Anyone who has ever had to purchase hardware for a boat knows that anything labeled as “marine” is automatically five times more expensive. I have dropped more thumb screws for our boat Bimini top into the water than I would care to admit and find that the “marine Bimini screws” are ridiculously overpriced. After a quick search for the thread count and screw size I have a bag of thumb screws and can now be clumsy without also being broke. 5 stars. Would recommend.

Delivered what was advertised. Good. Quality, should last many wears

Seems to be good quality stainless screw. The handle is big and easy to turn. These seem very sturdy and I have not managed to break one yet. I was not gentle on them. Very happy with these.

Great Product

Failed almost immediately.The plastic wing part of this screw is cheap and weak at best. If I could have given zero stars I would. I think this company owes me a lot of stars. Yes it was that bad.They won’t take any torque at all before the plastic piece falls right off.
