Stainless Steel Pan Head Phillips Screws

These stainless steel pan head Phillips screws won't rust or corrode when exposed to moisture and chemicals. They have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.

Length is measured from under the head.

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.

Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

Stainless Steel Button Head Hex-Drive Screws

These button head screws won't corrode from moisture and chemicals, but they aren't as strong as alloy steel screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.

Length is measured from under the head.

Brass Round Head Slotted Screws

These round head slotted screws have a shiny look and won't rust in damp environments. Made of brass, they're also conductive and nonmagnetic, making them useful for electrical applications. The round head has a domed profile that gives a smooth, decorative look. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them.

Steel Button Head Hex-Drive Screws

Made of alloy steel, these screws have nearly twice the tensile strength of other steel screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.

Length is measured from under the head.

Black-Oxide Alloy 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.

Stainless Steel Fillister Head Slotted Screws

The most corrosion-resistant fillister head slotted screws we offer. With a deeper drive than others, fillister heads reduce the likelihood that basic slotted drivers slip as you hand-tighten them. Since they also have a narrow diameter, they fit into tight spaces, such as holes tucked away inside machinery.
