What Are Toilet Tank Bolts?
Toilet tank bolts are the fasteners that connect the toilet tank to the toilet bowl. They are typically made of stainless steel or brass and consist of two parts: a bolt and a nut. The bolt is inserted through the holes in the bottom of the tank and the bowl, and the nut is tightened to secure the tank in place.
Are Toilet Tank Bolts Standard?

The American National Standards Institute (ANSI) has established specifications for toilet tank bolts, ensuring that they meet certain dimensions and performance requirements. This standardization allows for interchangeability between different brands and models of toilets.
Standard Toilet Tank Bolt Dimensions
According to ANSI standards, toilet tank bolts have the following dimensions:
- Diameter: 5/16 inch (8 mm)
- Length: 2 inches (50.8 mm)
- Thread pitch: 18 threads per inch
Compatibility of Toilet Tank Bolts
Due to standardization, toilet tank bolts are generally compatible with most toilets sold in the United States. However, it’s always a good idea to check the manufacturer’s specifications to ensure compatibility before purchasing. Some older or non-standard toilets may require different bolts.
