Silicone Flanged Cap – #122 Range


Washer Caps or BAKEWELL FLANGED CAPS offer a simple solution where an uncoated area around a stud is required for an earthing point for instance.

  • Stud or pin and area around it
  • 315°C
  • Re-Usable


The Washer Cap or BAKEWELL FLANGED CAPS are stocked in most popular sizes from M3 to M12, with varying flange diameters to cater for differing customer needs.




Like all BAKEWELL products, the washer cap is manufactured from temperature resistant silicone rubber. This is colour coded on popular sizes for ease of identification. The washer cap can be used in many finishing operations such as electro-static powder coating, E-Coat, anodising & plating.

Other applications for this washer cap are numerous. Pivot points and anti vibration feet and spacers have also been resolved using the washer cap. A simple yet versatile design, like most of the AFAC range.

Application  of the washer cap is simply to push over the stud after any pre-cleaning operations, processing, and pull off after stoving, preferably while still hot. Any coating build up can be removed by rubbing between finger and thumb, or by rumbling.

If the standard sizes don’t quite do what you need, custom mouldings are also available through the AFAC tech team. One of our technicians will assist you through the design, prototype and production process to deliver you exactly the part you need. AFAC is all about solutions so if you have an issue that a silicone rubber part can fix, we want to hear from you.
