Material: Carbon Steel
Hardness: 100HV, 200HV, 300HV
Surface treatment: natural color, blue and white zinc plating, color zinc plating, hot-dip galvanized modulation blackening, Dacromet
High strength blackened serrated locking washer, made of quenched high-strength spring steel as the base material, surrounded by precision sharp serrated design, can firmly clamp the contact surface, prevent loosening and displacement, and the surface blackening treatment improves wear and oxidation resistance. The structure is stable, the elasticity is good, and the cost-effectiveness is outstanding. It is suitable for high-strength fastening scenarios such as heavy machinery, industrial equipment, automobiles, and agricultural machinery.
