M3*10 Aluminum Alloy Knurled Thumb Screws Hand Grip Knob Bolts Thread L:10mm

These screws use an M3 thread with a standard 0.5 mm pitch and a 10 mm threaded length. M3 × 0.5 is the most common M3 pitch and is compatible with the vast majority of M3 threaded inserts, hex nuts, and tapped holes used in electronics enclosures, optical equipment, and maker hardware.

Aluminum alloy thumb screws are well-suited for light-duty panel retention, cover plates, and adjustment mechanisms where hand-tightened torque is sufficient. They are not recommended for high-vibration structural joints or applications requiring torque values that exceed what can be applied by hand. For high-load structural use, consider steel equivalents.

Anodizing creates an oxide layer that is harder than bare aluminum and provides good resistance to mild corrosion and surface abrasion under normal indoor conditions. The finish is not rated for prolonged outdoor exposure to salt spray or harsh chemicals. For outdoor or marine environments, contact us to confirm suitability.

Yes. The M3 × 0.5 thread is fully compatible with standard M3 hex nuts, nylon-insert lock nuts, brass heat-set inserts, and tapped M3 holes. Ensure your mating thread depth is at least 10 mm to achieve full thread engagement.

Color selection is typically driven by two factors: aesthetics and function. For custom PC builds or maker enclosures, match the color to your build's theme. For technical assemblies, consider color-coding by function — for example, using Black for grounding points and Golden for signal-path adjustments — to speed up maintenance and reduce errors during reassembly.

Order 1 or 5 pieces for single-project repairs or prototyping. Choose 10 pieces for a small build with multiple adjustment points. The 50- and 100-piece tiers offer a lower per-unit cost and are practical for production runs, workshop stocking, or projects where you need consistent color across many fastener points.

Yes. M3 knurled thumb screws are commonly used on 3D printers for bed-leveling adjustment points, tensioner locks, and panel clips. On CNC machines and laser engravers, they work well for quick-release jig clamps and cover panels that require frequent access. Confirm that your application does not subject the screws to sustained vibration without a locking mechanism such as a nylon-insert nut or thread-locking compound.
