Knurled Screw Model The knurled screw model is a design of screw thread that has been textured to provide a secure grip on the user's hand when turning it. This design makes it easier for users to get a good grasp on the screw, even with gloves or in wet conditions. The knurls are typically raised and irregularly shaped, allowing them to dig into the user's skin and prevent slippage.
