design with tek screws
has anyone worked with tek screws. i need to know the diameter and propeties for those screws. if i am using #14 tek screws, how do i go around calculating the my required loads, the screw can bear. what does # in 14 means. i also needed to know the size / diameter for those screws.. check out our whitepaper library. look in a dietrich catalog. you can get shear and tension values for different gauge thicknesses. i believe it will also tell you the diameter. if dietrich doesn't have the diameter, i am pretty sure hilti does. i looked in hilti, but didnot come across the name tek screws , do they call it by different name and what does # in tek stand for... is it like rebars in steel.. # is just a reference to the diameter of the screw. i believe tek just means it is meant for metal to metal connection. teks is a brand name of the screw, manufactured by buildex. their website has everything you're looking for. nutte- i've found about 50 websites that sell "tek" screws. are they all just vendors for buildex? "teks" screw is universally used for self-tapping, self-drilling metal screws, just like "bandaid" is used for adhesive bandages. as nutte said, tek is the brand name for self drilling screws by itw buildex. when you say #14, it means nominal screw size. look at the itw buildex website. you will find all the info. i am not so sure. if you google tek screws, you get a lot of sites that sell them with no mention of buildex. maybe you guys are right, but it seems to be a more generic term for self-drilling, self-tapping metal screws like spats says. tek is a brand name for self-drilling self-tapping screws made by itw. hilti calls them kwik-pro. grabber calls them something else, as do other manufacturers. the term is often used generically, like saying "tapcons" for concrete screws or the band-aids reference above, but formally tek is a brand name. to design with them, you can refer to manufacturer-supplied data that is usually based on testing, but not necessarily. alternatively you can use your material standard. if these are for cold-formed steel connections you would use the naspec if you're in north america. it is you'll find different limit states to be checked with which you can arrive at a final design value for shear, tension, pull-out and pull-over. if you are not in north america, see if you have a similar standard to use. ssma catalog has screw shear and tension values for different sheet metal thicknesses. |
