DESCRIPTION

Serrated S Safety Washer 304 Stainless Steel M27x39.0x2.5 (Box=10)

(Price per unit)

The oiginal SCHNORR® 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.

SCHNORR® safety washers are available in two versions:

The standard safety washer type "S" is available for screws of sizes M1.6 to M36 and of the property classes up to 8.8

For screws of property class 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.

Advantages

1) High resistance to vibration due to positive locking of the serrations

2) Concentrical force transmission and uniform axial load eliminate bending torques and deformation of the bolt stem

3) The design of the serrations prevents friction and damage to components when tightening

4) Extremely high safety against loss of pretension force and loosening

5) Wide variety for materials and different finishes

6) The closed ring form results in high degree of pretensioning, while avoiding burst-open effect

7) Development and design of the washers take place on the basis of the screw geometrics, tightening torque as well as the constructive circumstances.

Note: To ensure optimum strength, corrosion resistance, and long-term performance, washers should be selected from a material compatible with the bolt and nut. For example, use zinc washers with zinc fasteners, and galvanised washers with galvanised fasteners.
