20 Silver Plated Screw on Clasps – 15mmX3mm

Description

Screw On Clasps Silver Plated

The threaded mechanism inside these barrel closures delivers something lobster claws can’t: genuine mechanical grip that won’t pop open under tension. Each half screws into the other with three full rotations, creating a closure that holds firm on thick leather cord, braided nylon, or stacked wire strands where traditional spring-loaded findings struggle. The silver plated brass construction resists tarnish better than raw base metal while keeping the price accessible for production runs.

• Dimensions: 15mm length × 3mm diameter when closed
• Internal threading fits 1.5–2mm cord or wire with glue reinforcement
• Two-piece design with matching screw threads on male and female halves
• Pack of 20 individual clasps (10 complete pairs)
• Electroplated finish over brass base metal
• End caps accommodate cord ends, crimp tubes, or wire-wrapped loops

These 15mm jewellery clasps suit macramé necklaces where you’re finishing with wrapped cord ends rather than crimp beads—apply E6000 inside the barrel, insert your knotted cord, and let it cure for security that won’t unravel. They’re also the solution for kumihimo braids where the finished diameter sits around 2mm, giving you a closure method that matches the weight of the piece. Use them on leather cord bracelets layered three or four strands thick, where the screw action provides enough mechanical advantage to close even when the cord is stiff.

Thread quality varies wildly across imported findings—these barrel screw clasps have clean, consistent threading that engages smoothly without cross-threading or jamming. The interior chamber depth is 4mm on each side, giving you room to insert folded bead tips or wrapped wire if you’re converting a strung piece. Pair them with silver metal beads to maintain tonal consistency, or contrast against oxidized copper wire for a mixed-metal aesthetic. At this diameter, they sit proportionally on 7–8 inch bracelets without overwhelming narrow wrists.
