The standard for high-strength fastening.

A Torx-Plus drive has more points of contact than a hex drive, allowing you to tighten these screws with less slippage or damage to the recess.

Choose these screws for their adherence to strict military standards for material and construction. Screws are 18-8 stainless steel for good chemical resistance.

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

These screws are hardened to be 40% stronger than standard 316 stainless steel screws, yet they still have excellent corrosion resistance. Use them in chemical and marine applications.

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Aluminum screws are one-third the weight of steel and have good corrosion resistance.

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.

Made from alloy steel, these screws are nearly twice as strong as stainless steel low-profile screws. With a head height one-third the size of a standard socket head, they fit in the tightest spaces.

With a tensile strength of 170,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and are nearly two and a half times stronger than stainless steel thread-locking screws. They have a thread locker to prevent loosening from vibration.

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They have a thread locker to resist vibration.

With a tensile strength of 170,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and are more than twice as strong as stainless steel wire-lockable screws. These resist vibration better than any other socket head screw.

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

18-8 stainless steel button head screws have good chemical resistance and may be mildly magnetic.

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

Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

These screws have a Torx or Torx-Plus drive for more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

Made from alloy steel, these 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 screws have excellent resistance to chemicals and salt water. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

Made from 18-8 stainless steel, these 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.

These 18-8 stainless steel 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 18-8 stainless steel 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.

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