M6 x10mm Grip Knob Bolt Knurled Thumb Screw Flat Thumb Screws Hand Tighten Screw

These are M6 metric screws with a standard 1.0mm coarse pitch. They are compatible with any M6-threaded insert, standoff, or tapped hole using the same pitch. If you are unsure whether your application uses M6, measure the hole diameter — M6 threads fit a 6mm nominal diameter hole.

The shaft length is 10mm (~0.39 in). This is the usable thread engagement length. For thin panels with a standoff or insert behind them, ensure the combined panel thickness plus insert depth does not exceed 10mm. If your panel is thicker, contact us to confirm fitment before ordering.

Aluminum thumb screws are designed for light-to-medium duty clamping — securing access panels, covers, and enclosure lids that are removed regularly. They are not rated for structural load-bearing joints or high-vibration environments where steel fasteners would be required. For PC case panels, 3D printer enclosures, and similar applications, they provide reliable retention.

Anodizing is an electrochemical surface treatment that penetrates the aluminum rather than sitting on top like paint, so it resists chipping and peeling under normal hand-tightening use. The knurled grip area may show wear marks over extended use, which is cosmetic and does not affect function. Avoid using tools to tighten, as over-torquing can damage the anodized surface.

Yes, provided your extrusion uses M6 T-nuts or threaded inserts. Standard 2020, 3030, and 4040 aluminum extrusion profiles commonly accept M6 hardware. You will need a compatible M6 T-nut seated in the slot — the thumb screw threads into the T-nut for tool-free panel attachment. Confirm your extrusion's slot width accommodates the T-nut before ordering.

For a single PC case or enclosure, 2–5 pieces per panel side is typically sufficient. If you are building multiple units or want spares, the 10 or 20-piece packs offer better per-unit value. For color selection, Black and Silver are the most neutral and blend with most builds. Golden, Royal Blue, and Wine Red are popular for accent builds. If you are color-coding zones (e.g., power vs. data panels), choose two contrasting colors and order accordingly.

Most modern PC cases use either M3 or #6-32 UNC thumb screws for side panels — not M6. These M6 screws are better suited for custom enclosures, aluminum extrusion frames, and DIY builds where M6 threads have been intentionally specified. Check your case manual or measure the existing screw diameter before purchasing to confirm M6 compatibility.
