Your fastener distributor carries a wide range of machine screws, ideal for many different applications. These blunt-ended screws can be installed in tapped holes and used with a matching nut. Although a machine screw can also be labeled as a bolt, the small sizes are more recognizable as a screw. |
Different styles of machine screw heads suit different purposes. Take a closer look at these head types to choose the ideal type for your application.
Slotted Round and Phillip Round Machine Screw
A round head machine screw is formed with a domed head, which is close to or exactly half of a sphere. This smooth head provides an attractive finish, and comes in both slotted and Phillip drives.
A slotted round machine screw requires the use of a slot or flat screwdriver or bit. It can be loosened and tightened easily, even in hidden or blind locations. A Phillip round machine screw is shaped like an "x," making it more difficult to strip the screw head. It may require a certain size of Phillips screwdriver, depending on the diameter of the machine screw.
Phillip Flat and Slotted Flat Machine Screw
Flat head machine screws are countersunk into the tapped hole, providing a flush finish. The head is coned shaped to allow for this, and fairly thin in comparison to round head types.
Flat head machine screws are also available in slotted styles and Phillip heads. A slotted flat machine screw provides a simple solution in any application, while the Phillip flat machine screw remains one of the most popular types on the market.
Slotted Pan and Phillip Pan Machine Screw
Pan head machine screws look similar to round head types, with a less pronounced dome and shorter sides. A slotted pan machine screw uses the slot-style head, although it provides less depth of head than the round style.
Your fastener distributor sells a substantial amount of Phillip pan machine screws every season. It provides the same benefits as the Phillip flat head machine screw, without the flush finish.
Phillip Oval and Slotted Oval Machine Screw
On oval headed machine screw is countersunk without a completely flush finish. The head is a slight dome with a cone underneath. Offering an attractive finish in both slotted and Phillips drives, this type of machine screw works well for many applications in wood, metal and many other materials.
Various metals are used for a Phillip oval machine screw and a slotted oval machine screw, including stainless steel, zinc plated steel, plain finish and brass. The ideal material depends on your application.
Phillip Truss Machine Screw
A Phillip truss machine screw provides a wider head than other styles. The low profile of this fastener makes it ideal for machinery, where obstructions may create a problem. This type of low profile machine screw is tightened with a Phillips screwdriver, making it more difficult to strip.
Slotted Hex Machine Screw
A slotted hex machine screw comes with various tips, including a blunt end and a thread cutting or self-tapping tip. Because the head is formed with six flat sides, creating a hex shape, it can be tightened and loosened with a common wrench.
This fastener may or may not have a washer attached washer, and the slotted hex machine screw can also be installed with a flat-headed or slot screwdriver.
Your fastener distributor offers a broad selection of machine screws, including all of the common types listed above. Talk to an industry professional about which type is best for your application, and consider the ideal length and material.
