Speciality Fasteners Schnorr Safety Washers - M5

The Speciality Fasteners Schnorr Safety Washers are designed to provide an innovative solution for secure fastening, featuring a serrated disc spring with trapezoidal cross-section.

These washers are engineered to match the internal diameter of screws and bolts, ensuring compatibility with a wide range of thread diameters. The outer diameter is matched to the head diameter of pan-head and hexagon socket head cap screws and bolts, allowing for versatile usage.

The unique design combines the benefits of frictional security and mechanical locking, providing an effective solution against loosening. Advantages include:

• Optimal resistance to vibration, thanks to the serrations' positive locking effect;
• High degree of pretensioning, resulting from the closed ring form;
• No bending in bolts, due to concentric application of force;
• Tightening without damaging surfaces, featuring sliding surfaces;
• No splitting during tightening, with a proper transitional radius between bolt shaft and bolt head;

The Schnorr Safety Washers are suitable for normal duty applications and can be used with captive fitting on a wide range of bolts. They come in packs of 10, making them a convenient solution for various fastening needs.

Key features:

• Suitable for use with practically any screw and bolt type, including those with recessed heads (excluding countersunk screws and bolts)
• High resistance to vibration
• Optimal locking effect at the outside diameter

The Speciality Fasteners Schnorr Safety Washers are designed to provide a reliable and efficient fastening solution for various applications, ensuring secure connections and preventing loosening.
