The GB860 standard deals with saddle shaped elastic washers, a type of washer with a saddle-shaped cross-section, which is usually used to provide preload and prevent bolts or screws from loosening. These washers are typically made of spring steel and can be surface treated, such as galvanized or blackened, to improve corrosion resistance and aesthetics.

Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.

Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.

Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.

Advantage:

Corrugated design: The corrugated design of the corrugated elastic washers enables them to provide elastic deformation during installation, which generates a preload force and effectively prevents loosening of the connecting parts. High elasticity: These washers have good elasticity, which can absorb vibration and shock to a certain extent and protect the connecting parts from damage. Corrosion resistance: Surface treatments such as zinc plating can improve the corrosion resistance of the washers, making them suitable for a variety of environmental conditions.

Scope of Application

Machinery and equipment manufacturing: In machinery and equipment manufacturing, for fixing and adjusting machine parts such as bearings, gears and motors. Building and civil engineering: in building and civil engineering, for joining beams, columns and other structural components to provide stable and reliable connections. Automotive industry: In automotive manufacturing, for connecting automotive components such as chassis and body fixings.
