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.

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 screws have excellent corrosion resistance in most environments. They have a split lock washer to create tension and resist loosening from vibration.

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

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

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.

The nonmarring brass tip is electrically conductive and harder than nylon, but soft enough to conform to most surfaces and reduce damage from metal-on-metal contact.
