Index Screws

Index screws are the slotted, knurled-head thumb screws used to make finger-tight, tool-free adjustments to mechanical assemblies, jigs, fixtures, and equipment panels. At the DIY Hardware Store, our index screws are available for the light engineering, woodworking jig, and general machinery applications where a positive, repeatable, non-permanent fixing needs to be made and released by hand.

The knurled or winged head provides sufficient grip for tightening by hand to a light clamping force, making index screws the correct fastener for fence settings on power tools, clamp positioning on workbenches, panel attachments on equipment housings, and any application where the fastener needs to be adjusted or removed frequently without tools. They engage with tapped holes or standard nuts and are available in the metric thread sizes most commonly encountered in machine tool and woodworking jig applications.
