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.
