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.

Blue-Dyed Zinc-Plated Alloy Steel—The distinctive blue color makes it easy to tell these metric-sized screws apart from inch screws.

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.

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.

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

Steel Cup-Tip Set Screws

Made of alloy steel, these screws are strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.

Steel Flat-Tip Set Screws

Spread out holding power and protect surfaces from damage. Unlike cup and cone tip screws, the flat tip on these distributes pressure evenly, reducing marring but not holding as tightly. They're a good choice for repositioning parts frequently on jigs, fixtures, and other applications where the tip presses against a flat surface. Made of alloy steel, these screws are strong enough to hold components without wearing down.

Easy-Adjust Steel Ball-Tip Set Screws

Keep pressure consistent on workpieces that aren't fully flat or parallel. A rolling ball on the tip of these screws maintains contact and swivels 360° to make small adjustments without loosening. Made of alloy steel, they are strong enough to hold components without wearing down.

Made-to-Order Same-Size Thread Stainless Steel Hex-Drive Shoulder Screws

Harness superior holding power with custom-shoulder-length screws that also won't rust. These are ideal for replacing fasteners in older machines or for testing prototypes. Threads that match the shoulder diameter give them a tighter hold than screws with a standard thread diameter. Use them in thicker materials and larger holes.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
