Custom Fasteners - Chicago Nut & Bolt.

Fasteners ensure safety in industrial projects, securing heavy machinery and structures to prevent accidents and injuries and promoting stability and efficiency in industrial applications. They are designed to meet precise requirements and address the unique demands of commercial environments to guarantee optimal suitability and effectiveness.

Custom fasteners range from standard screws, nuts, and bolts to specialized variants, all engineered to improve durability in various operations. At Chicago Nut & Bolt, we offer a variety of fasteners tailored to diverse applications. Our expertise assures that each fastener exceeds client expectations through precise engineering and quality commitment.

Types of Custom Fasteners

Here are the different customized fasteners that elevate performance and durability across industries:

Screws

Screws are essential for diverse applications. For instance, wood screws are perfect for joining wood, and sheet metal screws are ideal for metal fastening. Meanwhile, machine screws thicker and robust find their niche in machinery and appliances, often paired with nuts and bolts to reinforce connections. They also improve grip strength and resistance to corrosion or wear.

Nuts and Bolts

Nuts and bolts are essential for secure structural connections. They offer versatility, from carriage bolts with domed heads to flange bolts distributing loads evenly. Custom sizing and materials optimize strength and compatibility, while specialized heads provide added security. Washers reduce friction and prevent loosening, with options to improve resistance to corrosion, moisture, and wear for secure connections.

Rivets

Rivets are the go-to solution for permanent joints, particularly in high-strength applications demanding utmost reliability. Their exceptional strength surpasses other fasteners, making them indispensable for securing metal sheets and plates. Custom rivet sizing and materials also enhance durability for crucial connections in construction, automotive, and aerospace.

Bushings

Bushings alter bore sizes to provide load-bearing support or facilitate rotational movement. Each type fulfills functions essential in machinery applications, from dowel bushings guaranteeing precise alignment to bearings reducing friction. Custom materials and designs refine their load-bearing capacity, minimize friction, and enhance durability.

Commonly Used Materials for Custom Fasteners

Selecting materials with superior properties improves component longevity. Listed below are the common materials used in custom fastener fabrication:

Aluminum: Known for its lightweight nature and corrosion resistance, aluminum is often used in aerospace and automotive industries where weight savings are critical.
Brass and bronze: Brass (an alloy of copper and zinc) and bronze (an alloy of copper and tin) are valued for their corrosion resistance and visual appeal. They are commonly used in decorative applications as well as in marine settings.
Stainless steel: This is valued for its strength, durability, and corrosion resistance. It is versatile and extensively used in various industries, including construction, automotive, and manufacturing.
Titanium: This boasts an exceptional strength-to-weight ratio, corrosion resistance, and high-temperature resistance. It is commonly used in aerospace, medical, and marine applications where strength-to-weight ratio and resistance to harsh environments are crucial.
Ceramics: These provide excellent heat corrosion resistance and electrical insulation properties. They are ideal for extreme environments like high-temperature or corrosive settings where other materials may not perform well.

Coatings and Treatments

Fastener durability and resilience are enhanced by applying various coatings and treatments. The following are some common options used in the industry:

Zinc plating: It is a widely used method that involves applying zinc to fastener surfaces. This provides excellent corrosion resistance.
Galvanization: This process involves immersing fasteners in molten zinc, forming a protective layer that shields against corrosion and environmental damage.
Anodizing: This electrochemical process creates a durable oxide layer on fastener surfaces, enhancing resistance to corrosion and wear.
Passivation: This chemical treatment removes free iron from the surface of stainless steel fasteners, improving their corrosion resistance.
