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.

These screws are specially tempered to meet ASTM A193 specifications for temperatures up to 1100° F.

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.

Stainless steel screws have excellent corrosion resistance in most environments. Wire these screws together for more vibration resistance than other types of socket head screws.

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

The nonmarring brass tip is electrically conductive and harder than nylon, but soft enough to conform to most surfaces and reduce damage from metal-on-metal contact.

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

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Torx and Torx-Plus drives have 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.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

To prevent unwanted removal, these metric screws have a tamper-resistant Torx drive—also known as a pin-in Torx drive—that makes them difficult to unscrew without special tools. An O-ring under the head blocks leaks and seals out dust and dirt.

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

Choose these screws for their adherence to strict military standards for material and construction. Their high tensile strength means they can be used in demanding, high-stress applications.

About half as strong as medium-strength steel screws, these screws can be used for light duty fastening applications, such as securing access panels.

Use these kits to connect standard-size stainless steel pipe flanges for ANSI Class 150 or 300.

The most common heavy hex head screw, these steel screws meet ASTM A325 regulations for structural joints, such as mating I-beams and scaffolding.

These Grade B8 screws are made from 18-8 stainless steel and have good chemical resistance. Also known as pressure bolts, they meet the high-pressure and high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

These Grade B7 steel screws are nearly twice as strong as our stainless steel screws for high-pressure applications. Also known as pressure bolts, they meet the high-pressure, high-temperature regulations of ASTM A193 and are used to secure pressure tanks, valves, and flanges.

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

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

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

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

Stainless steel screws have excellent corrosion resistance in most environments.

These steel screws are hot-dipped galvanized to resist corrosion in wet environments.

Comparable to Class 12.9 steel.

A locking element on the threads adds friction to resist loosening. Comparable to Grade 8 steel, these alloy steel shoulder screws are the strongest we offer.

These alloy steel set screws have a thin edge that digs into hard surfaces for a secure hold. A nylon locking element grips threads to resist loosening.

A nylon locking patch grips threads to resist loosening.

These metric set screws have a brass tip, which is harder than nylon and silver, for a secure hold on hard surfaces. The body has a black-oxide finish to resist corrosion in dry environments.

Also known as half dog-point set screws, these set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned.

Also known as full dog-point set screws, the tip is twice as long as the tip on other extended-tip set screws for greater engagement in deep mating holes.

These alloy steel set screws have a pointed tip that wedges into the contact surface for a secure hold on soft materials such as brass.

About half the strength of medium-strength bolts, these bolts are for light duty fastening. Carriage bolts have a smooth, rounded head for a finished look. The knurled neck grips the inside of the hole to keep these bolts from turning when tightening a nut.

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

Drive these hangers into wood with an adjustable wrench, pliers, or a special driver bit.

The tensile strength of these metric Grade B7 rods is about one and a half times higher than low-strength steel rods.

Drive and secure these threaded rods on both ends with the included nuts. They’re Grade B7, so their tensile strength is about one and half times higher than low-strength steel rods.

Grade B16 threaded rods maintain their strength at higher temperatures than Grade B7 threaded rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

Grade B8 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges. They have good chemical resistance.

These metric 316 stainless steel threaded rods are more corrosion resistant than 18-8 and 410 stainless steel threaded rods and have excellent resistance to chemicals and salt water.

These hardened 316 stainless steel threaded rods are 40% stronger than standard Grade B8M threaded rods. They meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

These metric threaded rods are made from nylon 6/6 and resist oil, grease, and solvents. They’re nonconductive, making them good for use around sensitive electrical components.

Bronze threaded rods are stronger and more resistant to salt water than brass rods.

These assortments include button head screws.

A nylon patch bonded to the threads adds friction, preventing these standoffs from loosening from vibration.

These stud anchors strengthen the parts of buildings where steel framing connects to concrete. They’re also known as Nelson studs.

In addition to joining male- and female-threaded parts, these adapters can increase or decrease metric thread sizes and change the thread pitch.

Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection.

One side inch, one side metric, and a hex in the middle—these handy fasteners connect two female-threaded parts, such as coupling nuts, adapting from inch threads to metric. Tighten with a standard wrench.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.
