Buying Guide: Key Considerations For Stainless Steel Bullet Hinges
Material and finish: Choose 304 stainless steel for corrosion resistance in outdoor or humid environments. Brushed finishes help mask minor scratches.
Size and load: Match hinge length and pin diameter to your door, gate, or lid. Check load ratings per pair to ensure safe operation under expected weight.
Rotation: Most weld-on bullet hinges offer 360-degree rotation. Verify if your project needs full rotation or limited movement.
Mounting method: Weld-on hinges require welding to frame or door. Consider the thickness of materials and welding capabilities before purchase.
Maintenance: Some models include grease fittings (zers) for easier lubrication. This extends life in gritty outdoor settings.
