This Gloxco brand standard wing nut assembly (wingnut assembly) is a replacement parts which is commonly found on vacuum tanks, manways, vacuum trailers, vacuum trucks, frac tanks, storage tanks, and pressure vessels.
Gloxco Premium Wingnuts are made of Ductile Iron which is much more fatigue and impact resistant than the cast iron found in traditional wing nut assemblies.
The most common break point for wing nut assemblies is where the handles meet the base. Our newly designed wingnuts are much thicker at this point to reduce breaking.
We redesigned the shoulder of our wingnut base to fit inside the manway lid. This will help center the lid and make installation easier.
Our wingnut assemblies include a wing nut, clevis pin, cotter pin, eye bolt, and washer.
Our most common complaint about other wingnuts is lost cotter pins. To fix this, we pre-crimp our cotter pin to hold it in place until you are ready to install.
These manway wing nut assemblies are non code. This means that they cannot be used on tanks that store or haul corrosives, explosives or combustible materials.
This wing nut assembly does not include a grease cap. If you are looking for a greasable wingnut assembly, try our part #WNA-58-GS-GR
