Stainless Steel Wing Thumb Screws

Corrosion resistant with a wing shape that's easy to grab. These thumb screws offer more leverage than spade-head thumb screws. Use these screws to fasten panels and covers that need frequent access.

Length is measured from under the head.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws resist rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
