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—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.

Stainless Steel Socket Head Screws
 |
Fully Threaded |

Partially Threaded |
These screws won't rust or corrode when exposed to moisture and chemicals. Their 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.
Highly Corrosion-Resistant 316 Stainless Steel—Superior to 18-8 stainless steel screws, these screws won't degrade when exposed to harsh weather, salt water, and most chemicals.

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.

Steel Thread-Locking Socket Head Screws
 |
Fully Threaded |
Lock parts in place on vibrating machinery. These screws have threads with a bonded nylon patch, saving you the time and mess of adding threadlocker yourself. Made of alloy steel, these are 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—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.
Steel Torx Plus Flat Head Screws
 |
The strongest Torx Plus flat head screws we offer. They're made of alloy steel, so they have nearly twice the tensile strength of other screws. With larger lobes than Torx drives, Torx Plus withstands even more torque 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.
Standard Profile—Standard-profile heads are the most common choice for flat head screws.

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.
