M5 M10 Stainless Steel Metal Thumb Screw SUS304 SUS316 Spade head Knurled thumb screw Custom size

Thumb screws are multi-purpose fasteners designed for manual tightening and loosening without tools. Their ergonomic design makes them ideal for applications where space constraints prevent the use of standard tools or where frequent access is required.

Knurled thumb screws feature a patterned surface around the head that significantly improves grip and torque application. This machining technique creates ridges or bumps that increase friction against fingers, making manual installation easier and more secure.

304 stainless steel offers excellent corrosion resistance and formability, making it ideal for general-purpose applications. 316 stainless steel provides enhanced corrosion resistance, particularly in chloride environments, due to its molybdenum content.

• Clean regularly with mild detergent and soft cloth
• Avoid acidic or alkaline cleaners that may damage the surface
• For stubborn stains, use specialized stainless steel cleaners
• Rinse thoroughly after cleaning and dry with a soft cloth
