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

1/4" UNC photo thread screw round head 1", the small screw for big photo ideas

With this 1/4" UNC photo thread screw with round head and a thread length of 1", you equip your gear the way it should have been from the start: clean, stable, compatible with common photo accessories, and pleasantly unobtrusive in use. It fits classic 1/4" 20 UNC photo threads, like the ones you know from tripods, quick-release plates, camera plates, or various mounts.

Precise 1/4" 20 UNC photo thread for cameras, plates, and mounts

The screw has a clean 1/4" 20 UNC thread, the typical photo thread you know from cameras, tripod heads, and accessories. The thread is a right-hand thread and runs smoothly, so you can securely fasten accessories without having to worry every time that something might cross-thread or feel odd when tightening. In practice, the 1" thread length is more than sufficient for plates, adapters, clamps, or DIY solutions where you need a bit more “meat” in the material.

Round head with compact dimensions, unobtrusive but reliable

The round head is deliberately kept compact so it doesn’t get in the way, yet still offers enough contact surface to clamp components securely. The head height is about 0.132" (around 3.32 mm), the head diameter about 0.437" (approximately 11 mm). That may sound like dry numbers at first, but in everyday use it ensures that the screw grips firmly without appearing bulky or bumping into adjacent parts.

18-8 stainless steel, robust material for continuous use

The screw is made of 18-8 stainless steel. In practice this means: you can use it in the studio, outside in the rain, or in a dusty rehearsal room without having to worry about flash rust or unsightly discoloration after a short time. 18-8 stainless steel is a proven alloy that combines strength and corrosion resistance—ideal when your equipment should not only look nice but, above all, work reliably for a long time.

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

The round head is equipped with a hex socket for a 5/32" hex key. This allows you to tighten the screw much more precisely and firmly than with a slotted or Phillips head, without damaging the surface. One point is particularly important, and we explicitly emphasize it: for this screw you need a special imperial 5/32" hex key. A standard metric hex key usually does not fit properly, sits loosely, or in the worst case rounds out the head.

Please also note: the matching 5/32" hex key is not included. So if you have only metric tools in your kit so far, it’s worth planning for an imperial key right away so you can use the screw truly safely.

Areas of use in photography, from tripod plates to DIY rigs

The 1/4" UNC photo thread screw with round head is suitable for a wide range of applications: for mounting cameras on plates, upgrading quick-release plates, attaching accessories to mounts, rails, or DIY rigs. Wherever a classic 1/4" UNC photo thread is needed, it integrates seamlessly. Especially if you want to replace existing screws that are worn out, too short, or simply impractical, this 1" thread length version is a solid, durable option.
