Knurled Screws

In stock

A knurled screw is a screw with a textured surface (knurling), usually on the head, designed for easy hand-turning without tools. The knurling provides enhanced grip, making it useful for frequent adjustments and in situations where tools are inconvenient. They come in various head styles (like thumb screws) and are used across many industries for tool-free fastening and adjustments.
