What are Tek screws good for?
Tek screws, also called self-drilling screws, are self-tapping fasteners that have a drill bit end allowing them to be used for screwing materials such as wood and metal together without pre-drilling. Tek screws are best fitted with a high-speed impact drive.
Do Tek screws need a pilot hole?
Each Tek screw features a carving piece on its tip, which is what makes self-drilling possible. This means you don’t need to create a pilot hole before the fastener, and it also means your work moves forward efficiently. Plus, Tek screws are versatile.
What size do Tek screws come in?
TEK® screws are available in a variety of shank lengths and diameters. Diameter is indicated by a numeric size that runs from #6 to #14, with #6 being the thinnest and #14 being the thickest. The #8 and #10 TEK® screws are the most commonly used.
When would you use a winged screw?
Point Wings are used on some screws that fasten thicker materials, such as wood, to metal. The wings enlarge the hole in the fastened material, allowing the threads to pass through without contacting the fastened material.
Can you reuse Tek screws?
Understanding types and materials of which they are applied is vital – for example if you are using self-tapping screws for aluminium, they don’t need pre-drilling and are easily removed without any damage caused to the metal. And, actually, they can be reused in the same material.
What drill do you use for TEK screws?
Power drills with adjustable clutch settings are better suited for use with Tek screws on light sheet metal than Impact drills. The hammering action generated by impact drills can cause metal dimpling or oil canning deformations on lightweight metal sheets.
How much can a tek screw hold?
Larger Tek screws (No. 3 Tek and above) are strong enough to penetrate 12~20-gauge galvanized steel, as well as 3/8” to ½” (10~12.5 mm) structural steel and can be used on various civil and naval engineering applications.
How much weight will a tek screw hold?
around 80 to 100 pounds
Typically, a self-tapping screw can sustain around 80 to 100 pounds of weight.
What do TEK screw numbers mean?
Self-drilling screws have drill bit tips which are numbered from #1 up to #5, indicating the length of the flute. The flute is the part of the Tek screw that determines the metal thickness the screw can drill into. That means the bigger the number, the thicker the metal it can go through without a pilot hole.
Do Tek screws rust?
Tek screws are made from high-grade, anti-corrosive material that can withstand rust and corrosion.
Why is it called a tek screw?
Tek is to self-drilling screws as Kleenex is to nose tissue – a brand name. As the first of its kind, “tek” became synonymous with the self-drilling screw design, and now tek screws are essential for a range of applications today.
Can Tek screws be used in steel?
What screws are best for masonry?
Masonry screws are manufactured from carbon steel that has a blue coating or from a 410 stainless steel which also has a protective coating. The standard blue coated masonry screw is for use in indoor applications where moisture is not present.
