Craftdady 100pcs 18K Gold Lobster Claw Clasps Stainless Steel Fastener Hook Closure End Clasps 9x5mm for Jewelry Craft Key Chain Making Review (2026)

What size these clasps actually are

At roughly 9mm long and 5mm wide, this is one of the smaller lobster claw clasp sizes sold for jewelry making, closer in scale to the clasps used on delicate bracelets and fine chain necklaces than the larger 12mm to 16mm clasps used on thicker statement pieces. Independent bead supplier listings for the same 9x5mm stainless steel lobster clasp size list a thickness of about 2.5mm and a 1mm attachment hole, dimensions consistent with a small, low profile closure rather than a bulky one. That scale makes the clasp easy to hide against the body of a finished piece rather than standing out as a visible hardware element.

Why stainless steel under gold matters

According to the listing, the clasps use a 304 stainless steel base with a gold colored plated finish, rather than a plated brass or zinc alloy base that some budget clasps use. Stainless steel resists rust and corrosion on its own, so even if the gold surface finish wears thin at points of repeated friction, such as where the lever is pinched open repeatedly, the underlying metal will not rust the way a plated base metal clasp can. This construction is common in mid tier findings that want to offer a gold look without the cost of solid gold or gold filled hardware.

Handling small clasps

Lobster claw clasps work with a small spring loaded lever that the wearer pinches to open the claw and hook it onto a jump ring or chain link. At this compact 9x5mm size, that lever is proportionally small, which some buyers with larger fingers, reduced dexterity or arthritis may find more difficult to operate compared with a larger 10mm or 12mm clasp. Buyers shopping specifically for ease of use, rather than a delicate finished look, may want to size up to a larger clasp even if it is slightly less proportional to a fine chain, especially for jewelry that gets put on and taken off daily.

Uses beyond standard jewelry

Because lobster clasps are a simple, reliable hook and catch mechanism, this listing also markets the clasps for key chain making and general craft closures, not only necklaces and bracelets. At this smaller size, however, the clasp is not rated for heavy loads, so while it will work for lightweight key fobs or small charm attachments, it is not a substitute for a heavy duty swivel clasp on a keyring meant to carry a full set of house and car keys. Matching clasp size to the expected load keeps the closure from bending or failing under stress it was not designed for.

Buying in bulk for a project

This listing sells 100 clasps per pack, which suits stringing or production work where many identical pieces are being assembled, such as a maker producing a batch of bracelets for a craft fair or online shop. Buying in bulk at this scale is typically more cost effective per clasp than purchasing small packs of 10 or 20, though it also means committing to one size and finish for the whole batch. Beaders who are still finalizing a design or who only need a handful of clasps for personal projects may prefer a smaller pack size to avoid excess stock sitting unused in a supply drawer for years.
