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

These metric alloy steel 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. Their tamper-resistant Torx drive (also known as a pin-in Torx drive) makes them difficult to remove without special tools.

Made from Grade 8 steel, these 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.

Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

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

These screws have good chemical resistance and may be mildly magnetic.

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.

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

18-8 stainless steel screws have good chemical resistance.

A free-rotating, permanently attached washer distributes holding pressure over a wider area than a flange and remains stationary to prevent scratching the material surface as you tighten the screw.

These steel screws are available with corrosion-resistant finishes.

These steel screws save you time and effort by drilling their own holes and fastening in a single operation.

These screws are beveled under the head for use in countersunk holes.

These steel screws have corrosion-resistant finishes.

These steel screws have a black-oxide or zinc-plated finish to resist corrosion.

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.

Made from 18-8 stainless steel, these inch-sized shoulder screws have good chemical resistance.

With inch-sized threads the same diameter as the shoulder, these screws can handle heavy loads. They’re 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 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.

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

Made from alloy steel, these metric set screws have a thin edge that digs into hard surfaces for a secure hold. They have a nylon locking patch that grips threads to resist loosening.

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.

A nylon locking patch grips threads to resist loosening.

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

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.

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

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

These metric thumb screws have a thin, knurled head for use in low-clearance applications. They have a black-oxide finish to resist corrosion in dry environments.

A raised head makes these thumb screws easy to grip. They have a black-oxide finish to resist corrosion in dry environments.

These steel thumb screws have a black-oxide finish to resist corrosion in dry environments.

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

A wide tip provides more gripping power than standard swivel-tip thumb screws. To use, remove the tip, thread the screw through the hole, and attach the tip on the other side.

A large swivel angle allows these thumb screws to make better contact with angled and uneven surfaces than nonremovable swivel-tip thumb screws.

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Use these hex drive screws and binding barrels as a low-profile alternative to standard nut and bolt combinations.
