Hi, Lee - thank you for reaching out. When using the 1/4-20 or M6 t-nuts with the 10 and 25 series, the "coin" will instantly wedge into the t-slot and prevent removal or movement of the t-nut. The 5/16-18 and M8 t-nuts with the 15, 30, and 40 series will usually wedge into the t-slot when the 2 degree drop lock is engaged on the extrusion.
Hi there! While it does look like a tight fit, with a properly sized thread appropriate for the specific series of bracket and profile you're using, there should not be an issue with damaging the threads while using the Corner Brackets. You can search for your corner bracket on the website, which will provide you suggested hardware as well to ensure you have screws that can be used without damaging the threads: bit.ly/3NDIZLy
@@8020llc Thank you for the response. We are using a method which inserts the screw without damaging the threads although we were a little apprehensive at first to putting that much force on the screw. So far we love the product! Its like adult Legos.
Thank you for asking! We currently have the 90 degree gusseted brackets, but we do make angled joining plates for the 10, 15, and 40 series that would allow for other connection angles.
Hi, I have selected 40-4040 T-slotted profile, so which size nut can I use in that for corner joint? Depth of the nut shoulder should be considered for this selection or not. Can you please help me
Thanks for the question. A standard Slide-In Economy T-nut, part# 40-1961, is what we recommend for 40 series corner brackets. Bolt size varies depending on profile series and corner bracket style. When selecting a corner bracket style, be sure to check out the "Suggested Hardware" section in the catalog, or online, to ensure you have compatible hardware for your fastener.
