threaded hole strength in 6061 aluminum

7075 aluminum thread pull-out force question Engineers

Determine the yield strength of you weakest part (the aluminum). Then, yield stress = [load maximum]/ (thread stress area * number of threads of engagement) or, load maximum = [yield stress] * [thread stress area * number of threads of engagement) Modified by Cragyon at Wed, Mar 03, 2004, 10:46:03.

It appears to have a Rockwell B hardness of about 60 and a tensile strength of about 47,000 psi. This may be harder than a low cost low strength hardware store zinc plated screw, right?

STRIPPING STRENGTH OF TAPPED HOLES

n Tapped holes had a basic thread depth within the range of 65 to 80 per cent. Threads of tapped holes were Class 2B fit or better. n Minimum amount of metal surrounding the tapped hole was 2 1/2 times the major diameter. n Test loads were applied slowly in tension to screws having standard Class 3A threads. (Data, though, will Tech Q&A taken from Aluminum Now MagazineJun 01, 2011 · strength is 22.0 ksi. For 6061-T6, the minimum yield strength is 35.0 ksi and the minimum ultimate tensile strength is 38.0 ksi. For windows, 6063 is often chosen. Sometimes 6061 would be chosen because of its higher strength, but it would probably not be chosen if the intent is to anodize because 6061 doesnt anodize as well as 6063.

Thread forming vs tapping in aluminum. The Hobby

Apr 04, 2014 · I cannot speak to the use of form taps in plastic, but I have form tapped literally thousands of holes in both 6061 and 2024 alloys. Overall, the thread produced is superior to a cut tap thread. It is smoother, stronger, has no chips to worry about. There are two downsides that I will mention. Threaded hole strength in 6061 - Practical MachinistApr 09, 2014 · Threaded hole strength in 6061. I need to determine the tensile strength for a standard steel M3 socket screw that is threaded into a 6061 aluminum part. Alu threads will be tap-cut. Thread depth is 4.5mm, but I'd say allow .5mm for chamfer, etc., call it 4mm of engagement. I can't make the hole any deeper.

I need to determine how much load this can handle. Parameters and constraints:- Standard steel M3 socket screw. - Threaded hole into a 6061 aluminum part.
