Machine Screws
Understanding the Versatility and Strength of Industrial Machine Screws
Machine screws are differentiated from other screws by two characteristics: 1) ASME dictates that their diameter must not exceed 3/4 in.; 2) they have a flat end and uniform threads. These differences do not diminish their versatility, as they are widely used in anything from machinery to electrical components to instruments. Their wide variety of head styles lends them to unique applications that require specific installation, surface profiles, extra grip, or aesthetic appeal.
Machine screws are used in conjunction with tapped holes or nuts, although the nuts are not always necessary. They are driven into a pre-drilled hole with a drill or screwdriver and often do not need more connection power (this depends on the application). Huyett offers them in over 10 different head types – including truss, round, pan, flat, button, oval, cheese, and more – with a wide variety of drive types to provide the right fastener for your connection needs.
- Material Variety: Huyett offers machine screws in multiple materials, including low carbon steel, stainless steel, brass, and silicone bronze, so you can choose the material that provides the performance you need.
- Corrosion Resistance: Finishes include black oxide and several zinc options to fortify the fastener with superior corrosion resistance.

Common Types of Machine Screw Heads and Their Applications
Pan Head Screws: Wide, circular head with a flat bearing surface; ideal for machinery and automotive parts.
Binder Head Screws: Thick heads with deep slots and indentations under the bearing side; used in electrical applications and binding material swatches.
Cheese Head Screws: Deep head and flat disc top; used in appliances, automotives, and fixtures.
Truss Head Screws: Slightly round, mushroom shape; work well in applications that do not require a flush finish.
Sidewalk Head Screws: Very low-profile that can be “walked on” without interference; works well in applications that require a flush finish.
