#6-32 UNC Anodised Flat Knurled Thumb Screws 6mm — Aluminum, 10 Colors, PC Case Hand Grip

These screws have a shank length of 6mm (≈1/4"). This length provides slightly more thread engagement than the 5mm or 5.5mm variants and is generally suited for PC case panels, side covers, and expansion slot covers where the standoff depth is marginally deeper. Always measure your standoff depth before ordering to confirm the correct length. If you need a shorter or longer shank, see our other #6-32 thumb screw listings.

These aluminum alloy thumb screws are designed for hand-tightened, tool-free applications where moderate panel retention force is needed — not for high-torque structural joints. For standard PC case panels, access covers, and electronics enclosures, aluminum thumb screws generally provide sufficient clamping force for secure retention through repeated use. For higher-load applications, a stainless steel thumb screw is typically recommended.

These screws are made from anodised aluminum alloy, which provides good corrosion resistance for typical indoor use. The anodised coating adds an additional layer of surface protection compared to bare aluminum. However, they are not specifically rated for outdoor, marine, or high-humidity environments. For demanding outdoor applications, a stainless steel thumb screw is generally the more suitable choice.

These screws use the #6-32 UNC (Unified National Coarse) thread standard — the most common thread size in US-standard PC cases, server chassis, and electronics enclosures. They are compatible with any standard #6-32 threaded standoff, tapped hole, or nut used in ATX, Micro-ATX, Mini-ITX, and most rack-mount enclosures. Always verify the thread specification of your chassis standoffs before ordering.

Anodising is an electrochemical process that creates a hard oxide layer on the aluminum surface, improving scratch resistance, enhancing corrosion resistance, and producing vibrant, long-lasting color finishes. Anodised thumb screws generally hold their color better over time compared to painted or coated alternatives — making them a popular choice for custom PC builds and color-coded panel systems where appearance matters.

Most ATX PC cases use 2–4 thumb screws per side panel, plus additional screws for expansion slot covers and drive bay covers — typically 6–12 screws total for a full build. The 10-pack suits a single PC build, the 20-pack is ideal for two builds or a mixed-color setup, and the 50-pack is suited for workshop stock or bulk replacement needs. The 1- and 5-packs are convenient for single replacements or testing a color before committing to a larger order.

No. The anodised color finish is purely aesthetic and does not affect thread dimensions, shank length, or mechanical performance. All color variants share the same #6-32 UNC thread and 6mm shank length. Color-coding is a practical way to organize panels, differentiate fastener locations, or add a custom look to your PC build.
