Kirk anti-twist set screw for Kirk quick-release clamps QRC-2.5, QRC-3, QRC-4

Kirk anti-twist grub screw for QRC-2.5, QRC-3 and QRC-4

Sometimes a tiny detail decides whether your setup is rock solid or slowly, almost imperceptibly, starts to twist. This is exactly where the Kirk anti-twist grub screw for the Kirk quick-release clamps QRC-2.5, QRC-3 and QRC-4 comes into play. Small and inconspicuous, but in practice extremely helpful when you want to secure your camera equipment reliably.

Precisely matched to Kirk quick-release clamps QRC-2.5, QRC-3, QRC-4

The Kirk quick-release clamps QRC-2.5, QRC-3 and QRC-4 feature, in addition to the classic tripod thread, an extra, smaller thread that is designed specifically for this special grub screw. This combination of main thread and auxiliary thread ensures that the clamp is not only screwed on, but also positively locked against twisting. So you are simply making consistent use of an existing, well thought-out design.

Anti-twist protection on the mounting plate

As soon as you insert the anti-twist grub screw, you reliably prevent the Kirk quick-release clamp from loosening or twisting on the mounting plate. Especially with heavier cameras, long telephoto lenses, or when you readjust frequently, a clamp can otherwise gradually shift. With this screw, the clamp remains stable in position, saving you nerves, time, and, in case of doubt, crooked image series in the long run.

Special design as a pin screw

This screw is a true custom-made part, designed as a precise pin that fits exactly into the auxiliary thread of the QRC-2.5, QRC-3 and QRC-4. It is not just some standard grub screw from the odds-and-ends box, but is matched to the Kirk system. For you, this means: precise fit, defined seating, no trial and error with unsuitable screw lengths or incorrect threads.

Scope of delivery: everything you need

The scope of delivery includes the actual grub screw, i.e. the anti-twist pin that you insert into the additional thread of your Kirk quick-release clamp. In addition, you get a matching hex key so you can mount the screw straight away without having to look for tools. You can basically use the set right after unpacking, without having to buy any additional parts.

Installation and handling in everyday use

Installation is straightforward: you screw your Kirk quick-release clamp QRC-2.5, QRC-3 or QRC-4 onto the mounting plate or tripod plate as usual and then use the additional thread for the grub screw. With the included hex key, you tighten it until the clamp sits free of play and twist-proof. Not excessively tight, but just enough so that nothing wobbles. In everyday use you generally do not need to readjust anything afterwards, unless you fundamentally change your setup.

Robust solution for demanding photographers

If you work with Kirk quick-release clamps, you probably value stable, reliable equipment. This anti-twist grub screw fits seamlessly into that concept. It increases the security of the connection between clamp and mounting plate without complicating the system. Especially for long exposures, macro shots, or series in which every minimal movement becomes visible, a twist-proof clamp is a real advantage.

Made in the USA, precision from the Kirk system

Like the matching Kirk quick-release clamps, the anti-twist grub screw comes from a manufacturing facility known for solid, practice-oriented solutions. The quality of the threads, the dimensional accuracy, and the interaction with the QRC-2.5, QRC-3 and QRC-4 clamps are all coordinated. The result is a small but important component that integrates seamlessly into your existing Kirk system and meaningfully complements its strengths.
