is limited.

3. Easy to use: The hexagonal socket on the top of the screw head makes it easy to tighten and loosen the screw, even in hard-to-reach areas.

4. Secure fastening: The hexagonal socket provides a secure grip on the screw, which reduces the risk of stripping or slipping during installation.

Socket head screws come in a variety of materials, including stainless steel, carbon steel, and alloy steel. They can also be coated or plated with various materials such as zinc, black oxide, and nickel for additional protection against corrosion and wear.

Socket heads come in various types, materials, and finishes. Here are some common types:

1. Hex Socket Head: A hex socket head has a six-sided shape and is designed

Self-tapping screws are a type of screw that can create threads in a material as they are driven into it. They are designed to create their own thread as they are turned, eliminating the need for a separate tapping tool or pre-made threads in the material. This makes them a popular choice for a wide range of applications, including woodworking, metalworking, and plastics.

In this blog, we'll explore the different types of self-tapping screws and their uses.

Types of Self-Tapping Screws

1. Sheet Metal Screws

Sheet metal screws are one of the most common types of self-tapping screws. They are used to attach two or more thin metal sheets together, and they come in a variety of sizes and shapes. Sheet metal screws typically have a pointed end and a flat, tapered head that can be driven flush with the surface of the material. They can be made of a variety of materials, including stainless steel, brass, and zinc-plated steel.

2. Wood Screws

Wood screws are self-tapping screws that are designed to be used with wood. They typically have a sharp point and a tapered shaft that allows them to be driven into wood without splitting it. Wood screws are available in a variety of sizes and lengths, and they can be made of different materials, including brass, stainless steel, and black oxide-coated steel.

3. Concrete Screws

Concrete screws are designed to be used with concrete, brick, or other masonry materials. They have a special thread design that allows them to grip the material securely, and they typically have a flat, tapered head that can be driven flush with
