As a professional custom nut manufacturer, we specialize in producing non-standard nuts, special nuts, CNC-machined nuts, and large-size industrial nuts according to customer drawings, samples, and technical requirements.
Whether you need unique shapes, customized threading, special materials, or precision tolerances, we deliver fast, accurate, and cost-effective solutions for global industries.
A custom nut is a specially manufactured nut that does not follow standard specifications such as DIN, ANSI, ISO, JIS, or BS. These nuts are designed for unique applications where standard nuts cannot meet strength, size, or structural requirements.
Situations that Require Custom Nuts
Special thread pitch or profile
Unique outer shape (square, round, wing, stepped, slotted)
Large diameters (M30–M200 / 1"–8")
High-strength or corrosion-resistant material
Special torque or load requirements
Custom coatings for harsh environments
We produce custom nuts using a wide range of materials:
Carbon steel: Grade 4.8 / 8.8 / 10.9 / 12.9
Stainless steel: SS304, SS316, SS316L
Alloy steel: 35CrMo, 42CrMo, SCM435
Brass & copper alloys
Aluminum
Titanium (Ti Grade 2 / Grade 5)
Special materials on request
Cold forging for high strength & mass production
Hot forging for large-size or heavy-duty nuts
CNC machining for high precision and small batches
Thread rolling & tapping (metric, UNC, UNF, BSW, custom threads)
Heat treatment for enhanced hardness & tensile strength
Zinc plated
Hot-dip galvanized (HDG)
Black oxide
Dacromet / Geomet
Nickel plated
Powder coating
Custom anti-corrosion coating
Available in carbon steel, stainless steel, and alloy steel, suitable for machinery and construction applications.
Ideal for channels, frames, and machinery requiring large bearing surfaces.
For vibration-resistant or safety-critical applications.
With integrated flange for improved load distribution.
Designed for tools-free tightening and frequent adjustments.
Produced using hot forging or CNC turning for heavy equipment, mining, or oil & gas.
We offer nuts in a variety of sizes, materials, and finishes. Our products are fully customizable to meet specific project requirements, such as galvanized coatings for corrosion resistance or black oxide finishes for enhanced durability. As your trusted custom nut provider, we make sure to deliver exactly what your projects require.
Our custom nuts are produced using top-quality carbon steel, stainless steel, and alloy steel. This variety allows us to supply products that meet high-load and high-temperature performance demands, suitable for a wide range of industrial and commercial uses.
The design of custom nuts offers better surface contact compared to traditional fasteners, allowing for superior load distribution and torque control. These advantages make our nuts the preferred choice for industries that prioritize reliable fastening.
Our products are ideal for heavy machinery, construction frameworks, railway systems, and woodworking. By offering high-strength solutions, we have established ourselves as a key supplier for critical industries that demand durability and stability.
Bentley is committed to being a reliable custom nut supplier by ensuring that each product undergoes strict quality assurance procedures. Our nuts comply with major industry standards, including ISO, DIN, and ANSI, ensuring that our custom nuts meet global expectations for strength, durability, and performance.
Whether you are seeking high-quality custom nuts for construction, heavy machinery, or specialized industrial use, Bentley Technology is your go-to partner.
