Industrial Fasteners Manufacturer, Wholesaler, Supplier & Exporter for Automotive
High-tensile bolts, flange fasteners, and lock nuts for chassis, suspension, and drivetrain assembly, supplied to OEMs and Tier 1/2 component manufacturers.
What Automotive Buyers Need
- High-tensile grade 8.8/10.9 bolts for chassis and suspension
- Vibration-resistant lock nuts and flange fasteners
- Consistent batch-to-batch quality for automated assembly lines
- Just-in-time and container-load supply schedules
Common Challenges
Line-stopping quality variance
Inconsistent batches from unverified suppliers can halt an automated assembly line.
Long overseas lead times
Single-source overseas suppliers with unpredictable lead times put JIT schedules at risk.
How We Help
Batch-tested supply
Every batch is tested to the specified grade and documented before shipment.
Scheduled container shipments
Recurring FCL shipments scheduled against your production calendar.
Standards & Grades for Automotive Fasteners
The specifications automotive buyers most often quote. Our partner factories manufacture to the standard, grade and finish on your drawing or purchase order.
ISO 898-1 property classes 8.8, 10.9, 12.9
Mechanical property classes for carbon and alloy steel bolts; 8.8 and 10.9 cover most chassis, suspension and drivetrain joints.
ISO 898-2 nut classes 8 and 10
Nuts are matched to the bolt class so the joint fails in the bolt shank, not by thread stripping.
DIN 6921 / ISO 4162 flange bolts
Hex flange bolts with an integral washer face spread clamp load on thin sections and speed up automated assembly.
DIN 985 / ISO 7042 prevailing-torque nuts
Nylon-insert and all-metal lock nuts that resist loosening under vibration.
Materials & Coatings
Alloy steel, quenched & tempered
Boron and Cr-Mo steels heat treated to reach class 10.9 and 12.9 hardness and tensile strength.
Zinc flake and zinc-nickel coatings
Thin, non-electrolytic coatings with high salt-spray resistance and low hydrogen-embrittlement risk for high-strength bolts.
Phosphate & oil / black oxide
Economical finishes for fasteners used inside assemblies where appearance and heavy corrosion protection matter less.
