Shop our complete selection of lobster clasps for jewelry making — the most popular and secure clasp type used by jewelry designers worldwide. Whether you call them lobster claw clasps, lobster clasp closures, or even lobster clamps, these spring-loaded clasps are the go-to choice for necklaces, bracelets, anklets, and keychains.
We carry lobster clasps in every size, finish, and material you need:
- Sizes from XS to XL — 9mm, 10mm, 12mm, 15mm, 19mm, 23mm, and 30mm+ options
- 10+ finishes — Gold, silver, antique brass, antique copper, antique silver, copper, gunmetal, satin Hamilton gold, bronze, and 14 karat gold
- Multiple materials — Solid brass with electro-plating, 316L stainless steel, and PVD waterproof gold
- Specialty styles — Standard trigger clasps, swivel lobster clasps, elongated teardrop clasps, and curb chain trigger clasps
Every lobster claw clasp in our collection is nickel-free, lead-safe, and hypoallergenic. Our brass clasps use a solid brass base that's slightly malleable — meaning the trigger mechanism won't snap or break like cheaper zinc alloy alternatives. Our stainless steel lobster clasps are built for permanent jewelry and everyday wear pieces that need to resist tarnishing and water exposure.
Which Lobster Clasp Size Do I Need?
Choosing the right lobster clasp size depends on your project. Here's a quick guide:
- XS (9–10mm) — Best for delicate necklaces, thin chains, and minimalist designs. Popular for permanent jewelry.
- Small (12mm) — The most versatile size. Works for most necklaces and standard bracelets. Our best seller.
- Medium (15mm) — Ideal for heavier chains, statement necklaces, and chunky bracelets.
- Large (19–23mm) — Used for heavy-duty pieces, multi-strand designs, and keychains.
- XL / Swivel (30mm+) — Swivel lobster clasps for keychains, lanyards, and bag charms that need rotation.
Lobster Clasp vs. Other Jewelry Clasps
Lobster clasps are the most widely used jewelry closure for good reason. Compared to other clasp types, they offer the best combination of security, ease of use, and versatility. Unlike spring ring clasps, lobster claw clasps have a larger lever that's easier to operate — especially for customers with limited hand mobility. Unlike toggle clasps, they stay locked under tension and won't accidentally open. And unlike magnetic clasps, they provide a positive mechanical lock that won't release near magnets or under pull force.
