Thumb Screws are hand-tightened fasteners designed for quick and tool-free assembly or disassembly. Featuring a large, textured or knurled head, thumb screws allow for easy grip and turning by hand, making them ideal for applications where frequent adjustments or removals are required.

These screws are commonly used in:

• Electronic enclosures

• Mechanical panels

• Fixtures and displays

• Furniture and equipment assemblies

Thumb screws are available in both slotted and non-slotted heads, and can come with flat, round, or winged designs, depending on user preference and functional needs.

• Brass or plastic – for decorative or non-conductive uses

Available in metric and imperial sizes, Adfast Component’s thumb screws are manufactured to precise standards, ensuring easy installation, secure fastening, and long-term durability.
