The Unifix Form A Washers DIN 125A HV140 BZP are precision-engineered for professional tradespeople and DIY enthusiasts requiring reliable load distribution in heavy-duty structural applications. Designed to meet DIN 125A standards, these M24 washers feature a bright zinc-plated finish that provides enhanced corrosion resistance for long-term durability, though they are specifically sized for M24 fasteners and are not suitable for smaller bolt diameters.

DIN 125A refers to the German industrial standard for flat, circular washers, ensuring consistent sizing and physical characteristics across manufacturers.
The bright zinc plating provides good protection in standard conditions, but they are not recommended for long-term exposure to salt air or highly corrosive environments.
No, these are precision-engineered for M24 fasteners. Using them with smaller bolts will result in poor fit, while they will not fit on larger bolts at all.
HV140 refers to the Vickers Pyramid Number, indicating the surface hardness of the metal to ensure it can withstand clamping forces.
Generally, it is recommended to use new washers when performing critical repairs or structural installations to ensure the integrity of the tension.
Verify that your fastener is a true M24 size. If the bolt has damaged or deformed threads, the washer may not slide on easily.
If the protective zinc layer has been scratched or breached, clean the area and apply a corrosion-resistant coating or replace the washer.
For optimal performance, ensure that the mating surfaces of your workpiece are clean and free of debris before installation. Place the M24 washer onto the bolt shank before tightening the nut to ensure the load is distributed correctly against the surface. When tightening, use calibrated tools to reach the required torque specifications for your specific project. While the bright zinc plating offers significant corrosion resistance, it is advised to keep the washers dry and stored in a moisture-controlled environment to extend their lifespan, especially if they are being used in damp or humid working conditions.
