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.

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.

A freely rotating but permanently attached 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.

Nonconductive and softer than brass, the nylon tip reduces vibration and eliminates damage from metal touching metal.

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

With threads the same diameter as the shoulder, these inch-sized screws can handle heavy loads. They’re comparable to Grade 8 steel.

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.

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.

Made of lubricant-filled nylon, these screws have a slippery surface to resist wear in high-friction applications.

Nickel alloy shoulder screws are more resistant to acids and salt water than stainless steel shoulder screws.

One-third the weight of steel, aluminum shoulder screws are lightweight and have good corrosion resistance.

Available in metric sizes, these screws have a locking element on the threads that adds friction to resist loosening. Comparable to Grade 8 steel, they are the strongest screws we offer.

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.

These shoulder screws have good chemical resistance.

These shoulder screws are angled under the head to sit flush in countersunk holes.

Screw these shoulders onto a stud.

These shoulder screws come with a traceable lot number and material test report.

Install and remove these metric shoulder screws by hand or with a hex key.

Made of 416 stainless steel, these shoulder screws are almost twice as strong as 18-8 stainless steel and have the same corrosion resistance.

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

Comparable to Grade 8 steel, these screws are the strongest precision shoulder screws we offer.

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

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.

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

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

Made from alloy steel, these screws are three times stronger than standard steel button head Torx screws. A Torx-Plus drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

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.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. Torx drives have more points of contact than other drives, allowing you to tighten the screw without damaging the recess.

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

Create a decorative appearance on your finished product—the head of these screws is painted.

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.

18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange distributes pressure across a wide surface, eliminating the need for a separate washer.

These metric 316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

These aluminum screws are lightweight and resist corrosion in wet environments. They have a flange that is wider and thicker than our other flanged screws, so they distribute pressure the best.

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.
