Factory Price High Performance M8 Lock Nuts-Customize is Available

FastenMetal LTD specializes in manufacturing 8mm lock nuts, strictly adhering to ISO 2320 and DIN 985 international standards, and offers cost-effective anti-loosening fastening solutions. Made from a range of high-quality materials—including carbon steel (Grade 4.8/8.8/10.9), stainless steel (304/316), and alloy steel (35CrMoA, 42CrMo)—our lock nuts feature either a nylon insert or a metal-deformation locking design to ensure excellent vibration resistance and a torque retention rate of ≥90%.

Each lock nut conforms to standard M8 thread specifications (coarse thread 1.25mm / fine thread 1.0mm pitch), with a 13mm width across flats and an adjustable height of 5–7mm. We support custom production based on customer drawings for non-standard sizes (tolerance class 6g/6H) and offer special surface treatments such as zinc plating, Dacromet, or nickel plating.

Widely used in automotive manufacturing, rail transit, and heavy machinery, our lock nuts maintain stable performance in working conditions from -30°C to 120°C. Each batch comes with a 72-hour salt spray test report and material certificate (RoHS compliant). We ensure fast delivery within 3–7 days, offer tiered pricing for bulk orders, and conduct full dimensional inspections and vibration testing (2,000 cycles without loosening), delivering reliable and cost-effective anti-loosening solutions for dynamic load applications.
