Custom Fasteners

Custom fasteners are specialized hardware components manufactured to meet specific requirements, such as unique dimensions, thread patterns, or materials. They can be designed to meet strength, durability, or corrosion resistance specification and can often improve the performance and longevity of the end product.

They are extremely valuable in the manufacturing industry as they provide a solution for unique or challenging projects where standard fasteners are unsuitable. Furthermore, they reduce assembly time and costs, as they are designed to fit perfectly into the intended application.

Custom fasteners can also increase safety as they can be designed to meet safety standards and regulations in the specific industry. This can be especially important for the aerospace, defense, and medical equipment industries.

Our Process

At Chicago Nut & Bolt, we supply custom fasteners and package them according to the requested size, weight, container, and labeling requirements. Thus, we can help facilitate integration with your inventory and handling systems.

Every step of our process — from special head marking to custom plating — adheres to strict controls to ensure product quality and integrity. As a result, we deliver high-quality products at all times.

Chicago Nut & Bolt is EDI-capable, providing a fully integrated, dock-to-stock supply! Once we receive your fax or email containing the specification of fasteners, pricing and delivery details are dispatched within minutes. The custom fastener deliveries can be made according to your scheduling or laydown needs — be it 24 hours or seven to ten days. We can also warehouse the parts, then ship them to your location when requested.

Utilizing our massive inventory of blanks, we supply fasteners inclusive of custom bolts, nuts, and screws. We also work with sizes from ¼ in. to 4 in. in diameter and lengths up to 72 in.

Materials

Chicago Nut & Bolt is equipped and skilled to provide for our customer’s needs when they need it. We provide aluminum, copper, brass, carbon steel, alloy steel, stainless steel, and A286 materials for customized fasteners. We can also alter the oversized and undersized heads and the length, width, threads, and tolerances.

Applications

Chicago Nut & Bolt has produced and supplied specialized fasteners for various sectors. These include agriculture equipment, military and defense, marine, railroad/locomotive, mining, construction equipment, and engine manufacturing.

Our company supports all processes to make and stock your custom-engineered fasteners by supplying components, including multi-blow/die cold-formed specialties and parts with secondary operations.

Fastener Machining Capabilities

With a focus on precision and efficiency, we have the tools and expertise to deliver top-quality results. Here are some of our key machining services:

CNC Machining (Milling/Turning)

Tight tolerance machining per blueprint specifications is essential for achieving high precision in parts and components. Our facility uses state-of-the-art CNC milling and turning machines to produce high-quality parts according to our client’s specifications. We also pride ourselves on delivering exceptional quality and meeting the tightest tolerances.

Drilling

We can provide precise, accurate drilling for fasteners of various sizes and materials. Our drilling services can accommodate high-volume production runs and tight tolerance requirements, ensuring that each fastener meets the exact specifications for your application.

Knurling

High-quality custom fastener manufacturers use specialized knurling machines that can work on different shapes and sizes. It makes it possible to create knurled patterns on even the most complex components.

Tapping

Tapping is a machining process used in fastener-making to create internal screw threads in a hole drilled, reamed, or bored.

Thread Grinding

Thread grinding produces precise, high-quality threads on fasteners. The process involves using a specialized grinding machine to cut and shape the thread form on a fastener’s surface.

Thread Rolling

This technique uses hardened dies to press material into a thread form, resulting in a fastener with a precise, uniform thread pattern. Unlike thread cutting or grinding, thread rolling does not remove any material, making it a more efficient and cost-effective method of producing threaded fasteners.
