1/4" UNC photo thread screw round head 2"

1/4" UNC round head photo thread screw 2", the small screw for your big everyday camera use

Sometimes a tiny part decides whether your setup looks solid or more like a wobbly makeshift solution. This 1/4" UNC round head photo thread screw with a length of 2" clearly belongs to the first category: inconspicuous, but extremely useful in use. You use it for camera plates, accessory mounts, rigs, rails, small adapters – everywhere the classic 1/4"‑20 UNC photo thread is the standard.

Precise 1/4"‑20 UNC photo thread for photo and video equipment

The thread is designed as a 1/4"‑20 UNC photo thread, exactly the size you know from tripod threads, quick-release plates, and typical camera adapters. The thread type is UNC with a right-hand thread, as is common in photography. This lets you screw the round head screw easily into camera plates, mounts, cages, or other components without fiddling or improvising.

The thread length extends right up to the head, so you really have the full 2" length available as usable thread. Especially when you have to go through several components, such as plate, spacer, and accessory, this extra reach pays off.

Round head with compact dimensions, unobtrusive but functional

The head is designed as a classic round head. With a head height of about 0.132" (around 3.32 mm), it remains pleasantly low without sticking out too much. At the same time, the head diameter of approx. 0.437" (about 11 mm) offers enough surface area so the screw seats securely and the component is firmly fixed. Not an oversized block, but a head that blends discreetly into your setup.

Especially with camera plates, clamps, or rails, this combination of low head height and sufficiently large diameter is practical, because nothing protrudes annoyingly while still clamping everything securely. It may seem almost trivial, but if you’ve ever snagged on bags, straps, or other parts with screws that were too tall, you know why these details matter.

18‑8 stainless steel, robust, corrosion-resistant, and suitable for everyday use

The screw is made from 18‑8 stainless steel. This means you can also use it in more humid environments, outdoors in the rain, or in changing temperatures without immediately worrying about rust or seized threads. Especially in photo and video work, where you might be at the beach, in the woods, or on wet city pavement, this is more than just a nice extra.

The stainless steel also provides pleasant stability. The screw is designed for long-term use, not for screwing in once and then throwing away. If you like to build your equipment cleanly and for longevity, this material fits very well into a high-quality setup.

5/32" hex socket, precise assembly with a special key

The screw is driven by a 5/32" hex socket. This is an imperial hex socket that gives you very controlled, play-free power transmission. You can tighten the screw properly without damaging the head, as often happens with improvised solutions using the wrong tools.

The following point is important, and we emphasize it quite deliberately: for this screw you need a special 5/32" imperial hex key. A metric hex key usually does not fit properly here, sits too loosely, or does not engage correctly. The appropriate key is not included in the scope of delivery, so you should make sure you have a suitable 5/32" hex key on hand before integrating the screw firmly into your system.

Areas of use in photography, from tripod plates to accessory mounts

This round head screw is designed for typical photo and video applications. You can use it wherever a 1/4" UNC photo thread is required: for mounting cameras on plates, securing mounts to rails, connecting accessories to rigs, or building custom mounts for monitors, microphones, or lights.

Because the thread length extends right up to the head, the screw is also well suited when you want to bolt several components together in sequence. For example, you can run it through a camera or lens plate, a spacer, and a mount without running out of thread. This makes it flexible, especially if you like to build your own solutions or adapt existing systems to your way of working.

Technical details at a glance, without frills

So you don’t have to search for long, here are the key data clearly summarized once again, without marketing fluff:

• Screw type: round head
• Thread type: 1/4"‑20 UNC photo thread
• Thread direction: right-hand thread
• Thread length: right up to the head, total length 2"
• Material: 18‑8 stainless steel, corrosion-resistant
