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.

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.

Nylon-Tip Stainless Steel Set Screws
 |
These corrosion-resistant set screws have a soft nylon tip to secure delicate surfaces, such as glass, plastic, or polished metals. However, if you need a stronger tip, opt for screws with brass or silver tips. The stainless steel body won't rust, but it's not as strong as alloy steel.
