Nickel Alloy Screws
When your assembly requires precision fastening in tight clearances, combined with extreme resistance to heat and corrosive chemicals, our nickel alloy screws deliver unmatched performance. We supply high-integrity machine screws, socket head cap screws, and set screws engineered for critical aerospace components, medical devices, and chemical instrumentation.
Available Alloy Grades for Screws
The reliability of a precision screw is entirely dependent on its material. We manufacture screws from premium superalloys to prevent thread shearing, head stripping, and galvanic corrosion in your most demanding applications.

Types of Nickel Alloy Screws We Supply
We offer a full spectrum of screw head profiles and drive types to accommodate your specific tooling access and clearance requirements.
Socket Head Cap Screws (SHCS)
Featuring a cylindrical head and an internal hex (Allen) drive, these are ideal for high-strength fastening in tight spaces where external wrenches cannot reach. Widely used in machinery and pump assemblies.
Countersunk / Flat Head Screws
Designed to sit flush with or below the surface of the surrounding material. Essential for aerospace aerodynamic surfaces, moving machinery parts, and medical implant assemblies.
Machine Screws
Available with pan, button, or round heads. These are fully threaded for use in tapped holes or with nuts, perfect for securing electronics housings and instrument panels in corrosive environments.
Set Screws (Grub Screws)
Headless screws fully threaded end-to-end, driven by an internal socket. Used to secure rotating parts like pulleys or gears to a high-speed shaft (e.g., Monel K-500 marine pump shafts).
