11 Strange Screws You Don't See Every Day

2018-06-29
hey guys how are you doing and welcome to latest tech we don't want our channel to be just about the latest gadgets in new technology but to show you some interesting things about everyday objects or facts and things you might have never heard before like screws for example screws are everywhere right they hold your life and furniture together screws come in all different shapes and sizes but chances are you're probably only familiar with a few of them there's Phillips and flathead and if you're from Canada there is square Robertson story as well but that is only the tip of the screwy iceberg here's a brief tour of some of the screws you might have never heard before trust me you'll be surprised eleven strange screws you don't see every day number one more torque the more turrets screw was built by the Phillips screw company and there's a resemblance between it and the company's signature screw the main advantage the more torque screw offers is as the name implies more torque specifically the wide wings of the screw make for thicker and stronger drill bits and the increased contact area means more forces applied to screw essentially this is a heavy-duty Phillips screw commonly used in automotive and aerospace work number two pentalobe you may have some pentalobe screws lying around if you own an Apple device pentalobe screws were first implemented by Apple in 2009 on its MacBook Pro battery cases since then they've been implemented externally on several MacBook models and in every iPhone since the iPhone port the primary purpose of pentalobe screws is essentially just to be obscure so you won't automatically have the right screwdriver to fit them it's a moves to curb tampering and fiddling with apples characteristically closed devices although now that Apple puts them on everything pentalobe screw drivers are pretty easy to find number three one wastrels one way screws come in all kinds of different shapes but they're all used for the same purpose turning one way and only typically these crews are designed to fit slotted screwdrivers and feature a gentle slope in one direction that provides you a torque they're commonly found in public restrooms and other places where people shouldn't be on screen things numbered four blocks the lock screw has the shape of four overlapping squares the idea behind this type of store is to increase the number of contact points which increases torque and decreases where lock screws have 12 contact points one for each side many more than the four contact points on Philips or Robertson screws this makes lock screws well suited to high torque applications in industry number five Frierson at first glance this looks like a typical Philips screw however there are many important differences the fearsome shake is a perfect cross unlike the rounded Phillips cross giving the fierson screw higher torque and preventing the bit from slipping out or stripping the screw further the walls of the screw drive are designed so that a single screw driver can fit every size present screw basically Friesen is like a better designed Philips number six pause a drive posit drive is another screw designed by the Phillips screw company like the more torque screw the posit drive is designed to provide a greater contact surface for more force and less slipping one of the biggest downsides to deposit drive is that it looks too much like a Phillips and people often use a Phillips screwdriver an apposite right v or vice versa the best way to tell the difference between them is that a positive screw will have a small shallow secondary cross in between the main cross number seven torques torque screws were invented in 1967 as an alternative to the already popular Phillips screw Torx drives feature six or sometimes five lobes and this greater number of lobes increases the contact surface considerably as a result dark screws can be a grainy torque and slip out less easily than Phillips screws torque screws are used in all manner of applications primarily in automotive and electronics industries number eight torque said Torx head screws are designed by the Phillips screw company for sensitive aerospace applications the goal is to create an extremely high torque screw every part of the screw design from the straight walls to the offset cross is intended to provide the greatest possible torque number nine da t p3 da and T p3 are two different types of screw drive but they look fairly similar they're triangular drives which is fairly unique the ta has straight walls while the t p3 has walls that curve you'll often find these screws in the toys in your happy meal and the TA is also used in a bunch of low security applications like elevators or camping stones it's not hard to find a screwdriver that will fit it but it's not super easy either which is just enough security to keep people from opening up the stove and accidentally making it explode number 10 tri wing the tri wing screw is another Apple screw it was used in a few MacBook Pros back in 2010 and 2011 and it's also holding stuff together in the new iPhone 7 and 7 plus this one isn't proprietary though and it can be found in products made by Microsoft Nokia Nintendo and others in the past the try way was mostly used in aerospace and can be found in some old aircraft made by Lockheed and McDonnell Douglas number 11 key Rex kirik screws are used in high-security applications like ballot boxes and bank vaults key Rex screws are custom made with a unique shape but will only work with the corresponding unique screw driver essentially key Rex screws are unique keys deliberately created to be impossible to unscrew for anyone without the cars ball in dry hit that like button if you
