Bag Lock Hardware

Bag Lock Hardware — Twist Locks and Magnetic Snaps
Closure hardware is the first thing a customer touches and the first thing that breaks. We manufacture twist locks, turn-locks, and sew-in magnetic snaps in zinc alloy, plated to your colour card, for flap bags, clutches, and structured handbags. Because a lock is worked by hand hundreds of times over the life of a bag, we treat mechanism quality as a specification, not an afterthought.
Types We Produce

Twist locks (turn-locks) — the classic closure for flap and structured bags. The tolerance between the turning bar and the catch decides whether the lock closes with a satisfying click or grinds. Ours are cast and machined to a matched tolerance, not assembled from loose parts.
Push locks — a cleaner alternative for minimalist designs, operated with a thumb press.
Magnetic snaps (sew-in) — for soft closures on totes and clutches. Magnet strength is graded; we will ask what the closure has to hold before recommending a grade, because an under-specified magnet is the most common complaint in this category.

Details That Decide Whether the Lock Survives

Magnet retention — cheap snaps use weak or unmagnetized discs; ours use NdFeB magnets that hold strength through the plating process.
Back-cap design — exposed screw backs scratch the bag lining. Our snaps use capped backs as standard.
Spring fatigue on twist locks — the return spring is cycle-tested so the lock still snaps back after thousands of openings.

Finish and Testing
Locks are rack-plated for even coverage on visible faces, nickel-free and lead-free, and pass 24 / 48 / 72-hour CASS salt-spray testing plus a 2,000-cycle alcohol abrasion test on the finish. Colour is matched to your approved sample and checked batch to batch under D65 light.
Sampling and Lead Times
Custom lock shapes and logo engraving start with a free 3D drawing. Tooling takes about 15 days — lock mechanisms are among the more complex moulds we cut — PP samples ship in 3 days, and bulk production runs 20–25 days. See our mould-making guide for how the tooling process works.
