In industrial production, construction, and daily equipment assembly, standard fasteners often fail to meet specific size, strength, or environmental requirements. Custom fasteners—including nuts, screws, and bolts—fill this gap by offering tailored designs, ensuring optimal performance and durability in diverse scenarios. These components are not just "small parts"; they are critical to the stability and safety of the entire structure or device they secure.
Custom fasteners are categorized by their functions, with three core types dominating most applications:
Typically paired with screws or bolts, nuts feature internal threads to lock components in place. Custom nuts can be designed with unique shapes (hexagonal, square) or thicknesses to fit limited spaces.
Screws
Equipped with external threads and a head (Phillips, flat), screws are used to fasten materials by tapping into pre-drilled holes.
Longer than most screws, bolts require a nut to secure heavy loads. Custom bolts are often engineered for high-tensile strength, making them ideal for structural projects.
The choice of material directly impacts a fastener’s lifespan and performance. Two materials can be choosed.
Carbon Steel
Cost-effective and easy to machine, carbon material offer good tensile strength. However, they are prone to rust, so they are best suited for indoor, dry environments (furniture assembly).
Stainless Steel
Composed of steel, chromium, and nickel, stainless steel resists corrosion, oxidation. It is the preferred choice for outdoor, humid or high-humidity environments. Although it is more expensive than carbon steel, its durability proves that the cost for long-term use is reasonable.
Custom fasteners are indispensable across multiple industries, thanks to their adaptability:
Construction
Used in steel frames, bridges, and concrete structures (stainless steel bolts for weather resistance).
Automotive
Securing engine parts, chassis, and interiors (carbon screws for low-stress areas, stainless steel for undercarriage components).
Electronics
Small-scale custom screws for smartphones, laptops, and circuit boards (precision-machined to avoid damaging delicate parts).
Medical
Stainless steel fasteners for surgical tools and implants (non-toxic and corrosion-resistant to meet hygiene standards).
Marine
Heavy-duty stainless steel bolts and nuts for ships and offshore platforms (resistant to saltwater erosion).
The production of custom fasteners follows a standardized, precision-focused workflow, outlined in the table below:
Generic fasteners often force compromises in design or performance. Custom fasteners solve this by:
Meet the special size or strength requirements that standard components cannot fulfill.
Reduce costs.
Enhance safety.
