Key Considerations When Bulk Purchasing Four-Pronged T-Nuts (DIN 1624)
Four-pronged T-nuts, standardized under DIN 1624, are widely used in woodworking, furniture assembly, and mechanical structures. Known for their strong pull-out resistance and secure anchoring performance, they have become a preferred fastening solution for many manufacturers. When sourcing four-pronged T-nuts in large quantities, it’s important to not only evaluate product quality and specifications but also select a reliable supplier with strong production capacity and quality control.
As a professional T-nut manufacturer, Xinchi is happy to share the key considerations and highlight Xinchi Factory’s core advantages in four-pronged T-nut production.

1. Match Specifications Precisely When Choosing Four-Pronged T-Nuts
Common thread sizes include M4, M5, M6, and M8. Selection should be based on the corresponding screw size, the hardness of the material (e.g., wood), and the end application. The number of prongs (usually 4 or 5) and prong design (sharp or flat tips) must also be chosen carefully. In automated feeding scenarios, particular attention must be paid to the nut’s flatness and collar symmetry to ensure smooth assembly.
2. Material and Surface Finish Affect the Longevity of Four-Pronged T-Nuts
Material selection plays a key role in product durability:
- Carbon Steel: Cost-effective for general wood applications.
- Stainless Steel (A2, A4): Corrosion-resistant, suitable for outdoor or high-end use.
- Surface Treatments: Options such as zinc plating (white, yellow), nickel plating, and black oxide not only enhance the appearance but also offer superior rust protection. Choose based on your specific environmental conditions.
3. Quality Control Is Central to Reliable Four-Pronged T-Nut Performance
Be sure to confirm:
- Thread precision meets ISO tolerance standards.
- Prongs are strong and durable—no bending or breakage during installation.
- Pull-out strength is tested to meet application needs.
- Batch traceability via laser marking or label coding is available.
For large-volume purchases, it is strongly recommended to request product samples for destructive testing (e.g., pull-out force) and verify with third-party inspection reports if needed.

5. Pricing Terms and Delivery Agreements Must Be Clearly Defined
Before confirming the order, be sure to clarify:
- Pricing unit (per thousand pieces or per ton), whether VAT and shipping are included.
- Payment terms, delivery schedules, and whether split shipments are supported.
- If price lock-in is available for long-term contracts to control cost fluctuations.
- Whether custom packaging, private labeling, or expedited delivery can be arranged.
6. Proper Packaging and Transportation Keep Four-Pronged T-Nuts in Prime Condition
Packaging impacts the condition of goods upon arrival. We recommend:
- Sealed plastic bags inside durable export-grade cartons, placed on pallets.
- Desiccants and rust-proof paper for sea freight shipments.
- Labels should include full specifications, quantity, batch number, and production date for easy warehousing and inventory control.
