Nuts
Nylon Insert Lock Nuts Wholesaler
We wholesale nylon insert lock nuts in bulk to distributors, retailers, and hardware stockists, with volume pricing and container-load (FCL/LCL) shipping options.
As a wholesaler, we hold ready stock across common sizes and grades and supply distributors, retailers, and hardware stockists at volume pricing — the buyer relationship here is about consistent supply and competitive per-unit cost at container-load quantities.
Wholesale buyers typically care more about consistent lead time and pricing stability across repeat orders than about a single one-off transaction, which is why we hold ready stock specifically for the sizes and grades that move fastest, rather than manufacturing every order from scratch.
Nylon insert lock nuts work by interference, not friction — the bolt thread has to physically deform the nylon collar as it passes through, which is exactly why a nylon lock nut should never be reused after removal. Once the nylon has taken the shape of the thread, it no longer grips a fresh bolt with the same prevailing torque, even though the nut looks completely undamaged.

Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 1-1.4 million pieces of nylon insert lock nuts in common sizes (M10-M12). Exact quantity depends on size 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.

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.
