Stainless Steel Extended-Tip Thumb Screws

Corrosion resistant with an extended tip that acts like a dowel to fit into mating holes, align and hold parts together, and prevent cross-threading. Fasten these screws in workpieces that you regularly reposition or align. The knurled texture on the head creates extra grip as you twist. Also known as dog-point and pilot-point thumb screws.

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.

Steel Four-Arm Extended-Tip Thumb Screws

Four arms and an extended tip help you guide these screws into holes with greater control. The arms of the head have more surface area to grip than knurled-head thumb screws. The extended tip acts like a dowel—it fits into mating holes, aligns and holds parts together, and prevents cross-threading. Use these screws for workpieces that you regularly reposition or align. Also known as dog-point and pilot-point thumb screws.

Length is measured from under the collar.

Black-Oxide Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.
