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

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

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.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Use these low-profile screws where space is limited.

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

These screws have good chemical resistance. A thread locker bonded to the threads prevents loosening from vibration.

A rubber O-ring under the head of these screws prevents leaks and seals out contaminants.

The nylon patch bonded to the threads of these socket head screws adds friction to keep vibration from loosening them, while their O-ring prevents leaks and seals out contaminants.

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. 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.

These metric brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

These metric set screws have good chemical resistance.

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.

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

These metric set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned. They're also known as dog-point set screws.

A low-profile flat-faced ball tip allows these metric set screw to be used in low-clearance applications.
