Stainless Steel Flared-Collar Knurled-Head Thumb Screws

A flared collar leaves more space for your fingers to grasp these corrosion-resistant thumb screws. It also serves as a decorative finish. The knurled texture on the head creates extra grip as you twist.

Length is measured from under the collar.

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.
