1/4" UNC photo thread screw round head 5/8"

1/4" UNC photo thread screw, round head 5/8", small screw, big difference

With this 1/4" UNC photo thread screw with round head, you’re adding exactly the part to your setup that you’re always looking for when something on the tripod, quick-release plate, or camera accessory is wobbling. We keep noticing: a cleanly built rig often doesn’t fail because of the camera, but because of that one right screw – this is it.

Precise 1/4" 20 UNC photo thread for cameras and accessories

The screw has a precisely manufactured 1/4" 20 UNC photo thread – the classic standard thread you know from camera bases, tripod heads, quick-release plates, and lots of accessories. The thread is a right-hand thread and runs smoothly without scratching or catching, so you can easily screw it into metal, matching adapters, or plates. The thread length extends right up to the round head, allowing you to really use the full length without wasting any “dead” areas.

Round head with compact dimensions for low-profile, clean setups

The head is designed as a round head and remains pleasantly low with a head height of about 0.132" (around 3.32 mm). At the same time, the head diameter of approx. 0.437" (about 11 mm) provides enough contact surface so that the screw sits securely and the attached part doesn’t twist. Especially when you’re mounting flat plates, rails, or brackets, this compact round head is practical because it doesn’t protrude unnecessarily and doesn’t bump into the housing or other components.

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

The 1/4" UNC photo thread screw is made from 18-8 stainless steel. For you, this means high stability, very good corrosion resistance, and a screw that won’t give up quickly even after many uses in the studio, out in the rain, or in dusty environments. Especially with photo and video gear that’s constantly being mounted and dismounted, this material is a real advantage because the thread doesn’t wear out quickly and the screw also keeps looking good for a long time.

5/32" hex socket, precise installation with the right tool

The round head features a hex socket designed for a 5/32" hex key. This gives you significantly more control when tightening than a slotted or Phillips head, especially when you’re working with limited space or the screw sits in a recess. It’s important, and this is easy to overlook, that you need a dedicated imperial 5/32" hex key for this; metric sizes usually don’t fit properly here. The matching key is not included, so please keep that in mind if you don’t already have one in your toolbox.

For photo and video, rigs, plates, and custom solutions

Whether you’re upgrading a quick-release plate, attaching a small rail to your tripod head, adapting a slider, or simply replacing a lost screw on an accessory: this 1/4" UNC photo thread screw with round head is made exactly for such tasks. Thanks to the standardized photo thread, it can be combined with common camera components, and the compact head shape ensures that it also fits well in tight setups. Especially if you like building your own solutions or lightly modifying existing equipment, having such a screw in your kit is almost a must.

Notes on use and compatibility

The screw is designed for 1/4" UNC photo threads and is therefore suitable for common connections in the photo and video sector. When using it, make sure not to cross-thread it and only screw it into matching UNC mounts so you don’t damage either the screw or the mating part. With a suitable 5/32" hex key, you can tighten and loosen it in a controlled way without damaging the head or slipping.
