Schnorr 17 x 2mm HS Load Washer DIN 267 Geomet 321B 50pk

Schnorr is a German manufacturer of precision disc springs, safety washers, and load washers engineered for bolt-securing and load-sensing applications in industrial machinery, equipment assembly, and structural fastening. Schnorr safety washers use a patented radial serration system that locks under vibration to prevent bolt loosening without adhesives or thread inserts, making them a preferred solution in high-vibration environments.

Schnorr load washers and disc springs are precision-engineered conical washers that function as spring elements in bolted joints, absorbing differential thermal expansion, settling, and embedding losses to maintain consistent bolt preload over the life of the assembly. They are used wherever controlled, measurable spring force is required under a fastener or in a disc spring stack.

Where this product is used

Load washers and disc springs are used in precision engineering and structural applications:

• Bolted flanges and pressure vessel assemblies where gasket relaxation and thermal cycling require controlled bolt preload maintenance.
• Precision machinery where controlled spring force under adjustment screws and fasteners must remain consistent over time.
• Structural connections and bridge engineering where bolt preload monitoring and retention are specified in the design.

Selecting the right option

Disc springs can be stacked in parallel (same orientation) to multiply the load capacity, or in series (alternating) to increase deflection range. Load capacity and deflection are determined by disc geometry — refer to Schnorr disc spring tables for stack design and preload calculation. Match the bore and outside diameter to the fastener and counterbore dimensions.
