Machine Screws

The term ‘machine screws’ covers a broad range of fastener varieties that feature a head socket allowing screwdrivers to turn quickly and are widely used products among other standard fastener types. These screws are equipped with a blunt steel or brass end and are commonly used on a great range of electronic devices, machinery, and vehicles to join two or more metal parts or objects together. Furthermore, machine screws (often abbreviated as MS) come in either coarse-threaded or fine-threaded form with various ranges of head types. However, MS is fully threaded, which means they are directly driven into the thread, making it more beneficial because it results in stronger joints; ultimately, the quality of the product is higher.

Why Buy Machine Screws?

These fasteners are usually favoured among several professionals and users and are distinguished from other common fastener types by their physical features, including: 

  • Their smaller and flat-tipped design both in length and diameter for tapering to a sharp point. 
  • Fully threaded with secure joints.
  • Extremely potent, allowing thread uniformity, quality, and precision.
  • Generally used with a pre-drilled tapped hole or a nut. 
  • Easy to apply and remove with robust resistance properties.
  • Applicable over various surfaces.

Materials for Machine Screws:

As machine screws are required for highly vibrational environments, bespoke screws must withstand vibration, where materials are the key to achieving the target. Low-quality materials could lead to screw failure and cracking during applications. Furthermore, the screws could also be exposed to environments with high moisture, so it is crucial to select the best materials for the screw and include the following:

  • Stainless Steel
  • Steel
  • Aluminium
  • Plastic
  • Silicone Bronze
  • Brass
  • Chrome, and
  • Alloy Steel. 

Types of Machine Screws: 

They are categorized based on their head shapes and drive types, briefly discussed below. 

  • Machine Screws’ Head Shapes - The most popular head types are countersunk or Cheesehead, although there are other types around, including Cheese, Countersunk, Truss, Pan, and Flat.
  • Drive Types - A machine screw drive type refers to the device type required to remove, insert/install the screw. There is a vast array of drive types, including slotted, Hex, and Cross.

Typical Applications of Machine Screws:

As the name indicates, machine screws are designed to fix various parts and panels together in various environments. These are crucial tools for manufacturing, industry, construction, assembly processes, and other production settings. Other applications include:

  • Consumer Applications
  • Electronic and Electrical Components
  • Industrial Equipment
  • Automotive Applications
  • Machinery Equipment
  • Drilling Applications for Machinery
  • Construction and Production Applications
  • Other tasks like Terminal strips, sandwich gaskets, and membranes.

RS PRO BZP Plated Steel Pan Head Pozidriv Machine Screws From RS PRO a high-quality pan head machine screw with a versatile Pozidriv recess for a superior grip when tightening. This machine screw has a metric thread and is made from high-quality BZP (Bright Zinc Plated) steel which slows down rusting and corrosion What is a Machine Screw? A machine screw is similar to a bolt but has a socket or a slot in its head that allows it to be turned by a screwdriver. The shank on a machine screw is straight rather than tapered with a full thread which is uniform along the entire length. Machine screws do not tap their own thread into materials like wood screws do but are designed to be fastened into pre-tapped holes in the parts they are fastening together. Having a threaded hole creates a stronger joint and results in a higher quality product. What is a Pan Head Screw? Pan head machine screws, as the name suggests, have a head that looks like an inverted frying pan. The heads are flat on the top and rounded on the sides. When driven into material pan head machine screws protrude rather than sit flush. These screw head types are used when a flat bearing surface is needed but a countersunk screw is not required. What is a Pozidriv Head Type? Pozidriv, sometimes shortened to Pozi, stands for “positive drive”. This head type has a cross recess in the centre with four small indentations around it creating 8 points of contact. This design provides improved engagement and contact with the screwdriver and prevents ejection force when tightening or loosening the machine screw. What is Bright Zinc Plating? BZP is a shiny coating is applied to the steel, this process prevents corrosion and rusting. If the application is situated within a harsh environment, BZP will provide much-needed longevity and reliability. Although it may not be as effective as stainless steel, the added benefit would be the price. As stainless steel is completely rustproof but expensive, BZP Steel offers a g...
