Flange Bolts & Flange Nuts Manufacturer, Wholesaler, Supplier & Exporter to South Africa
Flange bolts and nuts have an integrated washer face that spreads clamping load and, in serrated versions, bites into the mating surface to resist loosening — eliminating a separate washer. We manufacture and export these to DIN 6921 / DIN 6923. South Africa's mining, construction, and heavy machinery sectors depend on a steady supply of certified structural and general-purpose fasteners. We ship into the Port of Durban, South Africa's busiest container port, and the Port of Cape Town.

Duty and tax rates change and transit depends on carrier, routing, and port congestion, so figures marked indicative are confirmed against your product and destination port when we quote. Your customs broker should verify final landed cost.
Flange bolts and nuts exist to solve a simple problem more cheaply than a washer does: distributing clamping force over a wider bearing surface without adding a separate part to the bill of materials. That's a meaningful saving at automotive and agricultural-machinery production volumes, where every eliminated component also removes a step from the assembly line.
About Flange Bolts & Flange Nuts
Serrated and non-serrated flange bolts and flange nuts to DIN 6921 and DIN 6923 — manufactured and exported for automotive and machinery assembly.

- • SABS-referenced or equivalent DIN/ISO/ASTM standards are commonly requested by South African industrial buyers.
- • Mining and heavy machinery buyers often need custom precision components alongside standard catalog fasteners.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 500,000-700,000 sets of flange bolts/nuts in common sizes (M8-M10). Exact quantity depends on size and grade and is confirmed at quote time.
You don't need a full container to order. Hurain Engitech & Trade — the group Global Fasteners Exports operates under — regularly ships smaller, partial-container (LCL) orders of just a few pallets or boxes for buyers who don't yet need FCL volume, consolidated with other cargo to keep freight cost reasonable.
Where South Africa Buyers Use Flange Bolts & Flange Nuts
Automotive engine and chassis assembly
High-volume fastening where the integrated flange replaces a separate washer.
Agricultural machinery
Vibration-prone equipment joints benefiting from the serrated flange's locking action.
General machinery reducing part count
Assemblies where eliminating a separate washer simplifies both the bill of materials and the assembly line.
Common Mistakes Buyers Make
Expecting serration locking on a hardened surface
Serrations need to bite into a softer mating surface — they add little locking benefit against hardened or highly finished steel.
Substituting a standard bolt plus washer without checking clamp area
A flange bolt's integrated bearing surface is engineered to a specific diameter — a standard bolt and generic washer may not match it.
Reusing serrated flange fasteners after removal
The serrations can dull or flatten after one torque cycle, reducing locking performance on reinstallation.
Key Terms
- Serrated flange
- A flange bolt or nut head with radial grooves that bite into the mating surface for added locking resistance.
- Integrated washer face
- The flange itself, which spreads clamping load the way a separate washer would.
- Non-serrated flange fastener
- A flange bolt or nut without locking serrations, used where a smooth bearing surface is required against a finished or hardened joint.
How Ordering Works
- 1
Send your requirement
Product, grade/standard, quantity, and your preferred Incoterm (FOB/CIF/CFR).
- 2
Receive a quote
We confirm price, lead time, and MOQ based on ready stock or manufacturing time.
- 3
Sample & confirm (optional)
For new buyers, we can arrange samples before the full order is confirmed.

HS Code & Customs Classification
Most fasteners fall under HS Chapter 73 (articles of iron or steel) or Chapter 74/76 for brass and aluminum items — the exact 8-10 digit subheading depends on the specific product and material. We include the HS code on the commercial invoice; confirm the applicable import duty with your customs broker, since rates vary by country and trade agreement.
