Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening.

Cleaned and double bagged in an ISO Class 5 (Class 100) clean room, these screws are ready to use on chambers and components in high-vacuum systems.

These screws are hardened to be 40% stronger than standard 316 stainless steel screws, yet they still have excellent corrosion resistance. Use them in chemical and marine applications.

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.

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.

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.

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

These metric 18-8 stainless steel screws have good chemical resistance and 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.
