2 Pack M8 x 40mm (5/16" x 1-5/8") Thread Replacement Star Hand Knob Tightening Screw

This fixed my canopy swing. These are much better quality than the ones the swing came with which were plastic. The size was a fit and priced well! These screws will hold up more than the plastic.

This was a game changer. I ordered this use on my adjustable pool basketball hoop. It was perfect!!

Thread was perfect for what I needed it for

This worked perfectly to anchor my umbrellas in their stands. Over the years the threads on the old ones became stripped and we had a sudden strong storm and all of the umbrellas went flying! The new ones hold it in tightly so that won’t happen again. Reasonably priced. Just be sure to measure your old one so you get the right size.

Perfect replacement for the ones in my umbrella stand that had rusted and the caps had broken off of. These seem to be great quality and they work perfectly

Just be sure when you order this item that you know what size you’re working with.

I bought these to use with 5/16 T-nuts that accept 5/16" bolts. They say M8 is the same as 5/16. I could not thread these into the female T-nuts I installed. If you need a specific diameter bolt, choose that and don't accept that M8=5/16";

Good product although I ordered wrong size
