M10 Aluminum Knurled Thumb Screws – Anodized Hand Grip Shoulder Bolts, 70–100mm, 10 Colors

M10 is the nominal thread diameter: 10mm (approximately 3/8"). The standard coarse pitch for M10 is 1.5mm per ISO 68-1, meaning there are approximately 16.9 threads per inch.

To confirm compatibility:

• Measure your existing screw or tapped hole with digital calipers
• Use a thread pitch gauge to verify the 1.5mm pitch
• Check your assembly's BOM or engineering drawing for the M10 x 1.5 thread callout

All lengths are measured as the shank length, excluding the head. Choose based on your tapped hole depth or the combined thickness of the materials being clamped. General guidelines:

• Minimum recommended thread engagement for M10: approximately 10–15mm (1.0–1.5× diameter)
• For thin panels with a tapped hole: select a length that provides at least 10mm of thread engagement
• For through-bolt applications (clearance hole + nut): add panel thickness + nut height to determine minimum shank length
• A screw that bottoms out before clamping will not hold securely; one that is too short will strip the threads

Measure your application before ordering. When between sizes, choose the longer option.

These thumb screws are made from aluminum alloy with an anodized finish. Aluminum is significantly lighter than steel and resists corrosion well in most environments. At M10 size, aluminum thumb screws are suited for hand-tightened panel fastening and light-duty clamping — not for high-torque or structural load-bearing applications. For applications requiring higher clamping force, a steel thumb screw or standard hex bolt would generally be more appropriate.

Anodized aluminum generally offers good corrosion resistance in light outdoor and humid environments — significantly better than bare carbon steel. The anodized layer seals the aluminum surface against moisture. For most sheltered outdoor applications, these should perform well. For harsh marine, salt-spray, or highly corrosive environments, stainless steel would typically be a more appropriate choice.

Yes. These screws follow the standard M10 × 1.5mm pitch metric coarse thread specification per ISO 68-1 / DIN 13, and are compatible with any standard M10 tapped hole or M10 hex nut. This is the most common and widely available thread pitch for M10 fasteners worldwide.

Ten anodized colors are available: Royal Blue, Green, Golden, Dark Red, Black, Silver, Purple, Rose Red, Sky Blue, and Orange. The anodized color coating is applied to the aluminum surface and does not affect the thread dimensions or fit. All color variants share the same M10 × 1.5mm thread specification. Colors are useful for panel color-coding, custom builds, and visual identification of different access points.

Common applications include:

• Tool-free panel fastening on electrical enclosures and control boxes
• Access door latching on equipment housings in workshops and light industrial settings
• Jig and fixture assembly where quick reconfiguration is needed
• Rack-mount equipment panels and server enclosures
• Custom PC builds and modding projects
• Color-coded panel identification in complex multi-zone installations

Yes. Each size and color combination is available in packs of 1, 2, or 5 pieces. Ordering a single piece first is a practical way to verify thread fit, shank length, and color before committing to a larger quantity for a production build or installation project.
