Northwestern Knurled Head Screws: Precision Fastening Solutions

NW knurled head screws—often called knurled thumb screws or hand screws—are designed for tool-free tightening and quick adjustments in fixtures, guards, covers, and industrial assemblies (application dependent). The knurled head provides grip for hand tightening, making these screws a practical choice when parts need to be removed frequently or adjusted during setup. They’re commonly used in jig and fixture builds, machine guarding, access panels, and any application where you want repeatable clamping without reaching for a wrench or driver.

Available in standard knurled head configuration for direct hand tightening and hand knob screw assemblies that reduce operator fatigue in repetitive operations.
