Thread-Locking Pan Head Phillips Screws

A nylon patch bonded to the threads adds friction to prevent loosening from vibration. Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic.

Metric Thread-Locking Pan Head Phillips Screws

These metric screws have a nylon patch bonded to the threads that adds friction to prevent loosening from vibration. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

Stainless Steel Thread-Locking
Button Head Hex Drive Screws

Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.

Metric Stainless Steel Thread-Locking
Button Head Hex Drive Screws

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. A nylon patch bonded to the threads adds friction to prevent loosening from vibration.

Alloy Steel Thread-Locking
Button Head Hex Drive Screws

Made from alloy steel, these screws are nearly twice as strong as stainless steel button head screws.

Vibration-Resistant Sealing Rounded Head Screws

A nylon patch bonded to the threads adds friction to resist loosening from vibration.

Flat Head Screws

Nylon Slotted Flat Head Screws

These screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Metric Nylon Slotted Flat Head Screws

These metric screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.

Metric Phillips Thread-Locking Flat Head Screws

A nylon patch bonded to the threads of these metric screws adds friction to prevent loosening from vibration. Made of 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

A nylon patch bonded to the threads adds friction to prevent loosening from vibration. Made of 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic.

Alloy Steel Thread-Locking
Hex Drive Flat Head Screws

Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws.

Stainless Steel Thread-Locking
Hex Drive Flat Head Screws

Stainless steel screws have excellent corrosion resistance in most environments.

Socket Head Screws

Plastic Socket Head Screws

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

18-8 Stainless Steel Thread-Locking
Socket Head Screws

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

Super-Corrosion-Resistant 316 Stainless
Steel Thread-Locking Socket Head Screws

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. They have a thread locker to resist vibration.

Alloy Steel Thread-Locking Socket Head Screws

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.

Vibration-Resistant Sealing Socket Head Screws

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.

Nylon-Tip Alloy Steel Socket Head Screws

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

Hex Head Screws

Plastic Hex Head Screws

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

High-Strength Grade 8 Steel
Thread-Locking Hex Head Screws

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 more than twice as strong as our stainless steel thread-locking screws. The thread locker helps resist loosening from vibration.

Medium-Strength Metric Class 8.8 Steel
Thread-Locking Hex Head Screws

These Class 8.8 steel screws are suitable for fastening most machinery and equipment. They are over 50% stronger than stainless steel thread-locking screws. For vibration resistance, they have a thread locker bonded to the threads.

Stainless Steel Thread-Locking Hex Head Screws

Made from 18-8 stainless steel, these screws have good chemical resistance. They have a thread locker to prevent loosening from vibration.
