When you're assembling electronics enclosures, access panels, or workshop fixtures and need a fastener you can tighten and release without reaching for a screwdriver, standard bolts become a constant frustration. These M6x30mm knurled thumb screws are designed for makers, hobbyists, and small-workshop builders who need reliable, repeatable hand-tightening in tight spaces or frequent-access applications.
Each thumb screw is machined from aluminum alloy with a knurled round head for a secure finger grip. The M6 metric thread runs the full 30mm (approximately 1.18 inches) of the shank. Available in 10 anodized color options — Red, Pink, Gold, Dark Blue, Light Blue, Black, Silver, Green, Purple, and Orange — so you can color-code assemblies or match your build aesthetic. Sold in quantities of 1, 5, 10, 20, or 50 pieces per order.
Typical use cases include securing computer case side panels for tool-free access, fastening 3D printer enclosure doors, mounting rack-mount equipment covers, and assembling DIY electronics project boxes where frequent opening is required. The knurled grip also makes these ideal as hand-tighten knob bolts for jigs and fixtures on woodworking benches.

These screws use a standard M6 metric thread. The pitch for M6 coarse thread is typically 1.0mm. If your application requires a fine-pitch M6 thread, please contact us to confirm before ordering.
Select the pack size that matches your build. A single PC case side panel typically uses 4 thumb screws, so a 5-pack covers one panel with a spare. For rack-mount builds or production runs, the 20- or 50-piece packs offer better value per unit.
These aluminum alloy thumb screws are designed for panel fastening, enclosure assembly, and light-duty fixture work where hand-tightening is sufficient. They are not rated for high-torque structural or load-bearing applications. For heavy mechanical loads, a steel fastener with tool-driven installation is recommended.
Anodizing is an electrochemical surface treatment that integrates into the aluminum rather than sitting on top like paint, so it resists chipping and peeling under normal use. Color may gradually wear on the knurled contact surfaces with very frequent handling over time, which is typical for anodized aluminum hardware.
Yes. These thumb screws use standard ISO metric M6 threads and are compatible with any M6 nut, M6 threaded insert, or M6-tapped hole. Ensure your application's thread depth can accommodate the full 30mm shank length, or that a nut is used to limit engagement depth if needed.
Each variant is a single color per pack. To order multiple colors, add each color variant to your cart separately. For example, add a 5-pack of Black and a 5-pack of Red as two separate line items.
The exact head diameter is listed in the variant options. If you need a specific head diameter for clearance or aesthetic reasons, please refer to the variant details or contact us to confirm before purchasing.
