Aluminum Alloy Thumbscrew Set (Extension)+ Wrench (Black)

I don’t know what everyone’s talking about that the wrench doesn’t work or fit. Mine fits perfectly fine to tighten down the thumbscrew . Cheap. Nice. Sturdy. No complaints.

I bought these for an MTB night riding light with a GoPro connector. Using these really keeps it in place since you can crank on the sucker so it won’t budge.

Nice quality, works perfect.

These are much better designed than the original screw that came with my GoPro. The large, knurled knobs make tightening and loosening much easier than the stock plastic-handled ones, and now I can do it with my riding gloves on. While riding my motorcycle, the GP was always slipping down with the old screw as I could never get it tight enough (it's mounted on the right handlebar) - these screws get it tight the first time yet come loose easily when I'm ready to remove them. The included tool was useless - it was too small for the knob - but I didn't order these for that feature.

Great idea to extend the length of these GoPro screws as My big fingers can hardly reach the standard ones that come with the Go Pro. I just wish they were another 12mm longer at the knurled end to really finger tighten. At least the current product, I can get the wrench on it to tighten. However on some items with plastic parts, I would prefer the finger tighten to not destroy the part.
