Nickel Alloy Fasteners: Essential Components for Specialized Applications
Types of Nickel Alloy Fasteners
Nickel alloy fasteners come in a variety of forms to suit different application needs:
Bolts: Fasteners with external threads that are used to secure two or more components together. Common types include:
Stud Bolts: Threaded rods used with nuts to fasten materials.
Hex Head Bolts: Bolts with a hexagonal head, typically used with wrenches.
Socket Hexagon Head Screws: Screws driven by a hexagonal socket tool.
Anchor Bolts: Used to attach objects to concrete or masonry.
U-Bolts: Shaped like a “U,” ideal for securing pipes or rods.
J-Bolts: Resembling the letter “J,” they provide secure attachment to surfaces.
Mushroom Head Square Neck Bolts: Bolts with a square neck to prevent rotation.
T-Head Bolts: With a T-shaped head, commonly used in machinery.
Wing Screws: Screws with “wings” that allow manual tightening without tools.
Sizes of Nickel Alloy Fasteners
Nickel alloy fasteners are available in a broad range of sizes to accommodate a variety of applications:
Metric Sizes: M3 – M56
Inch Sizes: 3/6 Inch to 2 Inch
This wide range ensures that fasteners can be tailored to meet the specific requirements of a given project or industry.
