Kirk LPS-1 1/4-inch screw, 12.5 mm long, for lens plates

Sometimes a tiny part decides whether your setup is rock solid or whether the camera twists at the worst possible moment. The Kirk LPS-1 1/4-inch screw with a length of 12.5 mm for lens plates is made precisely for that moment—small, inconspicuous, but surprisingly important in everyday use on the camera.

Captive 1/4"-20 screw for Kirk lens plates

The screw is designed as a captive 1/4"-20 screw and is specifically matched to Kirk lens plates. You screw it in once and normally don’t have to worry about it coming loose on its own or disappearing into your backpack. Especially if you work on location a lot, such a detail is worth its weight in gold, because you can rely on your gear instead of searching in the grass for a tiny screw.

Precise dimensions for a perfect fit

So that you know exactly what you’re working with, here are the exact dimensions, which we deliberately list in full because they really do matter in practice:

• Overall length: 15.8 mm
• Thread length: 5.6 mm
• Head length: 3.3 mm
• Head diameter: 10.7 mm

This combination ensures that the screw engages cleanly in the lens plate without protruding too far or being too short. Especially with longer telephoto lenses or heavy setups, this precise fit is crucial so that nothing wobbles or slowly works loose.

Round-head screw with 1/4" UNC thread

The Kirk LPS-1 uses a round head and a 1/4" UNC thread—the classic standard in photography that you know from tripods, quick-release plates, and many camera bases. The round head provides a comfortable bearing surface and runs smoothly in the plate without sharp edges or annoying corners. This keeps handling relaxed even when you frequently need to reconfigure or change the plate.

Hex key already included

You don’t have to rummage through your toolbox: a suitable hex key is already included. That may sound like a small thing, but in practice it’s very helpful when you can get started right away without first having to find the right tool. Especially on the go, in the studio, or when traveling, it saves you unnecessary fiddling and improvising with unsuitable keys.

Robust solution for your Kirk lens plate

The screw is specially developed for Kirk lens plates and matched to their geometry. It sits firmly, can be tightened in a controlled manner, and supports a stable connection between lens plate and lens or camera foot. If you work with long focal lengths, telephoto zooms, or generally heavier setups, this screw ensures that the plate stays exactly where it belongs—without play and without the annoying need to retighten every few minutes.

Quality, made in the USA

The LPS-1 screw is manufactured in the USA, and you can tell in the best possible way: cleanly cut 1/4" UNC thread, precise head dimensions, and workmanship that doesn’t look like a disposable part. It may be just a screw, but it’s one you want to rely on in everyday use. And that’s exactly what it’s made for.
