#6-32 UNC Anodised Flat Head Knurled Thumb Screws — Aluminum, 10 Colors, Hand Grip Bolts

These screws have a shank length of 5.5mm (≈7/32"). This length is designed to provide secure thread engagement in standard #6-32 threaded standoffs and tapped holes commonly found in PC cases and electronics enclosures. If you need a different length, please contact us before ordering to confirm availability.

These aluminum anodised thumb screws are designed for hand-tightened, tool-free applications where moderate panel retention force is needed — not for high-torque or structural load-bearing joints. For standard PC case panels, access covers, and electronics enclosures, aluminum thumb screws generally provide sufficient clamping force. If you need higher strength, consider a stainless steel thumb screw variant.

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 widely used 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, durable oxide layer on the surface of aluminum. This layer improves scratch resistance, enhances corrosion resistance, and allows for 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.

Available colors include Wine Red, Pink, Golden, Blue, Sky Blue, Black, Silver, Green, Purple, and Orange. 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 5.5mm shank length. Color-coding is a practical way to organize panels or add a custom look to your PC build.

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. We offer packs of 1, 2, 5, and 10 pieces. The 10-pack is a practical choice for a complete PC build, while the 1- or 2-pack suits single replacements or testing a color before committing to a larger order.
