Fastening Nuts & Nut Assemblies


Nut fasteners secure bolts and other threaded fasteners to various materials and create firm connections. They are some of the most versatile fasteners available and are used across virtually all assemblies in industrial and commercial applications. Nuts are used with bolts and threaded rods to establish secure joints and connections. Using washers with nuts and bolts can further increase the strength of these connections. Types of nut fasteners range from standard hex nuts to locking nuts and more. Trio Fasteners proudly offers an extensive selection of nuts in various sizes, materials, and styles for use in a variety of applications.

Types of Nut Fasteners

Trio Fasteners supplies high-performance nut fasteners in various options and assemblies. Read below to learn more about our selection of nuts.

Coupling Nuts

Coupling nuts, or rod couplings, are long nut fasteners with extended internal threading. These nuts are designed specifically for joining or “coupling” two threaded bolts or rods into one joint connection. Coupling nuts can be threaded onto externally threaded rods of the same dimensions with a wrench or socket set for easy installation.

Finished Hex Nuts

Finished hex nuts are among the most popular nut fasteners and are used for general-purpose projects and connections. They feature a standard hexagonal shape with a low body and are threaded onto corresponding bolts or threaded rods to form secure connections. Finished hex nuts are used for industrial and commercial applications for a vast assortment of projects.

Heavy Hex Nuts

Heavy hex nuts are a strong, reinforced version of finished hex nuts, specially designed for heavy-duty or high-strength applications. They have a thicker build with a wider surface, which increases load-bearing strength. These nuts are common for machinery or industrial applications across many trades.

Locking Nuts

Locking nuts are created with excellent vibration resistance properties and high-temperature tolerances. Internal nylon inserts can increase motion resistance, helping prevent loosening in high-stress environments. Locking nuts are used for extra security in turbulent applications.

Materials for Nuts

Trio Fasteners offers nut fasteners in a range of materials to cater to your unique project needs.

Stainless Steel

Stainless steel (SS) is known for its excellent corrosion resistance, allowing for use in a wide range of applications. Nut fasteners from Trio Fasteners are available in 316 SS and 18-8 SS. These grades are suitable for internal and external use, blending corrosion resistance with strength to ensure secure nut connections.

Steel

Trio Fasteners supplies steel nut fasteners in Grade 2, Grade 5, and Grade 8 alloys. Grade 2 steel is a low-carbon alloy and, as such, is used for projects requiring minimal strength or hold. Grade 5 and Grade 8 alloys are medium-carbon alloys, which allow these nuts to be used in more demanding environments for industrial work. Steel nut fasteners are cost-effective solutions for stable and secure connections.

Brass

Brass nut fasteners are most notable for their golden appearance and aesthetic finish. Primarily created from a blend of zinc and copper, brass provides corrosion resistance by forming an oxide layer and preventing rust. Brass nuts are also malleable and are used for friction applications or low-stress projects.

Nut Fastener Finishes

In addition to the properties and benefits of a nut’s material, its finish can offer further advantages, such as increased durability, reinforced corrosion resistance, or higher temperature tolerances. Finishes can include:
  • Zinc
  • Plain
  • Hot-Dip Galvanizing (HDG)
