Limiting reagents are the chemicals that limit the formation of the products in the reaction. Bolts will limit product formation.

Limiting reagents are the chemical reactants that are present in less quantity and get consumed first hence limiting the product formation. In the above case, bolts are limiting reagents as they are less in number and limit the formation of the nut bolt attachment.

Excess reagents are chemicals that are present in more quantities and remain even after the product is formed. Hence, nuts are excess reagents as they are present in more quantities and will remain even if bolts are finished.

Therefore, bolts limit product formation.
