Northwestern Steel Hand Knobs: Durable Manual Control Solutions

Professional-Grade Steel Knobs from Your Trusted Michigan-Based Distributor

NW steel hand knobs—often called clamping knobs or machine knobs—are designed for tool-free tightening and repeatable adjustments in fixtures, guards, covers, and industrial equipment (application dependent). Steel knobs are commonly selected when you want a more robust, heavy-duty option for higher-use environments, especially where durability and long-term wear resistance matter. They’re widely used in jig and fixture builds, machine guarding, access panels, and adjustable stops where fast hand tightening improves setup speed.

Heat-Treated Steel with Black Oxide Finish - Smooth Comfort - Northwestern Tools steel hand knobs feature heat-treated steel construction with black oxide finish for maximum durability and corrosion protection. A smooth finish ensures hand comfort even after repeated use, making these knobs ideal for high-frequency adjustment operations. Available in multiple configurations: blank (for custom machining), reamed (precision-reamed holes with faces square to the hole), tapped (threaded holes with faces square to the hole), and thumb screw knobs (hexagon, single prong, and tee knob styles for specialized applications).
