Steel Hex Head Screws
 |  |
Fully Threaded | Partially Threaded |
Our most popular hex head screws. These have a head with six flat sides to keep wrenches and sockets from slipping and rounding off the drive.
Length is measured from under the head.
Extreme-Strength Fastener—Our strongest hex head screws hold up in your most demanding high-stress applications. They have a tensile strength of 170,000 psi and higher.
Zinc-Yellow-Chromate-Plated Steel—With slightly better corrosion resistance than zinc-plated steel screws, these stand up to more frequent exposure to moisture.

Steel 12-Point Screws
 |  |
Fully Threaded | Partially Threaded |
Good for high-strength fastening, these screws are made from steel comparable in strength to Grade 9 steel. Use them for heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. The head makes 12 points of contact with a wrench to handle more torque than a socket head or hex head screw. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. To install, use a 12-point wrench that matches the head width of your screw.
Black Oxide—Black-oxide coated screws are mildly corrosion resistant in dry environments.

Steel Flanged Hex Head Screws
 |
Fully Threaded |
 |
Partially Threaded |
Our most popular flanged hex head screws. These have a flange that spreads pressure over a wide area to protect thin and soft materials. The head's six flat sides keep wrenches and sockets from slipping and rounding off the drive.
Head height includes the flange. Length is measured from under the flange.
Extreme-Strength Fastener—Our strongest hex head screws hold up in your most demanding high-stress applications. They have a tensile strength of 170,000 psi and higher.
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.

Steel Torx Plus Socket Head Screws
 |
Fully Threaded |
 |
Partially Threaded |
The deep, six-lobe socket of these Torx screws withstands even more wear and torque than hex drives. They resist stripping, even after repeated tightening. These screws are a good choice for equipment that requires frequent adjustments, such as jigs. Made of alloy steel, these are our strongest socket head screws.
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.

Steel Socket Head Screws with Split Lock Washer
 |
Light vibration won't loosen these screws. As you twist, the uneven ends of the washer bite into the screw and mating surface for a tight hold. Also known as Sems screws, the washer rotates freely but is permanently attached. These are our strongest alloy steel 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.

Thread-Locking Steel Hex-Drive Shoulder Screws
 |
Immune to vibration, these screws won't loosen and are also fit for high-strength fastening. A threadlocker pellet is embedded into their threads, saving you the hassle of adding it yourself. The pellet compresses as the screw is tightened, which gives it more locking power than a patch. These screws are twice as strong as other standard-fit thread-locking shoulder screws, but will rust if exposed to moisture or chemicals.
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.
