M5 x 12 medium head captive thumb screws straight knurl A2 Black Stainless Steel

What are captive thumb screws with straight knurl?

These are specialized fasteners designed for tool-free tightening and loosening.

• Medium Head: The head size is balanced, offering a grip that's easy to handle while not being overly large, making it suitable for tight spaces.
• Captive: This means the screw is retained in the application even when loosened, preventing loss or misplacement. It’s commonly used in applications where the screw needs to remain attached for convenience and compliance with safety regulations.
• Thumb Screw: Designed for manual operation without tools, allowing quick adjustments.
• Straight Knurl: The knurled pattern on the head enhances grip and ensures secure manual tightening, even with wet or oily hands.
• Material: A2 stainless steel provides excellent corrosion resistance, durability, and suitability for various environments, including outdoor or mildly corrosive settings.

These screws are widely used in industries such as electronics, machinery, and equipment assembly where frequent adjustments or maintenance are required.
