Small Square Box Lock Clasp, 31 x 21mm

Small square box lock clasp, 31 x 21mm, by Maya Metal. This compact stainless steel clasp is designed for small trunks, jewelry cases, miniature trunks, leather cases, craft boxes, and repair projects.

The smaller 31 x 21mm size works well where a full-size trunk lock would look too large. Use it for compact lids, small storage boxes, display boxes, sample cases, and decorative leather goods.

Before ordering

• Confirm the 31 x 21mm clasp face fits the lid and front wall scale of the small box or case.
• Measure panel thickness, covering thickness, lining thickness, and available screw depth before installation.
• Align the lid and box body before marking screw holes so the clasp closes cleanly.
• For replacements, compare screw-hole spacing and visible footprint with the old clasp before ordering.
• Use reinforcement behind thin wood, soft leather, or sample-case panels that will be opened often.
• Choose silver, gold, or black to match hinges, handles, corner guards, rivets, and other visible hardware.
