Better Fastener Industry Co., Ltd. is one of China's Custom Hexagon Nuts Manufacturers, producing standard and custom hex nuts in carbon steel, stainless steel and alloy steel. Our range covers DIN 934, ISO 4032, ANSI B18.2.2 and equivalent specifications, supplied with zinc plating, hot-dip galvanizing or blackening finishes for construction, machinery, automotive and distribution programs.
Hexagon Nuts We Manufacture
Hexagon nuts are the standard companion fastener to bolts across engineering and construction. We produce them with precision-tapped internal threads for consistent engagement and predictable preload when torqued to specification. Standard, thin and thick profiles are available to suit different joint thicknesses and load requirements.
Our Hexagon Nuts range includes the following verified standards and variants:
- DIN 934:1987 — coarse and fine thread metric hex nut, the general-purpose European standard.
- ASME/ANSI B18.2.2 (T1-1 Hex):2010 — inch-series hexagon nut for North American projects.
- DIN 6915:1999 — high-strength heavy hexagon nut for structural steel bolting.
- ASME/ANSI B18.2.2 (T6):2010 — heavy hexagon nut for high-load joints.
- DIN 936:1985 and DIN 439 (-1):1987 — thin hexagon nut and thin unchamfered nut for confined spaces.
- ASME/ANSI B18.2.2 (T9):2010 and ASME B18.2.2 (T3-HFJ):2010 — heavy hex jam nut and thin hexagon jam nut for locking applications.
- DIN 971 (-1):1987 and DIN EN 28675:1992 — fine thread metric nuts for precision assemblies.
- DIN 6334 — hexagon coupling nut for joining threaded rods.
- DIN 74305-2:1994 — pipe connection hexagon nut for fluid and pneumatic lines.
Materials and Finishes
We manufacture hexagon nuts in carbon steel, stainless steel and alloy steel. Material selection is matched to the bolt grade, corrosion exposure and temperature range of the joint. Standard finishes include zinc plating, hot-dip galvanizing and blackening.
| Material | Typical Grade | Finish Options | Application Fit |
|---|---|---|---|
| Carbon steel | Class 8, Class 10 | Zinc plating, hot-dip galvanizing, blackening | General construction, machinery, distribution |
| Alloy steel | Class 10, Class 12 | Zinc plating, blackening | Structural steel, heavy equipment, high-load joints |
| Stainless steel | A2, A4 | Passivated | Marine, chemical, food processing, outdoor exposure |
How to Specify Hexagon Nuts for Your Project
To prepare an accurate proposal, we need the following information. This is the same data our engineering team uses to confirm feasibility and pricing.
- Standard and thread: DIN, ISO, ANSI or equivalent; metric or inch; coarse or fine pitch.
- Size: nominal thread diameter (M3–M64 or equivalent inch sizes).
- Grade: property class or material grade required for the joint.
- Profile: standard, thin, heavy or jam nut configuration.
- Finish: zinc plating, hot-dip galvanizing, blackening or passivation.
- Quantity: annual volume or per-order batch size.
- Packaging: bulk, retail kit, blister pack or custom carton.
- Documentation: mill certificates, dimensional reports or third-party inspection requirements.
Quality Control and Acceptance
Our factory operates an in-house laboratory equipped with a spectrometer, CMM, X-ray flaw detector and other testing equipment. We monitor chemical composition, mechanical properties, non-destructive testing and geometric dimensions. Inspections are conducted after each process, and 100% of finished products undergo final inspection in accordance with customer requirements and international standards.
For hexagon nuts, critical inspection points include thread gauge verification, across-flats and across-corners dimensions, nut height, proof load and hardness. We can supply inspection certificates and dimensional reports with each shipment.
Related Fasteners from Our Range
Hexagon nuts are used with matching bolts and studs. We also manufacture Hexagon Head Bolts, Double End Studs and Hexagon Flange Nuts to complete the joint. This allows us to supply matched fastener sets from a single production and quality system.
Packaging and Delivery
We offer flexible packaging solutions including retail kits, blister packs, custom boxes and export cartons. Our location is within a 2-hour drive of Shanghai and Ningbo ports, which supports efficient sea freight. For urgent requirements, air freight can be arranged via Ningbo or Shanghai airports.
Frequently Asked Questions
What standards do your hexagon nuts conform to?
We produce to DIN 934, ISO 4032, ANSI B18.2.2 and equivalent specifications. Our range includes DIN 6915, DIN 936, DIN 439, DIN 971, DIN EN 28675, DIN 6334, DIN 74305-2 and ASME/ANSI B18.2.2 variants.
Can you supply hexagon nuts in stainless steel?
Yes. We manufacture hexagon nuts in A2 and A4 stainless steel as well as carbon steel and alloy steel. Stainless steel nuts are passivated for corrosion resistance.
Do you support custom hexagon nut production?
Customized production is our core business. As custom hexagon nuts manufacturers, we develop and produce hexagon nuts based on drawings or samples, including non-standard dimensions, special thread pitches and specific material grades.
What is your production capacity for hexagon nuts?
Our factory operates 12 energy-efficient production lines with an annual capacity exceeding 20,000 tons. This supports both large-volume orders and small to medium batch purchases.
How do you ensure hexagon nut quality?
We implement total quality management throughout production. Inspections are conducted after each process, and 100% of finished products undergo final inspection. Our laboratory uses a spectrometer, CMM and X-ray flaw detector to verify chemical composition, mechanical properties and dimensions.
What information do you need to quote hexagon nuts?
Please provide the standard, thread size, grade, profile, finish, quantity and packaging requirements. If you have drawings or samples, we can work from those directly.
