Knurled Head Captive Screws

Knurled thumb screws are a type of fastener designed for manual, hand-tightened applications where frequent adjustments or removals are necessary. They are characterized by a knurled, textured or ridged head that can be easily gripped and turned by hand, eliminating the need for tools. The knurling provides a non-slip surface, allowing users to apply sufficient torque for tightening or loosening without the use of additional tools. These screws often have a flat or raised head with the knurled surface, making them easy to grasp and turn with the thumb and fingers. Knurled thumb screws are commonly used in various applications, including equipment enclosures, electronic devices, and machinery, where quick and tool-free access is required. They are available in different materials, sizes, and thread types to suit specific application needs.
