Description
A 20 mm snap hook in die-cast zinc alloy, for straps that need to be clipped on and off rather than stitched in place. The gate is spring-loaded and opens one way, so a loaded strap stays put unless the latch is deliberately pulled.
What 20 mm Actually Refers To
On a snap hook the quoted size is the internal width across the eye — 20 mm here, which takes 20 mm webbing or a D-ring of matching wire diameter. It is not the overall length. Buyers who order a “20 mm hook” and receive a part their strap will not pass through are almost always working from the outside dimension, so confirm the eye width against your webbing before the order goes to tooling.
Where Snap Hooks Fail on a Bag
The spring, not the body. Zinc alloy bodies rarely break. Springs fatigue, and a hook with a soft spring hangs open under load. Every lot is gate cycle-tested before it ships, not just sampled at the start of the run.
The gate nose. All the load passes through a small contact patch where the gate meets the D-ring, and that is where plating wears through first. Rack plating keeps coating on the nose and the inner eye, not only on the flat faces that get photographed.
Burrs inside the eye. A casting burr left in the eye saws through webbing on every swing of the bag. Eyes are tumbled and inspected before plating, because this is invisible until the webbing has already been cut.
