Seal out contaminants and prevent leaks—a rubber O-ring under the head prevents leaks and seals out contaminants.

Fasten these screws inside a high-vacuum system without bringing in contaminants.

These general purpose flanged screws distribute pressure where the screw meets the surface, eliminating the need for a washer.

Choose these metric screws for fastening most machinery and equipment. They are twice as strong as low-strength steel screws.

These metric screws help prevent counterclockwise-moving parts from loosening. Use them for medium-strength fastening.

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

Choose these screws for their excellent corrosion resistance—comparable to 316 stainless steel—and the strength of steel. Use them for high-strength fastening in chemical and marine applications.

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.

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

The Torx or Torx-Plus drive on these metric screws have more points of contact than other drives, allowing you to tighten them without damaging the recess.

Add a decorative look when fastening parts—these metric screws have a painted head.

These metric 316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

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.

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

Turn these metric screws to the left to tighten; once fastened, they prevent loosening from counterclockwise motion. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

These metric thumb screws have a raised head that makes them easy to grip. A black-oxide finish provides corrosion resistance in dry environments.

These metric thumb screws have a thin, knurled head for use in low-clearance applications. They have a black-oxide finish to resist corrosion in dry environments.

With a slim profile, these metric thumb screws fit in tight spaces.

These metric thumb screws have a large head that allows you to grip them with your entire hand for greater torque while tightening than standard knurled plastic-head thumb screws.

These metric thumb screws are made of chemical-resistant 18-8 stainless steel. Also known as dog- and pilot-point thumb screws, insert the point into a drilled hole or slot to hold items in place.

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 A286 stainless steel screws have comparable strength to alloy steel with the corrosion resistance of 18-8 stainless steel.

With an O-ring under the head, these metric screws seal out leaks and contaminants while also preventing unwanted removal.

To vent fluids and gases trapped under the screw, these metric screws are drilled through the shaft.

18-8 stainless steel screws have good chemical resistance.
