	~~[[File:Square thread form~~.~~svg\|thumb\|200px\|Dimensions of a square thread form]]~~		Greetings! I am Bev. I have usually loved residing in Maine but I will have to transfer in a 12 months or two. I am a debt collector. To do inside design is the detail I enjoy most of all. I've been doing work on my web-site for some time now. Check out it out here: http://www.primaboinca.com/view_profile.php?userid=9687516<br><br>my homepage: [http://www.primaboinca.com/view_profile.php?userid=9687516 Nike air max hyperfuse blue]

	~~The '''square thread form''' is a common thread form for [[leadscrew]]s. It gets its name from the square cross-section of the thread.<ref name="bhandari203">Bhandari, p. 203.</ref>~~

	~~==Advantages & disadvantages==~~
	~~The greatest advantage of square threads is that they~~ have ~~a much higher intrinsic efficiency than [[Acme thread form\|Acme]] threads. Due~~ to ~~the lack of~~ a ~~[[thread angle]] there is no radial pressure,~~ or ~~[[bursting pressure]], on the nut~~. ~~This also increases the nut life~~.~~<ref name="bhandari203"/>~~

	~~The greatest disadvantage~~ is the ~~difficulty in machining such a thread~~. ~~The [[tool bit\|single~~-~~point cutting tools]] or [[tap and die\|taps and dies]] used to cut the thread cannot have efficient rake and relief angles (because of the square form), which makes the cutting slow and difficult~~. ~~Square threads also cannot carry as much load as a trapezoidal thread, because the root of the square thread is smaller. Also, there is no way to compensate for wear on the nut, so~~ it ~~must be replaced when worn~~ out~~.<ref name="bhandari203"/>~~

	~~==Classification==~~
