Overall winner: 1/2 in. x 3-1/2 in. Carriage Bolt Kit, ceramic black ruspert coating

Key Differences

Zonon (A) is a stainless steel kit that includes nuts and washers in a 5/16-18 size and is positioned at a more affordable price tier; Makers Bolt (B) offers a ceramic black Ruspert rust-resistant coating and larger 1/2" x 3-1/2" bolts for greater corrosion protection but is limited to that single diameter. Choose Zonon if you need stainless-steel hardware in 5/16-18 and a complete replacement kit; choose Makers Bolt if you need heavier 1/2" carriage bolts with enhanced rust resistance
