Invented in England in 1841 by Whitworth, the Whitworth screw is distinguished by its 55-degree thread angle and triangular threads. As the first standardized screw type, it's expressed in inches and marked with the symbol "W."
Whitworth screws are integral to the waterworks and construction industries, where precision and reliability in fastening are paramount. Their design ensures higher accuracy and durability, making them suitable for applications demanding tight tolerances.
These screws feature a unique 55-degree thread angle, differing from the 60° angle commonly found in metric and other inch screws. Their dimensions, including the outer diameter and thread pitch, are measured in inches, catering to specific engineering and manufacturing requirements.
Materials for Whitworth screws vary, with selection crucial for ensuring strength and safety in critical applications. Protection against electrical corrosion is important, particularly when combining different metals like aluminum and stainless steel. Surface treatments are chosen based on corrosion resistance, aesthetic quality, and cost considerations.
Proper use of Whitworth screws involves ensuring the tightening force and repetitive forces like vibration are within safe limits. It's essential to prevent damage to the fastened objects and the screws themselves. Preventative measures against loosening include using loosening adhesives, double nuts, and specifically designed products to maintain the integrity of fastened objects, particularly in applications where safety is critical.
