Spring Snaps

Spring snaps are small tension-based fasteners that open and close with a spring-loaded gate; they are commonly used for attaching keys, tools, lanyards, pet leashes, light rigging, and temporary securing of straps or small components

Choose a size based on the thickness of items you’ll clip and the snap’s gate opening; check each product’s rated working load or breaking strength and pick a snap with a safety margin above the weight and dynamic forces expected in your use

Stainless steel and zinc-plated or nickel-plated steels offer good corrosion resistance for general and outdoor use; brass and solid stainless steel perform better in marine or wet environments, while lighter aluminum options trade some strength for weight savings

Most spring snaps in this category are intended for light to medium loads and general utility, not for critical life-safety uses like climbing or industrial fall protection; always verify manufacturer ratings and use certified hardware for safety-critical applications

Keep snaps clean and free of grit, lubricate the hinge and spring with a light oil if they become stiff, inspect regularly for corrosion or deformation, and replace any snap showing cracks, reduced spring tension, or damaged gates

Spring snaps typically range from budget options under $10 for basic small snaps to higher-priced heavy-duty or stainless models that cost more per piece; pricier options generally offer stronger materials, higher load ratings, and better corrosion resistance

Compare the snap’s eye or swivel inner diameter to the diameter of your strap or rope and the thickness of any mounting hardware; for swivels, ensure the swivel joint is sized and rated for the intended motion and load
