Square Box Lock Clasp, 30 x 42mm

Square box lock clasp, 30 x 42mm, by Maya Metal. This stainless steel clasp is designed for trunks, cases, luggage, leather cases, and handmade storage projects that need a compact front closure.

The square profile works well for box lids, small trunks, display cases, craft boxes, and restoration projects. Choose the finish to match corner guards, hinges, handles, rivets, and other visible hardware.

Before ordering

• Confirm the 30 x 42mm visible clasp size fits the box front without crowding corner protectors, trim, stitching, or edge binding.
• Measure lid thickness, front wall thickness, leather covering, lining, and reinforcement before choosing screw length.
• Mark the center line of the lid and box body so the clasp tongue and receiver close straight.
• Compare screw-hole positions with existing repair holes if this clasp is for restoration or replacement.
• Use backing blocks or reinforcement on thin wood, soft leather panels, or frequently opened cases.
• Match silver, gold, or black finish with hinges, corner guards, handles, rivets, nails, and locks.
