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

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

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.

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

These screws have good chemical resistance. A thread locker bonded to the threads prevents loosening from vibration.

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

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.

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

Designed for use in food, pharmaceutical, and other sanitary environments, these screws have an extra-wide truss head that distributes holding pressure to reduce the likelihood of crushing thin materials.

Choose these metric screws for fastening most machinery and equipment. They are twice as strong as low-strength steel screws.

Choose these metric screws for heavy duty stamping applications as well as earth-moving machinery such as bulldozers and excavators. These screws are 10% stronger than our high-strength metric steel screws.

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

Plastic screws are chemical and oil resistant, nonconductive, and lightweight.

Designed for construction and exterior building applications, these metric screws are often used to join I-beams and scaffolding. Their partial threading leaves an unthreaded portion that is strong enough to stand up to the sideways forces of joints.

Made to Japanese Industrial Standards, these Class 10.9 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange eliminates the need for a washer.

Made from 18-8 stainless steel, these screws have good chemical resistance. A flange under the head distributes pressure over the surface, eliminating the need for a washer.

Choose these metric screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are about 10% stronger than medium-strength steel screws. Their serrated flange helps to resist vibration.

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

These metric brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Use these screws in thin materials; they have a shorter threaded portion than our standard shoulder screws. They’re comparable in strength to Grade 8 steel.

These screws have metric thread sizes. They are 18-8 stainless steel for good chemical resistance.

For metric thread sizes with excellent resistance to chemicals and salt water, choose these 316 stainless steel shoulder screws.

These metric set screws have good chemical resistance.

These metric 18-8 stainless steel set screws are chemical resistant. The tip makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

Secure gears, pulleys, and other objects that require frequent adjustments, even in wet environments.

Also known as dog-point set screws, these metric set screws have a protruding tip that locks within a mating hole or slot to keep parts aligned. Made of 18-8 stainless steel, they have good chemical resistance.

Turn these metric screws by hand using the hex head, or tighten them with a wrench for extra torque. With an extended tip that locks into a mating hole or slot—sometimes known as a dog point—they are often used to align and secure parts such as gears and pulley wheels.

These metric set screws have a rolling ball that swivels 360° to minimize surface damage and allow for slight adjustments without loosening the screw.

These metric thumb screws have arms that provide a flat surface to push your fingers against.

These bolts have good chemical resistance. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

These metric Grade B7 threaded rods 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 about half the strength of medium-strength steel threaded rods for light duty hanging, mounting, and fastening.

These metric threaded rods tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. About half the strength of medium-strength steel threaded rods, use them for light duty hanging, mounting, and fastening.

Class 12.9 rods are about 20% stronger than Class 10.9 threaded rods and are for use in heavy machinery.

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.

Fiberglass threaded rods are stronger than nylon threaded rods. They resist acids, solvents, salt water, and oil.

Install with a driver.

Fasten from the nose end with a wrench for more torque than slotted long-nose spring plungers.

Lock the nose into the retracted position by pulling the knob and rotating it 90°.

Lock the nose into the retracted position by pulling the handle and rotating it 90°.

Lock the nose into the retracted position by pulling the ring and rotating it 90°.

Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench.

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.

Often called sleeve nuts, these thread adapters fasten parts with right-hand threads to parts with left-hand threads.

Multiple thread channels (also known as thread starts) create faster linear travel than lead screws with a single thread start.

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

Also known as tap-end and fixture studs, these rods have friction-fit threads on one end to resist loosening and standard threads on the other side for attaching a nut.

For mounting items to your machine table, these kits contain the full system of necessary components.

Also known as nut eyebolts, these are designed for through-hole applications.

Route wire and cable through the smooth eye without snagging.

Designed for use with right-hand, externally threaded rod ends, these rods have right-hand threads on both ends. Use them for remote valve operators, throttle controllers, shifting mechanisms, and virtually any push/pull assembly.

Similar to turnbuckles, these rods have right-hand threads on one end and left-hand threads on the other so you can make a linkage that adjusts for tension.
