Sometimes nothing helps: metric screws, bits, and sockets are neatly arranged in the workshop, but your camera equipment has imperial screw connections. This is exactly where the Grainger products in our shop show their strengths. Here you’ll find imperial tools, matching accessories, and special UNC photo threads that work seamlessly with American standards, without you having to improvise.
Especially in the photo and video sector, the topic of UNC threads comes up again and again. Many tripods, quick-release plates, or mounts rely on the classic 1/4 inch or 3/8 inch UNC photo thread. If you then only have metric screws at hand, things quickly get fiddly. In this category you’ll find screws and nuts with UNC photo threads that can be screwed in cleanly, hold without play, and don’t wear out after just a couple of uses.
We place great value on cleanly cut threads, properly finished surfaces, and dimensions that truly match common photo thread standards. This allows you to securely fasten cameras, lighting equipment, microphone arms, or monitor mounts without having to mess around with adapters and makeshift solutions that end up wobbling anyway.
Many people know the situation: you’re standing in front of a device from the USA, want to loosen or replace a screw, and realize that no metric wrench really fits. With imperial screws and nuts from Grainger, you get exactly the fasteners that fit camera plates, lens plates, replacement lens feet, or telephoto rails. No fiddling, no half-baked solutions.
In our range you’ll find different lengths and head types so you don’t have to search for long when repairing, modifying, building your own gear, or looking for a spare. The right UNC screws and nuts are quickly found here.
As soon as you’re dealing with inch dimensions, metric tools will only get you so far. Yes, sometimes they sort of fit, but in the long run you’ll ruin screw heads and sockets. The imperial tools from Grainger are precisely designed for inch dimensions and grip screws and nuts exactly as intended.
