D-Series Precision Bolts for Wirtgen W1000 Pavers, XCMG RP953E Pavers - Screed Adjustment Mechanism Bolts
D-series precision bolts are designed for screed adjustment mechanisms of pavers like Wirtgen W1000 and XCMG RP953E. Made of 45# steel with precision machining, they have a thread tolerance of 4h, ensuring an adjustment accuracy of 0.1mm to meet asphalt pavement smoothness requirements. The head and shank are integrally forged without welding defects, with a torsional strength of 800N·m. Hard chrome plating on the surface achieves a hardness of ≥HV700, reducing wear during adjustment and extending service life. Equipped with anti-loosening washers, they maintain stable adjustment positions during continuous paver operations, avoiding wavy patterns on the road. ISO 9001-certified and fully interchangeable with original parts, they are key fasteners ensuring paving precision.
