Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening. Made from 18-8 stainless steel, these screws have good chemical resistance.

Use these kits to connect plastic pipe flanges—they’re sized for Class 150 flanges made to ASME B16.5 dimensions. They come with screws, nuts, and washers that match the size and number of bolt holes for each pipe size.

Install these screws with a wrench or a screwdriver. Made from stainless steel, they have good corrosion resistance. A flange under the head means a separate washer is not necessary.

For strength comparable to that of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength. The flange eliminates the need for a separate washer.

Made from 18-8 stainless steel, these screws have good chemical resistance. They have a thread locker to prevent loosening from vibration.

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

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

Press threads into plastic to create a strong hold. Use a wrench, hex socket bit, or nutdriver to securely grip the hex head and tighten these screws.

Mount components to your enclosure without worrying about leaks—these kits seal out water from washdowns, rain, and snow when used with enclosures rated NEMA 4X.
