Self-Aligning Steel Swivel-Tip Set Screws

Avoid the angst of angles and uneven surfaces. The tip on these set screws pivots to conform to your workpiece's surface without damaging it. Made of alloy steel, they are strong enough to hold components without wearing down.

Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.

Self-Aligning Steel Removable-Swivel-Tip Set Screws

Boost gripping power without increasing thread size. Unlike standard self-aligning screws, the tip diameter on these screws is 1/16" wider than the shaft, giving you more surface contact. Since their tip is removable, they still fit into the same size hole during installation. Made of steel, they're best for dry environments where they won't rust.

Black-Oxide Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.

Extra-Large Steel Tips—Offer more gripping strength than normal-sized tips.

Acetal Tips—Swap out the tip for a nonmarring one to protect delicate surfaces.

Tight-Clearance Self-Aligning Stainless Steel Swivel-Tip Set Screws

Our most corrosion-resistant swivel-tip set screws. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. With a low-profile tip, these screws fit in compact assemblies, shallow mounting holes, and precision equipment where space is limited. The tip pivots to conform to your workpiece's surface without damaging it.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.

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.

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.

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.

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.
