When a critical assembly fails, the culprit is often something small—a stripped thread, a corroded nut, or a fastener that simply couldn’t handle the load. At Jiesheng Hardware, we see this firsthand. That’s why we’ve built our reputation on producing custom-machined brass nuts and precision stainless steel nuts that meet exacting specifications for Industries ranging from automotive to medical devices.
With over 20 years of experience in precision metal parts manufacturing and ISO 9001 and IATF 16949 certifications, we don’t just make nuts—we engineer fastening solutions

Brass vs. Stainless Steel: Why Material Choice Matters for Custom Nuts
The material you choose for your custom precision nuts directly impacts performance, lifespan, and cost. Here’s how brass and stainless steel compare.
Brass Precision Nuts: Corrosion Resistance with a Touch of Machinability
Brass is a copper-zinc alloy prized for its excellent machinability, natural corrosion resistance, and aesthetic appeal. Custom brass nuts are widely used in plumbing, Electrical connectors, pneumatic fittings, and decorative hardware.
Advantages of brass for custom nuts:
Superior machinability: Brass cuts cleanly and quickly, making it ideal for complex, custom turned nuts with fine threads or knurled surfaces.
Corrosion resistance: Brass naturally resists rust and tarnishing, performing well in moist or mildly corrosive environments.
Low friction: Brass nuts resist galling and seizing, especially when paired with stainless steel bolts.
Non-sparking and non-magnetic: Essential for applications in explosive environments or sensitive electronic equipment.
At Jiesheng, we machine brass nuts from high-quality materials like C360 free-cutting brass, ensuring dimensional stability and a smooth surface finish that meets your exact print.
Stainless Steel Precision Nuts: Strength and Durability for Demanding Applications
When the application demands higher strength, temperature resistance, or superior corrosion protection, stainless steel nuts are the go-to choice. We work with austenitic grades like 303, 304, and 316 stainless steel, as well as martensitic and precipitation-hardening grades for specialised requirements.
Advantages of stainless steel for custom nuts:
High tensile strength: Stainless steel nuts handle high loads and extreme conditions without deforming.
Outstanding corrosion resistance: 316 stainless steel excels in marine, chemical, and outdoor environments.
Temperature resistance: Stainless maintains mechanical properties across a wide temperature range.
Durability: Resists wear, fatigue, and galling, ensuring long service life in dynamic assemblies.
Our custom stainless steel nuts are 100% inspected before shipment, with optional surface treatments like passivation, zinc plating, or nickel plating to enhance performance and appearance.
Customisation Options: Your Design, Our Precision
At Jiesheng Hardware, we specialise in custom nuts made to your drawings. Whether you need a standard hex nut in a non-standard size or a complex CNC-machined nut with off-centre holes, special threads, or knurling, we deliver.
Our custom nut manufacturing Capabilities include:
Materials: Brass, stainless steel, carbon steel, alloy steel, copper, titanium, and more.
Thread types: Metric (ISO), imperial (UNF/UNC), pipe threads (NPT/BSP), left-hand threads, and custom pitches.
Head styles: Hex, square, slotted, castle, cap, flange, wing, knurled thumb nuts, and weld nuts.
Secondary operations: Drilling, tapping, slotting, knurling, heat treatment, and surface finishing (zinc plating, nickel plating, anodising, passivation, Dacromet, and more).
Production volumes: From prototypes and small batches to high-volume production runs—our production capacity exceeds 5,000,000 pieces per month.
Need a custom machined brass nut with a knurled grip for hand-tightening? Or a precision stainless steel nut with a nylon patch for vibration resistance? We’ve got you covered.
Quality Assurance: Every Nut Inspected, Every Standard Met
Precision doesn’t happen by accident. Our manufacturing process is backed by ISO 9001 and IATF 16949 certifications, ensuring that every custom nut meets rigorous quality standards.
Our quality control process includes:
Incoming material inspection: We verify chemical composition and mechanical properties.
In-process inspection: Dimensional checks at every stage using calibrated gauges, optical comparators, and CMMs.
Final inspection: 100% dimensional and thread inspection before packaging—we follow MIL-STD-105E AQL=0.65 standards to ensure defect-free parts.
Testing: Torque testing, hardness testing, and salt spray testing for corrosion resistance as needed.
This commitment to quality is why Jiesheng is trusted by clients in automotive, aerospace, medical, electronics, heavy equipment, and sim racing industries.
