DIN980V Product Core Advantages
Integrated One-piece Structure, Zero Falling Risk
DIN980V adopts one-piece integrated forming technology, different from DIN980M two-piece inlaid structure without independent lock chips and falling hidden dangers. It generates preset locking torque through thread plastic extrusion deformation, featuring tight engagement and uniform stress. It maintains stable fastening performance without loosening under continuous vibration and alternating load, with far higher structural stability than ordinary lock nuts.
The full-metal rigid structure eliminates vulnerable materials such as nylon, completely solving the failure problems of nylon lock nuts caused by high-temperature melting, low-temperature cracking and oil pollution aging. It can work stably for a long time in extreme environments of -60℃~+300℃, high oil pollution and high dust, being a special anti-loosening fastener for harsh industrial working conditions.
Controllable thread deformation ensures lasting and stable locking performance. It can maintain standard anti-loosening torque after multiple disassembly and assembly without locking, slipping or failure. Compared with disposable anti-loosening gaskets and glue locking methods, it greatly reduces equipment maintenance and replacement costs, ideal for equipment overhaul and repeated assembly scenarios.
Full Grade & Process Coverage for All Scenarios
Covers Grade 8 general carbon steel, Grade 10 high-strength carbon steel, 304 conventional anti-corrosion and 316 high-end anti-corrosion full series. Equipped with electro-galvanized, black oxide, Dacromet and stainless steel finishing processes, it adapts to indoor general, outdoor heavy-duty, high-temperature oil pollution and acid-base corrosion working conditions, meeting diverse procurement demands of various industries in one stop.
Grade 8 Carbon Steel DIN980V Lock Nut (General Bulk Type)
Made of high-quality carbon steel with standard hardness and excellent toughness, featuring stable locking torque. Electro-galvanized and black oxide finishes provide ultra-high cost performance. Suitable for anti-loosening fastening of ordinary mechanical equipment, light-duty steel structures and general sheet metal equipment under normal temperature and dry conditions, serving as the mainstream bulk product for foreign trade retail and industrial supporting.
Grade 10 High-strength DIN980V Lock Nut (Heavy-duty Industrial Type)
Reinforced by alloy steel quenching and tempering treatment, it has greatly improved tensile resistance, fatigue resistance and vibration resistance, with higher preset anti-loosening torque and stronger locking effect. Matched with Dacromet long-term anti-corrosion coating, it resists high and low temperature, aging and vibration, specially designed for heavy-duty working conditions such as construction machinery, wind power equipment, mining machinery and automobile chassis.
304 Stainless Steel DIN980V Nut A2-70 (General Anti-corrosion Type)
Authentic 304 stainless steel with non-magnetic, anti-oxidation and anti-rust properties. It resists humid air, rain erosion and mild acid-base environment, widely applied in ordinary outdoor projects, water treatment equipment, garden machinery and damp workshop equipment assembly, maintaining long-term stable performance in conventional corrosive environments.
316 Stainless Steel DIN980V Nut A4-80 (High-end Anti-corrosion Type)
Molybdenum-containing 316 stainless steel has superior salt spray, acid and alkali corrosion resistance compared with 304 steel. It adapts to extreme harsh working conditions such as coastal salt spray, chemical corrosion, high temperature and humidity, and high oil pollution. Featuring high mechanical strength and fatigue resistance, it is widely used in marine equipment, chemical machinery and high-end precision anti-corrosion equipment supporting.
Production Process
Graded Material Selection: Select raw materials by carbon steel, alloy steel and stainless steel grades, strictly control material composition and mechanical properties, and ensure unified batch quality from the source.
Precision Cold Heading Integral Forming: Automatic multi-station cold heading process ensures regular hexagon, flat end surface and standard aperture. The V-shaped deformation area is accurately positioned with no splicing gaps for integral forming.
High-precision Tapping Processing: Precision go/no-go gauge tapping with full thread profile and standard tolerance ensures smooth meshing and perfect matching with all standard bolts and screw rods.
Special Deformation Area Pressing: Professional molds accurately press the upper thread deformation area, strictly control the preset locking torque, and ensure uniform and stable anti-loosening effect without failure or over-locking.
Graded Heat Treatment Strengthening: Exclusive tempering process for Grade 8/10 carbon steel accurately controls hardness and toughness, improves fatigue and vibration resistance, and avoids loosening and deformation during long-term use.
Custom Anti-corrosion Treatment: Complete black oxide, electro-galvanizing, Dacromet, stainless steel polishing and passivation processes to meet anti-rust, high temperature resistance and corrosion resistance requirements of different working conditions.
Full-batch Precision Inspection: Test dimension accuracy, thread pass rate, locking torque, hardness and salt spray performance batch by batch, conduct strict graded sorting and provide complete factory qualification reports.
Application Industries
Construction Machinery Industry: Anti-loosening fastening of heavy equipment structures such as excavators, loaders and cranes (Grade 10 Dacromet type preferred).
New Energy Wind Power Equipment: Long-term anti-loosening assembly of wind power brackets, tower accessories and outdoor vibration equipment.
Auto Parts Field: Anti-loosening fixing of automobile chassis, suspension systems and engine peripheral high-temperature and oil pollution working conditions.
General Mechanical Equipment: Anti-loosening locking of automation equipment, transmission equipment and high-frequency vibration motor equipment.
Special Anti-corrosion Equipment: Anti-loosening supporting of water treatment, coastal marine and chemical corrosion equipment (304/316 stainless steel type preferred).
