The standard for high-strength fastening.

Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening.

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

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water.

These screws are hardened to be 40% stronger than standard 316 stainless steel screws, yet they still have excellent corrosion resistance. Use them in chemical and marine applications.

Our most corrosion-resistant metal screws, titanium screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio and are about 40% lighter than steel screws.

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.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They have a thread locker to resist vibration.

Stainless steel screws have excellent corrosion resistance in most environments. Wire these screws together for more vibration resistance than other types of socket head screws.

For use where sideways forces are a concern, these screws have a precisely measured unthreaded portion (grip) for a strong hold. Their flanged head distributes pressure where the screw meets the surface, so you don't need a washer.

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

A freely rotating washer distributes pressure over a wider area than a flange, preventing damage to your material's surface.

Nonconductive and softer than brass, the nylon tip reduces vibration and eliminates damage from metal touching metal.

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

These steel pan head screws are coated for corrosion resistance.

A zinc plating provides mild corrosion resistance.

Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

Brass pan head screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

Made from brass, these screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.

These 18-8 stainless steel button head screws have good chemical resistance and may be mildly magnetic. The tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.

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.

These screws have good chemical resistance and may be mildly magnetic.

Choose these screws for their adherence to strict military standards for material and construction.

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Made from alloy steel, these screws are twice as strong as standard steel Torx flat head screws.

These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic.

A zinc plating provides mild corrosion resistance.

Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws.
