Core technology is the nylon insert design: 1) Nylon ring hardness 72±5 Shore D, elastic recovery ≥85%; 2) Locking torque decay <15% after 10 removal cycles; 3) Initial locking force 1.3-1.5× standard bolts; 4) Zinc-nickel coating withstands salt spray ≥720 hours; 5) Nylon material resists oil and most chemicals; 6) Stable locking performance within operating temperature range; 7) Recommended installation torque 10% lower than standard bolts; 8) Nylon ring interference fit 0.2-0.4mm, providing consistent friction torque.
Covers M6 to M20, lengths 12-80mm. Detailed specs: 1) Nylon ring positioned 1.5×thread diameter from end; 2) Nylon ring width = 1.2×standard pitch; 3) 15° lead-in chamfer at thread start for easy installation; 4) Nylon ring inner diameter tolerance H8; 5) Overall weight 3-5% heavier than standard bolts; 6) Head marking includes locking symbol; 7) Locking torque test data per batch; 8) Thread accuracy 6g; 9) Nylon ring typically blue/orange; 10) Uncoated shank area ≤5mm.
Primarily for vibrating environments: 1) Automotive: Engine mount, transmission, suspension connections; 2) Rail transit: Bogie, car body connections; 3) Construction machinery: Hydraulic system, cab mounting; 4) Power generation: Diesel genset, pump unit connections; 5) Agricultural machinery: Tractor, harvester vibration points; 6) Compressors: Piping, bracket connections; 7) Conveying equipment: Vibratory feeder, conveyor frame; 8) Machine tools: Motor base, guard connections.
