Use these hex drive screws and binding barrels as a low-profile alternative to standard nut and bolt combinations.

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.

As strong as alloy steel and about 40% lighter, these metric titanium screws are known for their high strength-to-weight ratio. They stand up to salt water, acids, and chemicals.

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.

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

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

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.

With a flange comparable in size to a washer, these metric screws distribute pressure better than standard flanged screws. Made from 316 stainless steel, they have excellent resistance to chemicals and salt water. Screws may be mildly magnetic.

Made from aluminum, these metric screws are lightweight and resist corrosion in wet environments. 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.

Nearly twice as strong as stainless steel button head screws, these metric screws are made from alloy steel. Their tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

Install and remove these metric shoulder screws by hand or with a hex key.

Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount, or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components.

The metric-sized threads on these screws are the same diameter as the shoulder. Comparable in strength to Class 12.9 steel.

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.

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.

Install these socket head screws through a hole and thread on a retainer to keep secure—no special tools are required.

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.
