RANDOLID PROTECTION CAPS

Radolid Protection Caps will ensure proper bolting, even after years of exposure to the elements!

Radolid Protection Caps are easily installed by pressing the cap onto the bolted joint by hand. The barbed edge snaps on and prevents the caps from accidental removal. Radolid Caps are reusable and can be reapplied to 2-3 times.

Standard Radolid Protection Caps are manufactured of low density black UV-resistant polyethylene that withstands temperatures of -84 °F to +210 °F. They are also resistant to water, brine, hydraulic fluid, diesel, greases, gasoline, hydrochloric acid concentrate, sulphuric acid to 40%, nitric acid to 40%, ammonia, and acetum.


There are TWO types manufactured:

  • Type 1 - for standard nuts or bolts without washers, 
  • Type 2 - for a nut or bolt with washer, and an adjustable telescopic two piece cap that can be produced in various lengths (It is even able to fit check nuts). 
Our caps are sized to fit heavy hex nuts only; they will not fit finished nuts properly. Radolid Protection Caps are manufactured in sizes to fit 1/4 inch to 3 3/4 inch diameter bolts or studs. High temperature material of Polyamid A4H for use up to +430 °F is available.
