Gibraltar 845590-G Spoked Knob 2 in 4 Point Cast Iron

Product Description

The GIBRALTAR 845590-G is a 4-point spoked knob designed for manual control applications in industrial, mechanical, and machine tool environments. Constructed from cast iron with a zinc finish, this knob provides a firm, durable grip for operators adjusting equipment by hand. The head measures 2 inches in diameter, making it easy to grip and turn under normal working conditions. The 3/8-16 threaded stem allows straightforward mounting to compatible shafts and threaded fasteners. Machinists, maintenance technicians, and equipment assemblers typically install this type of knob during machine setup or component replacement.

This spoked knob is suited for use on machine controls, jigs, fixtures, and industrial equipment where a sturdy hand-adjustable control point is required. The cast iron construction holds up in shop environments subject to oil, grit, and repeated handling. The 4-spoke design distributes grip load evenly and provides multiple contact points for turning leverage. It is appropriate for both original equipment assembly and field replacement on industrial machinery.
