- Round Slot Machine Screw can be used to fasten components together by means of through holes and securing with a nut at the other end or they are screwed into a tapped hole with the matching thread
- Machine screws are fully threaded and have uniformly threads, meaning they maintain the exact same diameter throughout the entire length of the threaded section of the fastener, unlike self tapping or chipboard screws which have tapered threads. As the name suggests, these screws can be used to fasten components in machines, tools, appliances and electronic devices. They are one of the most popular fasteners we sell
- Also known as: Metal Thread, Stove Bolt, Pan Head, Dome Head, Snap head
- Material / Coating: Brass fasteners are used for their physical and aesthetic properties. Brass is utilised due to its high thermal conductivity and corrosion resistant properties. It is suitable for use in hot and cold environments, and resistant to water corrosion, making it a staple of industries such as heating and plumbing
- Thread Pitch (Imperial):TPI stands for “threads per inch” which literally means the number of threads within each inch on a screw, a bolt, or a fastener. To determine the TPI of a screw, you simply count the number of threads contained within an inch of length. If the screw is less than an inch count upto ½” and x by 2
- Fastener length: is generally measured from the point where the surface of the material will be when the fastener is installed to the end of the fastener. Thus, fasteners with heads that sit above the surface are measured from under the head to the end of the fastener, while fasteners that sit flush with the surface are measured from the top of the head to the end of the fastener
