Self-Aligning Four-Arm Swivel-Tip Thumb Screws

The large tip on these thumb screws secures a bigger surface area than our other swivel-tip screws. It pivots to sit flat against uneven and angled workpiece surfaces without causing damage. Remove the tip to thread these screws through a hole, then reattach the tip on the other side. The four arms of the head create natural grooves for your hand to grip when fastening.

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.

Extra Large—To maximize surface contact, these are twice the size of the tip included with these thumb screws.

Acetal Tips—Nonmarring, so they're safe to use on delicate surfaces.

Self-Aligning Swivel-Tip Thumb Screws

Secure components at an angle or against uneven surfaces with these thumb screws. The tip pivots to conform to surfaces and is narrow enough to fit through threaded holes. The knurled texture of the head creates extra grip as you twist.

Length is measured from under the head.
