Screws Getting Stripped

Yes. You are over-tightening the screws.

Wrong torque.

Wrong material.

What is the thread?

Are you screwing into plastic?

Many reasons that you should have already eliminated before coming here.

What have you done so far???

The video is useless and you give no useful information.

Insufficient data.

Hole size, depth, material
Screw size, material, type and pitch of threads
Is the hole tapped, or is the screw self-tapping?

Anonymous Poster #1,
Are you afraid your employer will find out you're totally out of your depth and having to ask on the internet?

Do your own job or find a new position.

I suspect there are multiple problems here. Clearly the attempted torque is higher than the material can handle, but this may not be the root of the problem.

The question should be why does the OP wishes to apply so much torque on these screws that they strip threads? The component(s) design could be at fault. The fabrication process could be inaccurate. While operator error can always be a problem, trying to find why things fail shows a desire to correct the problem.

Only problem I see is a lack of competence on the part of the person asking for an answer to an undefined problem.

They should turn the torque setting down.

First of all, I am a high school student so I am not an engineer yet. Me and my group are supposed to solve other problems (which we already did) but cannot figure this one out.

We will turn the torque setting down to see if it works.(Thanks for the suggestion)

Anyways,
Here is some of the information.
The screw is: 302 Stainless Steel, Passivated. M2-1.0 x 6.5mm ± 0.5mm

The hole is: 0.65in

The material is: DUPONT ZYTEL 70G13L

How did you come to the torque setting you are using?

Did you research the "screw pull-out torque" strength of Zytel?

Try

MatWeb: Online Materials Information Resource

or

Engineering ToolBox

ZYTEL 70G13L is a glass filled nylon 66 resin.

Does it look like this?

Finally, this is an engineering forum.

If you had made your second statement first, we'd have been more gentle, but this is the real world.

Why didn't your instructor give you a little help here?

Welcome.

How did you come to the torque setting you are using? It was given to us at that setting. At first when it started stripping I thought it was not calibrated. Guess I never questioned the torque setting but tomorrow I will change it and see what happens.

Yes, it looks like that.

Will take a look at those link you posted.

Good.

No, does your screw look like the first (correct) screw, which is for plastic?

The second screw is a machine screw and is for metal.

The first step to solving this problem is to change the things you can control, ONE AT A TIME, and note the results.

You will find that Google is invaluable in helping you find solutions.I start my searches with a simple question. Something like. "trouble shooting screw pull-out in plastics" That got me to Threaded Fasteners for Plastics - Stanley Engineered ...

Also, manufacturers have ton of data on their materials.

Like I said this is a Nylon and there are thousands of different types and formulations.Glass filling is common as it adds strength.

Here's a good source for DuPont.

Wait just one minute. A 0.65 in(ch) diameter hole is 16.51 millimeters in diameter. This is much bigger than the hole diameter of a M2 bolt, regardless of thread pitch. I know that you are a High School student and that this is probably just a typographic error but sound engineering requires getting the details right, clear and not ambiguous.

I suspect a major part of your problem here is switching between standards.

What type of screw are you using, thread forming or thread cutting? The forces involved in driving the screw depend upon the type of thread, the material it is being driven into, and the hole prep. (Sorry I couldn't view your video).

Thread forming screws deform the surrounding material, while thread cutting screws act similar to a tap in that they remove material which has to have some place to go. If it's a blind hole that isn't deep enough to accomodate the removed material then it will halt the forward progress of the screw and it will strip the threads it just cut.

Good for you.

Question everything.
