Nice video. Was looking into screwing a clam shell type of assembly together from something I am 3D printing. Just wanted to seat down a servo into some ABS, but hardly knew much about screws and their terminology.
Thanks for leaving a comment, Mike! We're glad you found the video helpful. If you're interested in 3D printing, we recommend you check out our 3D printing/additive manufacturing video if you haven't yet: ua-cam.com/video/z-N9V2s6LFk/v-deo.html
Since miniature screws have very fine threads, making it easier and easier to strip plastic, at what point are brass inserts required? An M6 screw I can definitely see not needing an insert, but what about M2 or M3? Those threads are much finer.
Hi, Jerry! Depending on the application requirements, brass inserts may not be necessary to prevent strip-out with screws down to 1mm in diameter. If a properly dimensioned screw boss, optimized installation torque, low drive speed, and the latest multi-angle thread designs are being used successfully, it can work even in very small sizes. Start with understanding the plastic material needed for the application, then design the joint to accomplish low material stress and optimum-not maximum-clamp load. If you have further questions on specifics, you can email me at wurthknowing@wurthindustry.com. - Randy Lammers
Just what I needed to know. Thumbs up!
Just outstanding! Thanx guys!!
Thanks Mark!
Excellent Job, Randy and Aaron! Great information on screw applications for plastics!
Thank you, Steve!
