Design and Uses of Slotted Fillister Metric Machine Screws

Slotted fillister metric machine screws are known for their tensile strength, durability, resistance to corrosion, incredible toughness, and excellent application performance. The screws are popular due to their unique design and varied uses.

Slotted Fillister Metric Machine Screw Design

The basic design of the screw makes it different from other screw types. Slotted fillister metric machine screws are known for their large diameter heads, long body lengths, and coarse threading. The fillister head has a helical ridge, which is designed to provide high torque as well as immense strength in an application.

Formability, high strength, durability, carrions resistance, and cost???effectiveness are important aspects that are considered when choosing slotted fillister metric machine screws. Stainless steel is always the preferred material for manufacturing the screw as it meets all the aforementioned qualities. However, a number of fastener manufacturers also design the screw using other materials such as:

  • Nylon 6/6 PCTFE
  • Carbon filled PEEK
  • Torlon
  • ABS

Slotted fillister machine screws are seen by many in the industry as a good replacement for round head fasteners. The large head size and deep drive slot allows for high torque levels to be generated. Although power drivers are not suitable with this screw, one can use a flat-bladed driver, which will provide effective screw installation. One should look at the external diameter, the thread pitch, and coarseness of the threading before using the screw in an application.

These screws are generally used along with nuts and are driven into tapped holes. For this reason, slotted fillister machine screws are also known as machine bolts. They are often used in old applications when a strong screw is required to replace an old or damaged screw. Slotted fillister machine screws are extensively used in the electrical and heavy machinery industry. Another common industrial application is woodworking.
