Made to Japanese Industrial Standards, these Class 10.9 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange eliminates the need for a washer.

Made from 18-8 stainless steel, these screws have good chemical resistance. A flange under the head distributes pressure over the surface, eliminating the need for a washer.

Choose these metric screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are about 10% stronger than medium-strength steel screws. Their serrated flange helps to resist vibration.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. A serrated flange provides mild vibration resistance.

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.

Comparable to Class 12.9 steel.

With a reduced head size and an unthreaded shoulder, use these screws as a shaft or dowel pin for small rotating parts in low-clearance applications.

Available in metric sizes, these screws have a locking element on the threads that adds friction to resist loosening. Comparable to Grade 8 steel, they are the strongest screws we offer.

With a shoulder that’s twice as precise as standard shoulder screws, these metric shoulder screws act as a shaft or axle for bearings and other moving parts in applications that require smooth and accurate movement, such as measuring and lab equipment. Made of 18-8 stainless steel, they’re nearly as strong as steel but won’t rust in outdoor or washdown environments.

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.

316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They may be mildly magnetic.

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

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

18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. A Torx drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

Made from A286 stainless steel, these metric screws provide the strength of alloy steel and the corrosion and chemical resistance of 18-8 stainless steel. They have a Torx drive that has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

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.

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Made from 18-8 stainless steel, these metric 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 metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.

To vent fluid and gas trapped under the screw, these metric screws are drilled through the shaft. Made from 18-8 stainless steel, they 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 metric brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.
