Buying Guide: How To Choose The Right Connector Bolts And Nuts
- Material matters: stainless steel (304) resists rust; carbon steel offers strength but may need coating for corrosion resistance.
- Bolt length: match to panel thickness. Longer bolts are for thicker materials; shorter for thin boards.
- Coating and finish: nickel or black coatings reduce oxidation; bronze cap nuts provide a decorative finish.
- Head type and drive: hex socket heads provide a clean look and easy adjustment with a hex key.
- Nut compatibility: ensure barrel nuts match the bolt thread diameter and length for secure tightening.
- Application suitability: avoid large machinery use with small hardware; designed primarily for furniture assembly.
