Zip Screws: What Makes a Stronger Zip Screw?
We, at All Points, believe that whether you call them Sheet Metal Screws, Self-Piercing, Self-Tapping or Speed Point, whether you are using them for HVAC, Gutter or Siding, one thing is certain, time is money and you can’t waste either. I’m sure there’s nothing more frustrating than balancing on a high pitched roof and having to deal with snapping, misaligned screws. Nothing worse than doing something twice.
Another problem you come across is bombarded with the overwhelming amount of screws to choose from. Well hopefully, we can shed a little light on some choices that are out there.
Here are some things to consider:
Hex Washer Heads: Our Hex Washer Head Screws are very popular in the industry. The Hex Head is desired because of its strength and stability. An important thing to consider is the height of the Hex Head. The higher the Hex Head, the more stable the screw. The drill chuck has a broader surface to use to reduce the tension placed on the head of the screw. Since the grip is more secure, there is a much lower chance of stripping the screw head. Which I’m sure you know the nightmare trying to remove a stripped screw head can be. In addition with a high performance hex head will help secure the chuck which will help stabilize the drilling and prevent “wobbling”.
Fillet: This feature strengthens the screw without increasing the size of the screw shaft.
Dacroment Salt Spray: This is a treatment that help to slow the natural oxidation of the metal. This is such a fantastic feature, especially since the forecasts are pointing to another icy, wet winter though out the entire U.S and a good part of Canada. (Credit to www.farmersalmanac.com)
Another fact to keep in mind is the type of screw you are looking for. Again, it will save time and money choose the right screw for the right job. For example, a #10 HWH Screw and a #8 HWH Screw will both work for Gutter Instillation, however, with the wood used in current construction projects have more knots than wood from twenty years ago. The #10 HWH has a thicker shaft and the threads are closer together, which slows the screw rotation. The slower rotation causes the screw to self-drill at a more controlled speed. This allows it to drill through knottier, denser wood, where as a #8 HWH has a thinner screw shaft and closer drill threads which increases the chance of snapping and stripping if used for the wrong application.
Our last suggestion to consider is the material the screw is made of. There are a few to choose from. First there is the Stainless Steel/Copper Plated Screw. This screw works really well with Copper Gutters. This screw is made with a 4/10 gauge steel allows this screw to be used with a magnetized drill chuck.
Another type of screw that works well with Metal Roofs, are Copper Screws. These screw more closely match the Copper Roof. They are made with a 18-8 gauge metal which means there is a higher percentage of copper. This means they are not magnetic, but they better match the natural patina of the copper roof over time.
Stainless Steel screw are another great option. Not only are they strong and durable, but they can be easily used with a magnetized drill chuck. They can be painted to match a lot of the popular colors of the newest styles of today’s metal roofs. Its durability is also a great option for the tiny house trends that becoming a creative option of mobile living.
Hopefully you have found this information informative and useful. With the trends of construction constantly changing, it’s hard to know what is out there. Good thing here at All Points, we are here to answer any questions you may have.
Tek Screws (Self-Drilling Screws) Review and Buying Guide
Self-drilling screws are not very new to the world of fasteners.
Because there are many names for the same part, it can end up being very confusing. They are not much different than standard screws but come with distinct features that make them standout clearly from the rest. They are of different types and each type has its specific role to play.
The following are some of the common types and how and when they are used:
- Bi-metal and stainless steel- tek screws made of this type of material is primarily used for fastening in situations where products made of stainless steel are required. Other situations it can be used include fitting steel to steel, stitching of casing panels as well as fixing composites or timber to aluminum.
- Type 17 point – Also known as an auger point can be used to join together profile metal sheets and timber purlins or cement sheets to light sections steel and timber.
- Heating & ventilation screws – 8×1/2 hex washer head self-tapping needlepoint and self-drilling screws are the most popular. is very simple; manufacture and assembly of air conditioning systems as well as ducting.
- Hex head for heavy steel – if you are out to fix steel to steel, this head style will be ideal for use as well as when fastening general components and liner panels to steel. They are also good for fixing roofing applications and cladding to both cold and hot rolled rails and purlins.
- Hex head for light steel – this head style is also good to fix steel to steel, fasten general components and liner panels to steel in addition to fixing roofing applications and cladding to both cold and hot rolled rails and purlins.
- Metal framing – these self-drilling screws are primarily used to fix any steel to steel even though there are many other options available. But, that is the main purpose of the screws.
- Stitching screws – as the name suggests, use these screws to stitch cladding panels.
- Reamer tek screw – if there are any composites and timber to fix to steel, these will be the ideal screws to use for accomplishing that. They are also good for fastening timber to thick steel sections including situations where normal tek screws cannot be used with very hard steels.
- Zinc coated – these are another type of screws to consider and are ideal for fastening in situations where you will not require high end corrosion resistant coating. Use them also when fixing composites and timber to steel.
- Composite panel fasteners – use these screws to fix roofing applications and cladding to both cold and hot rolled rails and purlins. Other applicable situations are when fastening general components and liner panels to very heavy steel.With all these types, the next big thing will be making out how to make the right purchase. You must be in a position of choosing the ideal screws to help accomplish the task you have at hand. If you are not well informed on how to go about your purchase process, it might end up in frustrations once you are stuck. Regardless of whether you are buying your screws from an online store or physical store, you must ensure everything is thorough.
Plan your purchase well
When you are looking for a quote, you should be ready to supply the following information:
- Head style-is it a hex head? If so, what size hex head will you be using? (1/4″, 5/16″, 3/8″)or do you need something to go flush? There are all types of head styles to fit the type of job.
What size shank will the screw need? The shank is the thickness of the screw. (#6, #8, #10, #12, #14). Keep in mind, the higher the number, the thicker the shank.
- How long is the screw? Very important. You would measure from underneath the head to the tip of the screw.
- What does the point look like? Is it sharp? Does it look like a drill bit? Does it have a groove at the end? Let the salesperson know what
you will be using it for and they can help you decide. Are you going through metal, wood?
- Will a zinc plated screw work for you? Or do you need stainless? copper? If it’s stainless, do you want magnetic, or non-magnetic?
- How many do you want and how quickly do you need them? Remember in the case of painted screws, there is a lead time for painting, so please get your quote early.
