Hex head machine screws are miniature, flexible fasteners. They have a hex shaped head and connect with a hex nut. If manufactured using exotic alloys such as Inconel, Monel, Hastelloy, or other high-performance materials, hex head machine screws offer excellent resistance to extreme conditions. Their chemical & mechanical properties make them key for industries operating in demanding environments. These industries include aerospace, marine, chemical processing, and power generation. In chemical plants & applications, these screws can endure exposure to aggressive acids & solvents. In aerospace, they maintain integrity under extreme heat & pressure. At Nickel-Systems Inc., we specialize in delivering superior hex head machine screws that meet stringent requirements. Whether you need a screw that meets ASME, ASTM, ISO or another standard, our team is ready to provide you with the right machine screw at the right price.

Nickel Systems stocks hex head machine screws in various head types & sizes for your next project. Use our specifications and technical data below to select your specific screw. If you don’t see your specific size, please contact us. We can supply custom requests.
For common sizes, hex head machine screws are typically produced in fractional length increments of 1/16 in. for screws up to 5/8 in. long, 1/8 in. for screws over 5/8 in. through 1-1/2 in. long, and 1/4 in. for screws over 1-1/2 in. long.
A machine screw is general type of screw which may be described as a threaded fastener with a uniform diameter and threads. These are designed to mate with a tapped hole or nut. Unlike wood screws, which are tapered and rely on gripping into softer materials, machine screws depend on precise threading for their holding strength. They are often used in metalworking, electrical assemblies, and machinery.

What are Hex Head Machine Screws
A hex head machine screw is a threaded fastener with a hexagonal-shaped head. Its threads run the entire length of its body. It can come in both coarse & fine threads. It can have a standard, large or indented head.
Hex Head Machine screws may also be referred to as:
Benefits: Resistance to corrosion including saltwater & hydrogen sulfide
A Nitronic 60 Hex Head Machine Screw with a washer face, often used in pump & valve components (Washer faces have tighter tolerances and allow for a more secure connection between the fastener and its connecting component)
Marine
Applications: Shipbuilding, underwater structures including docks, & marine engines
Benefits: Biocompatibility & resistance to sterilization processes
Tips for Purchasing
Choose the right dimensioning specification: Include the (1) the nominal diameter, (2) the thread type, & (3) the desired length. See our dimensions above.
Choose the right material: Choose the correct material from our material’s list Nickel System’s Materials.
Consider if you need additional protection by asking about coatings.
Confirm if your part or drawing prints have a specific specifications: ASTM, ISO, DIN or other specifications.
Consider related parts if needed: Hex head machine screws are often ordered with machine screw hex nuts, washers, or lock washers. Check out our other related products below a sample products gallery.
