turnlock

Turnlock, or turn lock, is a type of fastener commonly used in fashion hardware for bags, wallets, belts, and some garments. It consists of two interlocking parts: a fixed base component mounted on one side and a rotating latch or bar attached to the opposite side. The latch is turned to engage a catch or slot, securing the two parts together; turning it back releases the closure. Some designs use a post-and-slot arrangement with a rotating disk or bar that locks when turned a specified amount.

Materials and variants vary, but turnlocks are typically made from metal alloys such as brass or zinc and finished with brass, nickel, gunmetal, or antique coatings. Variants include flat turnlocks used on purses, barrel or cylindrical turnlocks for thicker straps, and decorative or high-security styles that incorporate detents or springs. The mechanism is generally designed to be compact and unobtrusive while providing a reasonably secure closure.

Applications include handbags, wallets, purses, luggage, belts, and some outerwear closures. Turnlocks are valued for their simple operation, low profile, and decorative potential. They can be visually prominent on certain designs and may require careful alignment when closing. Over time, repeated turning or rough handling can wear the rotating component or the base. Proper care includes keeping them clean and dry and avoiding excessive force if misalignment occurs.

History and usage: Turnlocks have long been part of leatherworking and fashion hardware, gaining widespread use in the 20th century and remaining common in contemporary accessories for both functional and decorative purposes.
