TOPINSTOCK M5 x 20mm T Sliding Bolt for European 20 Series Aluminum Profile Pack of 25

I purchased the bolts to add accessories to my Palram Snap and Grow greenhouse M6 or M8 would be better but I couldn’t find any at the time, Palram does sell them but not at this price.

They work great

Most of them are as advertised but received a few with no threads

I bought these to fit the 8020 20 mm rail also sold here on amazon. They do not fit this extrusion. Maybe they fit others but the T and the shoulder are too big

Tiny, tiny, tiny!Does not fit 80/20 T-slot, these are like mini versions of the real ones from 80/20 Inc.No wonder they were so cheap, do not buy unless you have the tiniest T-slot known to man.
