Machine screws are threaded fasteners designed to securely join two or more parts together. They are typically made of metal, such as steel or stainless steel, and have a cylindrical shaft with threads along their entire length. Truss head machine screws are characterised by their low-profile head, making them suitable for applications with minimal clearance. The length of a truss head machine screw is measured from under the head to the end of the screw. They are available in various sizes, with #6-32 being one of the options.
Characteristics | Values |

Length | Measured from under the head to the end of the screw |
Thread | Uniformly threaded, designed to be fastened into tapped holes or used with nuts |
Applications | Fastening components of tools, appliances, machines, and electronic devices |
Driver | Phillips, Slotted, or Allen wrench |
Material | Steel, stainless steel, or zinc-plated steel |
Length measurement
The length of a 6 truss head machine screw is a key specification to consider when selecting the right fastener for your application. The length of this type of screw is measured from under its head to the tip of the screw.
Machine screws are designed to securely join two or more parts together and are typically made of metal, such as steel or stainless steel. They are commonly used in a wide range of industries, including manufacturing, construction, automotive, and electronics.
When selecting a 6 truss head machine screw, it is important to choose the appropriate length for your specific application. The length of the screw will determine how far it can reach into the material being fastened and how much of the screw will be exposed.
Truss head machine screws are characterised by their low-profile head, making them suitable for applications with minimal clearance. The length of the screw can vary depending on the specific requirements of the application, and they are available in various standard lengths.
When measuring the length of a 6 truss head machine screw, it is important to use a calibrated measuring tool, such as a ruler or caliper, to ensure accuracy. The length should be measured from the underside of the screw head to the tip of the screw, following the cylindrical shaft of the screw.

Materials
Machine screws are typically made of metal, such as steel or stainless steel. They are available in a variety of materials, including:
Steel
Steel machine screws are commonly used and provide high strength and durability. They are often zinc-plated to resist corrosion and improve their appearance. Zinc plating gives the screws a shiny, silvery finish and enhances their resistance to rust and oxidation.
Stainless Steel
Stainless steel is another popular choice for machine screws. It offers excellent corrosion resistance, making it suitable for applications where the screws will be exposed to moisture or harsh environments. Stainless steel has a sleek, modern appearance and is known for its strength and durability.
Other Materials
Although less common, machine screws can also be made from other materials, such as brass, nylon, or even exotic alloys, depending on the specific application and requirements. Brass machine screws offer good corrosion resistance and electrical conductivity, while nylon machine screws are lightweight and non-conductive, ideal for applications where insulation is important.
In addition to the material, the finish of the screw can also vary. Different finishes can provide additional protection or be used for decorative purposes. For example, some screws may have a chrome or nickel plating, which can enhance corrosion resistance and improve the overall appearance of the screw.

Typical applications
Machine screws are threaded fasteners designed to securely join two or more parts together. They are typically made of metal, such as steel or stainless steel, and have a cylindrical shaft with threads along their entire length.
The typical applications of a 6 truss head machine screw include fastening components of tools, appliances, machines, and electronic devices. They are ideal for applications with minimal clearance due to their low-profile head. The 6 truss head machine screw can be used in conjunction with nuts or tapped holes to join two or more assemblies together.
The 6 truss head machine screw is just one of many types of machine screws available, each with its own unique features and applications. For example, the Binding Undercut type is ideal for electrical connections due to its flat bearing surface and annular undercut, while the Button type features a domed top that protrudes above the fastening surface. The Fillister, or Cheese, type is commonly used in counterbored holes due to its rounded top and cylindrical sides.
The 6 truss head machine screw is suitable for a wide range of industries, including manufacturing, construction, automotive, and electronics. They are available in various sizes, thread pitches, and head styles to meet different needs and applications.

Head styles
Machine screws are threaded fasteners designed to securely join two or more parts together. They are available in a variety of sizes, thread pitches, and head styles to suit different needs and applications.
The truss head is a low-profile head style suitable for applications with minimal clearance. The length of a truss head machine screw is measured from under the head to the end of the screw. Truss head machine screws are often used in conjunction with tapped holes and nuts. They have machine threads and can be used with a nut or in a tapped hole. They can also be referred to as stove bolts.
There are several other head styles available for machine screws, each with its own unique features and applications:
- Binding Undercut: This type has a flat bearing surface and an annular undercut, making it ideal for electrical connections.
- Button: Features a domed top that protrudes above the fastening surface.
- Fillister (or Cheese): This type has a rounded top and cylindrical sides, commonly used in counterbored holes.
- Flat: Countersunk head with a flat top, suitable for applications where protrusion is undesirable.
- Indented Hex: This style has an indented top and can transmit higher torque, making it preferred for high-volume assembly.
- Indented Hex Washer: Offers additional protection to the mating surface.
- Oval: Countersunk head with a rounded top, often used in conical applications or for decorative purposes.
- Pan: General-purpose head with a flat or gently rounded top.
- Round: This style has a semi-elliptical top surface and is preferred for its smooth appearance.
Each head style has its own size chart and specifications, which can be found on fastener supplier websites.

Drive types
Machine screws are available in a variety of drive types, each requiring a different type of tool for installation or removal. The most common drive types are slotted, Phillips, combination (both slotted and Phillips), hex, hex socket, square, Torx® and spanner.
Slotted
Slotted drive types, also known as traditional drive styles, require a flat-blade screwdriver. Slotted screws are often used in conjunction with a nut or in a tapped hole.
Phillips
Phillips drive types are the most common and provide good control. They require a Phillips screwdriver and are often used for finish work.
Combination
Combination drive types feature both a slotted and Phillips drive, allowing them to be tightened or loosened with either a flat-blade or Phillips screwdriver.
Hex
Hex drive types, also known as hex cap screws, require a wrench or socket for installation or removal.
Hex Socket
Hex socket drive types require a hex key, also known as an Allen wrench, for tightening or loosening.
Square
Square drive types require a wrench for installation or removal. They offer a degree of security as the required tool is not as common.
Torx®
Torx® drive types, also known as six-lobe or star drive, have six points of contact, allowing for more torque to be applied without stripping the recess. They require a Torx® driver and are considered more secure than other drive types.
Spanner
Spanner drive types require a special tool and are designed for security applications.
When selecting a drive type, it is important to match the driver to the screw head to prevent damage. Additionally, some drive types, such as Phillips, come in different sizes, so choosing the correct size driver is crucial.
