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.

Choose these screws for their adherence to strict military standards for material and construction. Screws are 18-8 stainless steel for good chemical resistance.

Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening. Made from 18-8 stainless steel, these screws have good chemical resistance.

Often used to fasten parts in engines and turbines, these are our strongest stainless steel screws. They are comparable in strength to alloy steel with the corrosion resistance of 18-8 stainless steel.

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

Our most corrosion-resistant metal screws, titanium screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio and are about 40% lighter than steel screws.

More corrosion resistant than stainless steel screws, nickel alloy screws have excellent resistance to salt water and some acids.

Nearly as strong as steel, these stainless steel screws won’t rust in outdoor, washdown, and other corrosive environments. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

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. Their ultra-low-profile lets them fit in the tightest spaces.

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

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 nearly two and a half times stronger than stainless steel thread-locking screws. They have a thread locker to prevent loosening from vibration.

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.

For use where sideways forces are a concern, these screws have a precisely measured unthreaded portion (grip) for a strong hold. Their flanged head distributes pressure where the screw meets the surface, so you don't need a washer.

A rubber O-ring under the head of these screws prevents leaks and seals out contaminants.

Fasten these screws inside a high-vacuum system without bringing in contaminants.

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.

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.

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 shoulder screws are chemical resistant, nonconductive, and lightweight.

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

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.

These shoulder screws have good chemical resistance.

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

With a shoulder that’s twice as precise as standard shoulder screws, these metric shoulder screws act as a shaft or axle for bearings and other moving parts in applications that require smooth and accurate movement, such as measuring and lab equipment. Made of 18-8 stainless steel, they’re nearly as strong as steel but won’t rust in outdoor or washdown environments.

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

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

These screws have a head height about one-third the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.
