RS PRO Silver Aluminium Multiple Lobes Clamping Knob M10 Threaded Through Hole 50 mm 478-387

The RS PRO 478-387 is a silver aluminium clamping knob designed for reliable and repeatable holding force in mechanical assemblies and industrial hardware applications. This component features a robust aluminium construction, offering excellent resistance to corrosion, scratches, and wear under general and heavy-duty usage. Its polished silver surface ensures prolonged operational life and easy maintenance in demanding environments.

This clamping knob utilizes a multiple lobes design, often referred to as a star grip, which provides ergonomic handling. The five-groove shape means the user can achieve precise tightening and comfortable adjustments, even when torque needs to be modified frequently or under load. The 50 mm diameter offers a substantial grip, while the design allows for use with gloves in industrial workshops or factories.

The knob is constructed with a threaded through hole for M10 fasteners, making it compatible with standard M10 bolts and studs. The 22 mm thread length provides ample engagement for secure mounting, helping to prevent loosening during vibration or repeated use. The 30.9 mm overall hole length is engineered to accommodate longer thread engagements or additional adjustment range, further improving flexibility in your setups.

Engineered for general-purpose and specialist hardware, this clamping knob is well-suited for machine assembly, jigs, fixtures, woodworking equipment, and adjustment panels. Its aluminium body reduces weight compared to traditional steel alternatives while still maintaining high mechanical strength, offering an ideal balance for users requiring frequent manual adjustments in their applications.

The bright silver finish is not only aesthetically appealing, it also provides increased visibility and corrosion resistance. The clamping knob will maintain its integrity and appearance even after extended use. Typical industrial applications include machinery, enclosures, furniture assembly, conveyors, control panels, and maintenance hardware where quick-release and hand operation are important.

Key specifications include an M10 thread size, a 22 mm thread length, a 50 mm knob diameter, 30.9 mm hole length, and a multiple lobed/star knob shape. Assembly is straightforward and does not require special tools. The product is suitable for a broad range of environments, from manufacturing floors to laboratory or commercial settings, and offers lasting performance in both static and frequently adjusted roles.
