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.

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

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.

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.

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.

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

The Torx or Torx-Plus drive on these metric screws have more points of contact than other drives, allowing you to tighten them 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.

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.

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

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

Known for their strength, these alloy steel screws are coated to provide corrosion resistance in wet environments.

Comparable in strength to Grade 8 steel. These screws have inch thread sizes.

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.

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

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.

These metric screws have a head height that's about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.

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.

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.

Made from alloy steel, these inch size set screws have a thin edge that digs into hard surfaces for a secure hold.

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

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.

Made from black-oxide alloy steel, these set screws resist corrosion in dry environments. They dig into hard surfaces for a secure hold and have serrations on the cup edge that grip the material surface to resist loosening.

The tip makes good contact on flat surfaces and allows you to make frequent adjustments with minimal surface damage.

Strong and durable, these alloy steel set screws hold objects tightly against flat surfaces.

These alloy steel set screws have an extra-soft nylon tip, which minimizes the damage that can occur from metal-on-metal contact. Use them set screws on soft surfaces such as aluminum.

With a tip that's harder than nylon and silver, these alloy steel set screws provide a secure hold on hard surfaces. The body has a black-oxide finish to resist corrosion in dry environments.

Made of alloy steel, these set screws are often used in U-shaped and V-shaped grooves and on other sloped or angled surfaces. The oval tip allows for frequent adjustments with minimal surface damage.

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.

Use the square head to turn these screws by hand, or use a wrench when you need more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned.

A nylon locking patch grips threads to resist loosening.

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

A rolling ball swivels 360° to minimize surface damage and allow for slight adjustments without loosening the screw.

Also known as jam set screws, these lock other screws in place, hold pins, and adjust spring tension. A black-oxide finish provides corrosion resistance in dry environments.

These set screws have a low-profile flat-faced ball tip for use in low-clearance applications.

Set screws exert pressure at the tip to hold objects in place.

Shoulder screws have a cylindrical shoulder under the head that allows parts to rotate around or slide along its length. They have a standard shoulder with an undersized tolerance to fit most machinery and equipment.

A zinc plating provides corrosion resistance in wet environments.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

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

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

Thread these one-piece collars onto an Acme lead screw.

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start metric ball screws and nuts, these have a single thread that runs the length of the screw.

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

A set of ball bearings reduces friction and secures the end of a metric ball or lead screw.
