- Schnorr® Type S Serrated Safety Washers are in the form of a disc spring but with a trapezoidal cross-section and serrations on both sides. The outer diameter is matched to the head diameter of the pan head and socket head cap screws. For screws of property classes 8.8 and 10.9, higher pretension forces might be necessary. These are covered by our reinforced washers type “VS”. Due to the conical form, optimal traction is achieved at highest positive locking due to the helical gearing
- Schnorr® Washers offer the following advantages:
- Equivalent locking effect to wedge-locking washers
- Wide variety for materials and different finishes
- High resistance to vibration due to positive locking of the serrations
- Concentrical force transmission and uniform axial load eliminate bending torques and deformation of the bolt stem
- Maintains initial bolt tensio
- The design of the serrations prevents friction and damage to components when tightening
- Extremely high safety against loss of pretension force and loosening
- Wide variety for materials and different finishes
- The closed ring form results in high degree of pretensioning, while avoiding burst-open effect
- Development and design of the washers take place on the basis of the screw geometrics, tightening torque as well as the constructive circumstances
- Understanding and measuring washer sizing: Washer sizes can be a little confusing. M6 suits a M6 bolt. The inside diameter of a M6 washer is greater than 6mm to allow the washer to fit over the bolt
- Are Metric & Imperial Washers Interchangeable?: In most cases they are which is why we have added metric sizing to the imperial range and imperial sizing to the metric range. If you are still unsure or if the washer dimensions are critical click on the washer you are interested in and view the technical specifications table before ordering
- Dimensions: Our stock is genuine Snchnorr® product, sourced from Hobson Engineering, the Australian Distributor. Although the supply is consistent differences may exist between batches such as inside dimensions, outside thickness, visible stamping, appearance, packaging and actual finish
- Material / Coating: Stainless Steel A2-70 G304 is the most popular grade of stainless steel. It is aesthetically pleasing to the eye and very practical because of its excellent corrosion protection in most environments. Due to the shape and design serrated washers are not stamped. Stainless steels are largely non-magnetic but it is common for some stainless steel fasteners, especially stamped components like washers to show a small degree of magnetism which is a result of work-hardening during the manufacturing process
- Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
