Steel Socket Head Screws

Fully Threaded

Made of alloy steel, these screws are the standard for high-strength fastening. Use them in high-load applications such as dies, presses, and heavy equipment. The deep, six-point socket keeps the hex key from slipping out and damaging the drive.

Length is measured from under the head.

Black-Oxide Alloy Steel—Best for dry environments since moisture will cause these screws to rust. They have a dark, matte appearance.

Stainless Steel Phillips Flat Head Screws

These screws are made of stainless steel, so they won't rust or corrode when exposed to moisture and chemicals. The Phillips drive has a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.

Length is measured from the top of 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.

Standard Profile—Standard-profile heads are the most common choice for flat head screws.

Steel Pan Head Phillips Screws

Our most popular steel pan head screws. 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.

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.

JIS Steel Pan Head Screws

These screws are manufactured to meet Japanese Industrial Standards. Similar in appearance to Phillips, the JIS drive has a shallower opening with sharper angles and straighter internal walls. This lets them withstand more torque while preventing the driver from slipping and damaging the drive. Tighten them only with a JIS driver to avoid stripping the drive. Some JIS screws are marked with a dot near the drive for quick identification. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads.

Length is measured from under the head.

Steel Pan Head Slotted Screws

These pan head screws have the simplest drive style. With only two contact points, the slotted drive can't withstand much torque, so it's best to hand-tighten them. They have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads.

Length is measured from under the head.

Stainless Steel Button Head Torx Screws

Our most corrosion-resistant button head Torx screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With a deep six-lobe opening, the Torx drive prevents your driver from slipping and stripping the drive. Also known as star drives, they withstand more torque than slotted, Phillips, and hex drives.

Length is measured from under the head.
