The Directly Factory Supply All Kinds Of Lock Nut is offered by Hebei Fengmai Metal Products Co. Ltd as a complete range of lock nuts covering metric sizes from M5 to M48. Materials include carbon steel grades Q235B, 10B21, 35K and 45#, as well as stainless‑steel grades 304, 316 and 316L.

The product conforms to standards DIN 982, ISO 7043 and DIN 980V, providing a recognised basis for dimensional accuracy.

In the fastener market, carbon‑steel lock nuts of grade 8 typically exhibit a tensile strength around 800 MPa, while stainless‑steel variants offer superior corrosion resistance in humid environments. The typical thread pitch follows the ISO 68 metric series, ensuring compatibility with standard bolts. Typical torque resistance for a grade 8 M12 lock nut is approximately 150 Nm, a figure that helps designers select appropriate fastening torque. These industry norms complement the supplier’s listed specifications and aid in engineering calculations.

Lock nuts from Fengmai are suited to automotive assembly lines, machinery manufacturers and infrastructure projects that require vibration‑resistant fastening. The listing states a payment term of 30 % deposit and 70 % balance before loading, but does not disclose minimum order quantities or lead‑time, so those details must be confirmed directly. Buyers should also ask whether OEM customisation, such as logo imprinting or special packaging, is available. Establishing clear logistics and quality expectations early will streamline the import process.

Hebei Fengmai Metal Products Co. Ltd is situated north of Weizhuang Village, Liuying Town, Yongnian District, Handan City, Hebei Province, China. The supplier carries a harbour trust tier, indicating a basic verification level, and its response rate is recorded as 0 % with no average response time available.

The company markets a broad assortment of lock nuts, including nylon, metal, spring‑hex, all‑metal and torque‑lock variants. OEM production is accepted, although the listing does not detail the extent of customisation capabilities or production capacity, so those points should be clarified with the supplier during negotiations.
