How do I thread a bolt?

Posts: 6 EDU
I'm new to Onshape. I'm a high school teacher who just started using this program. My students are designing toy trains. We need to do a bolt with specs of 1/4 - 20 UNC 1/2" OFFSET for the threads. I cannot find a tool to do this. Please help.

Many types of standard hardware are available to insert into an assembly. When in an assembly tab, just click Insert. Next, select the Standard Content tap.

They can if they add this to their toolbar, or they can model it by hand.

Is this an app we would have to buy?0

No, it only costs you 3 mouse clicks

That makes sense. If it's more about the exercise than the result (learning about threads, not just having them), then they'll have to:mary_morrison111 said:It's in the curriculum. I think it's there so the students are forced to understand what pitch is, and how to read the specifications. That's a very interesting point though and I will pass it along. Thank you and thank you for all your help today. Switching from teaching Autodesk Inventor in a school computer lab to teaching Onshape in distance learning overnight has been challenging. I truly appreciate the community of people, including you, who are supporting me.- make a cylinder with the correct diameter. (major dia for cutting threads or minor dia for adding them)
- make a helix on the cylinder with the correct pitch.
- sketch the thread profile
- sweep the profile.

Thank you. I assigned students to create their own bolt with threads. We could do that in Autodesk Inventor. I guess we can't here. I appreciate your help.0

I know this is an educational exercise, and I I'm probably being pedantic, but in general one shouldn't model threads unless absolutely necessary. You'd be surprised how often I see professional engineers bog down their models with threaded screws. The only time fully modeled threads are truly useful is if it's a larger thread that's being 3D printed, or if they are normally suppressed but were unsuppressed for a pretty picture. McMaster-Carr, I'm looking at you...
Just something to pass on to your students. Gotta start them young
