Anodized Aluminum Hand Tightening Screw, Non-Standard Fastener

This hand tightening screw is integrally CNC machined from RoHS compliant aluminum alloy with anodized surface and knurled teeth design. It can be tightened and disassembled manually without tools, serving as a practical non-standard fastener.

Used for fixing side panels, expansion modules and internal parts of computer cases. It needs lightweight design and proper friction of knurled surface to prevent slipping during repeated operation. The anodized layer provides good insulation to protect electronic components, and uniform appearance matches the overall style of equipment.(Panoramic View PC Case   & Colorful Backlit Keyboard)

Applied to outdoor gears and portable camping devices. The product requires light weight and reliable structural strength to resist sunlight, moisture and minor impact. The anodized finish is scratch-resistant, fade-proof and anti-corrosive, ensuring easy operation even in humid or low-temperature outdoor environments.

For fastening housings, modules and access panels of household and commercial coffee machines. It must resist water stains and oxidation caused by moisture and coffee residues. The comfortable knurled design enables quick disassembly for daily cleaning and maintenance.
