Less Hassle in Every Order
Tired of managing missing or extra washers on your assembly line?
What We Offer:Our DIN 6921 flange bolts feature an integrated bearing flange. No separate washers needed-saving your team assembly time and reducing inventory headaches.
Worried about cheap bolts rusting and ruining your project?
What We Offer:We use genuine 304 Stainless Steel (18-8) for superior corrosion resistance. It outlasts ordinary carbon steel in daily environments, ensuring a long service life without relying on easily scratched surface coatings.
Frustrated by dimension mismatches causing costly rework?
What We Offer:We don't guess sizes. Before production, our team will strictly check the required thread diameter, length, and flange dimensions against your order specs. We confirm every detail to ensure a perfect fit upon arrival.
Typical Application
Serrated
- Machine frames, motor brackets and metal housings. The serrations bite into suitable metal surfaces and help reduce loosening under vibration.
- Automotive brackets and supports where both corrosion resistance and a secure joint are needed.
- Agricultural equipment such as frames, guards and brackets exposed to outdoor conditions.
- Industrial equipment: metal panels, support brackets, machine bases and structural connections.
- Stainless steel fabrication: frames, brackets and assemblies where the mating surface can accommodate the serrated flange.
- Outdoor stainless structures: supports, frames and hardware exposed to moisture or changing weather.
Non-serrated
- Food processing equipment: frames, housings and conveyor components in suitable food production areas.
- Commercial kitchens: worktables, cabinets, cooking equipment and storage units.
- Stainless cabinets and enclosures: panels, cabinet frames, electrical enclosures and equipment housings.
- Medical and laboratory equipment: frames, instrument housings, lab furniture and support structures.
- Metal furniture and shelving: stainless furniture, racks and hardware assemblies that need a neat contact surface.
- Industrial machinery: covers, panels, mounting brackets and general mechanical parts; the flange spreads load over a wider area.
- Architectural metalwork: railings, decorative frames, support brackets and indoor fittings.
Custom Packaging&Private Label Available
Choose from bulk cartons, poly bags with branded labels, or retail-ready packaging. Minimum order quantities can be adjusted to support both small contractors and large-scale procurement needs.
