RS PRO Stainless Steel Clamping Lever, M12 Thread, 50 mm Insert Length, Die Cast Zinc Handle, 478-850

The RS PRO 478-850 Stainless Steel Clamping Lever is a high-quality solution designed for quick and secure fastening in settings where adjustments are frequent and tool-free operation is essential. This clamping lever features an M12 male thread and a 50 mm stainless steel insert, making it suitable for robust industrial, laboratory, maintenance, and machinery applications.

The lever handle, crafted from die cast zinc, delivers both strength and durability while remaining lightweight. Its ergonomic design ensures a comfortable grip, allowing operators to make repeated adjustments without discomfort. The black finish on the handle not only enhances grip but also presents a professional industrial appearance.

Inside the lever, an integrated ratchet mechanism provides easy operation. When the handle is pulled upward, the internal serrated system disengages, allowing the lever to be rotated freely to the desired position. Pressing the lever down re-engages the ratchet, enabling manual tightening or loosening of the connected screw without the need for additional tools or wrenches. This functionality accelerates routine adjustments and reduces downtime during equipment changes or maintenance.

The insert and shaft materials are selected for demanding environments: the insert is stainless steel, giving excellent corrosion resistance, and the shaft is robust steel for secure holding. The lever assembly is engineered for reliability in machine frames, tripods, metal stands, and various industrial fixtures where secure and repeatable clamping is required.

Whether used in height adjustment, fixture placement, or machinery maintenance, the RS PRO Stainless Steel Clamping Lever provides consistent performance and long-term dependability. Its suitability for hard-to-reach or confined spaces makes it popular in machine shops, production lines, test laboratories, metalworking, and equipment installation scenarios.

Clamping levers of this design are a practical solution wherever frequent repositioning, height adjustment, or quick-release fastening is part of the workflow. RS PRO's engineering ensures that even in environments exposed to grease, humidity, and temperature cycling, this lever offers reliable, ergonomic operation over many thousands of cycles.
