About Socket Head Screws

Alloy Steel Wire-Lockable 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 more than twice as strong as stainless steel wire-lockable screws. These resist vibration better than any other socket head screw.

Stainless Steel Wire-Lockable Socket Head Screws

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.

Vented Socket Head Screws

Drilled through the head and shaft, these screws vent fluid and gases trapped below the screw, making them good for vacuum applications.

High-Vacuum Cleaned-and-Bagged
Vented Socket Head Screws

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

Vented Flat Head Screws

These screws are drilled through the shaft to vent fluids and gases trapped under the screw.

Metric Vented Flat Head Screws

To vent fluids and gases trapped under the screw, these metric screws are drilled through the shaft.

Metric Vented Button Head Screws

To vent fluid and gas trapped under the screw, these metric screws are drilled through the shaft. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.
