Choose these screws for their adherence to strict military standards for material and construction.

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.

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

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.

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.

Our most corrosion-resistant metal screws, titanium screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio and are about 40% lighter than steel screws.

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

More corrosion resistant than stainless steel screws, nickel alloy screws have excellent resistance to salt water and some acids.

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.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Their ultra-low-profile lets them fit in the tightest spaces.

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

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.

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.

With a tensile strength of 180,000 psi, these alloy steel screws are among the strongest we carry. They are stronger than Grade 8 steel screws and more than two and a half times stronger than stainless steel screws with split lock washer. The split lock washer helps to resist vibration.

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.

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

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

No need for separate bits—these screws lock directly onto square-drive socket wrenches, reducing the risk of dropping parts during installation.

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

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.

Closely spaced threads on these screws fit in holes with a fine pitch. They're not compatible with standard metric threads.

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

Made from alloy steel, these screws are twice as strong as standard steel Torx flat head screws.

Lower strength than alloy steel, use these screws for light duty fastening.

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

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

Stainless steel screws have excellent corrosion resistance in most environments.

A tamper-resistant hex drive (also known as pin-in hex drive) makes these screws difficult to remove without special tools.

With a tamper-resistant Torx drive (also known as a pin-in Torx drive), these metric screws are difficult to remove without special tools.

Prevent unwanted removal, leaks, and contamination with these sealing Torx screws.

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

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

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

316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They may be mildly magnetic.
