Steel Socket Head Screws
 |
Fully Threaded |
 |
Partially 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.
Zinc-Plated Alloy Steel—A common choice for areas with occasional exposure to moisture.

Steel Hex-Drive Flat Head Screws
 |
Our strongest hex-drive flat head screws. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.
Length is measured from the top of 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.
Zinc-Plated Alloy Steel—A common choice for areas with occasional exposure to moisture.
Standard Profile—Standard-profile heads are the most common choice for flat head 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.

Sealing Socket Head Screws
 |
 |
Fully Threaded |
Keep out dust and contaminants and lock in air and fluid. As you tighten these corrosion-resistant screws, a rubber O-ring under the head compresses to form a tight seal. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.
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 screws can.
Buna-N O-Ring—These seals won't swell or soften when they touch oil, grease, or fuel.
Viton® Fluoroelastomer O-Ring—Our most chemical-resistant seals. They withstand oil, grease, fuel, solvents, synthetic lubricants, and acids, even at high temperatures.

Steel Wire-Locking Socket Head Screws
 |  |
Fully Threaded |
Our most vibration-resistant steel socket head screws. To lock them in place, secure a wire (sold separately) through a hole in their head. These screws won't loosen in moderate to heavy vibration. Made of alloy steel, they're some of our strongest screws. Their deep, six-point socket keeps hex keys 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.

Brass Button Head Hex-Drive Screws
 |
These button head 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 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.
