Steel Knurled-Head Thumb Screws

Fasten panels and covers by hand. The knurled texture of the head creates extra grip as you twist.

Length is measured from under the head.

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.

Steel Raised-Profile Knurled-Head Thumb Screws

The raised head gives your fingers extra space to grab these thumb screws, even with oily fingers. The knurled texture creates extra grip as you twist. Install these thumb screws on panels and covers for routinely serviced equipment, such as HVAC access doors and machine safety shields.

Length is measured from under the collar.

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.
