Small part, big impact on clamp security
Mounting screw for RRS PC-LR & PC-PRO clamps
The RRS 1/4-20 x 1.25 Mounting Screw is a custom-machined stainless steel fastener designed specifically for Really Right Stuff PC-LR and PC-PRO panning clamps, delivering a precise, play-free fit and long-term durability.
Compared to traditional coin-slotted screws, its hex-socket head accepts a 3/16" hex key (not included) and supports higher tightening torque, giving you a more secure connection for heavier camera and lens setups.
This dedicated screw is an ideal spare or backup option for photographers who want to maintain factory-spec performance on their PC-LR and PC-PRO clamps.
Hex-socket head for higher torque
The 1/4-20 x 1.25 Mounting Screw adopts a hex-socket interface that works with a standard 3/16" hex key, making it easier to apply consistent, high clamping force than with coin-slotted hardware.
This design gives you positive engagement and minimizes slipping under load, which is especially valuable when balancing longer lenses or heavier accessories on your PC-LR or PC-PRO clamp.
