- Mushroom Combination Phillips / Slot Machine Screws 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, Truss Head, Roofing Head, Roofing Bolt, Gutter Bolt
- Material / Coating: Zinc Plated is the most common fastener of plating due to its the low cost and shinny bright silver finish. A thin layer of Zinc is applied by either electroplating or mechanically. It is intended to be used internally, whilst some people use it externally it isnt recommended if corrosion may be a concern, instead search our Stainless steel range
- 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
