The standard for high-strength fastening.

Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

Often used to fasten parts in engines and turbines, these are our strongest stainless steel screws. They are comparable in strength to alloy steel with the corrosion resistance of 18-8 stainless steel.

Plastic screws are chemical and oil resistant, nonconductive, and lightweight.

Made of alloy steel, these low-profile screws are nearly twice as strong as their stainless steel counterparts. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

Made from alloy steel, these screws are nearly twice as strong as stainless steel low-profile screws. With a head height one-third the size of a standard socket head, they fit in the tightest spaces.

With a tensile strength of 170,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and are nearly two and a half times stronger than stainless steel thread-locking screws. They have a thread locker to prevent loosening from vibration.

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.

Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications.

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws.

Made from 18-8 stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

More corrosion resistant than 18-8 stainless steel screws, these metric screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.

Comparable to Class 12.9 steel.

The metric-sized threads on these screws are the same diameter as the shoulder. Comparable in strength to Class 12.9 steel.

With inch-sized threads the same diameter as the shoulder, these screws can handle heavy loads. They’re 18-8 stainless steel for good chemical resistance.

These metric screws have a head height that's about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

These metric 316 stainless steel shoulder screws are more corrosion resistant than 18-8 stainless steel shoulder screws. They also have excellent resistance to chemicals and salt water.

These alloy steel set screws have a thin edge that digs into hard surfaces for a secure hold. They're available in metric sizes.

These metric 316 stainless steel set screws have excellent chemical resistance and can be used in saltwater environments.

These metric set screws have a tip that makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

Also known as dog-point set screws, these metric set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned. Made of 18-8 stainless steel, they have good chemical resistance.

These metric set screws have a rolling ball that swivels 360° to minimize surface damage and allow for slight adjustments without loosening the screw.
