Import Countersunk Head Insert Nuts/Rivet Nuts — Buy in Bulk from Supplier in China

The product offered by Guangzhou Yinglai Hardware Product Co., Ltd. is a countersunk head insert nut, also referred to as a rivet nut, available with flat, standard countersunk and small countersunk head styles. The catalogue lists column types such as park rod, groove and hexagonal (semi‑hexagonal) and mentions material choices of carbon steel, aluminum and stainless steel. Size options include metric threads M3, M4, M5, M6, M8, M10 and M12 as well as imperial threads 6‑32, 8‑32, 10‑32, 1/4‑20, 5/16‑18, 3/8‑16 and 1/2‑13. These dimensions match common fastener standards used in machinery and construction applications.

The nuts are supplied in a range of materials allowing buyers to select carbon steel for general use, aluminum for lightweight needs or stainless steel for corrosion‑resistant environments. In the fastener industry, a typical carbon‑steel insert nut is heat‑treated to achieve a tensile strength around 400 MPa and may receive a zinc plating for basic corrosion protection. The small countersunk head variant is frequently chosen where a low profile is required, while the larger countersunk head provides greater bearing area for heavy‑duty assemblies.

Typical users include equipment manufacturers, automotive assemblers and construction firms that need reliable threaded inserts for thin sheet metal. Procurement teams should confirm the exact material grade, required head size and thread standard before placing an order. Trade terms such as minimum order quantity, incoterms and payment method are not disclosed in the listing and should be clarified directly with the supplier.
