Really Right Stuff - Hex socket screw 1/4"-20x1.25" for mounting PC-PRO & PC-LR

Really Right Stuff hex socket screw 1/4"-20x1.25" for PC-PRO & PC-LR

Sometimes a single screw really does decide whether your setup is rock solid or gives way at the first twist. This 1/4"-20x1.25" hex socket screw from Really Right Stuff is made exactly for that moment: for reliably mounting your RRS panorama clamps such as PC-PRO and PC-LR on compatible RRS ball heads – no wobble, no fiddling.

Precision socket head cap screw made of stainless steel

What you get here is a socket head cap screw made of high-quality stainless steel, designed for long-term stability. No soft metal that rounds off after three uses, but a robust solution for photographers who regularly use their gear outdoors, even in rain, fog, or by the sea. The socket head ensures a clean contact surface and controlled force transmission when tightening, so your panorama clamp sits firmly and securely on the ball head.

1/4"-20 UNC thread for photo and video mounting

The thread follows the 1/4" UNC standard that you practically encounter everywhere in photography. This means the screw integrates seamlessly into your existing system and fits precisely with the corresponding RRS ball heads and panorama clamps. The 1/4"-20 thread ensures a secure fit without you feeling like you’re about to overtighten something, ideal if you frequently switch between different setups.

Well-thought-out dimensions for RRS panorama clamps

The overall length of the screw is 37 mm, with a thread length of 31 mm. That may sound like dry numbers at first, but in practice it’s crucial: the screw engages deeply enough in the ball head without being too long or hitting anything. It’s exactly this fine-tuning that makes mounting the RRS panorama clamps PC-PRO and PC-LR so pleasantly predictable: you simply screw it in, tighten it, and know that the length is right.

Installation with 3/16" hex key

For installation you use a 3/16" hex key. This is a common size that you’ll find in many tool kits, especially in the photo sector and with high-quality tripod systems. We like this solution because it lets you apply force in a controlled way without slipping, and because the hex socket head is much more discreet and secure in everyday use than some improvised screw head variant.

Optimized for PC-PRO & PC-LR panorama clamps

This screw is not just some standard part from the odds-and-ends box, but specifically designed for mounting the RRS panorama clamps PC-PRO and PC-LR on RRS ball heads. So if you want to refine your panorama setup or are looking for a replacement screw for your existing system, this part fits perfectly into the concept. No guesswork, no “it’ll probably work somehow”, but a precisely fitting solution for your RRS system.

Made in the USA, consistent RRS quality

The screw comes from the same quality philosophy as the well-known Really Right Stuff ball heads and clamps that are manufactured in the USA. You notice this in the smooth thread guidance, the precise head shape, and the overall very high-quality feel. It may be “just” a screw, but it integrates seamlessly into the premium RRS ecosystem and supports the precision for which this brand is known in professional photography.

For demanding panorama and tripod setups

Especially when you work with panorama heads and precise tripod solutions, you don’t want to compromise on the connection between ball head and clamp. This 1/4"-20x1.25" hex socket screw ensures that your PC-PRO or PC-LR panorama clamp sits securely, even when you use heavy cameras or longer lenses. That way you can focus on composing your image instead of wondering whether something might be coming loose somewhere.
