DFRobot - M3x10 Low Profile Hex Head Cap Screw Set with Nuts (10 Sets)

M3 Hex Head Cap Screws (10 mm) provide a reliable fastening solution for electronics assemblies, robotics frames, and sensor mounting tasks. Designed for makers and engineers working with development boards, circuit modules, and mechanical brackets, this hardware set delivers secure fastening with a compact metric profile. The hex drive structure allows stable torque transfer during installation, reducing the risk of stripping compared with small Phillips fasteners. Suitable for prototyping benches, laboratory builds, and embedded systems projects, this metric screw and nut set helps create clean, durable mechanical connections across a wide range of electronics and mechanical integration scenarios.

Reliable Hex Drive for Secure Assembly

A hex socket head structure provides strong tool engagement and stable torque control during installation. Compared with small cross-head screws, the hex drive reduces slippage and stripping when tightening fasteners in tight electronics assemblies. This design improves reliability when securing circuit boards, sensor brackets, mechanical frames, and lightweight structural components commonly used in prototyping and robotics builds.

Standard M3 Metric Hardware for Electronics Projects

The M3 metric thread size matches the most common mounting standard used across development boards, sensor modules, and mechanical brackets in embedded systems. This compatibility allows seamless integration with spacers, standoffs, and threaded mounting holes found on many electronics platforms and accessories. The 10 mm screw length offers balanced reach for stacking boards, attaching brackets, or fastening lightweight structural parts.

Convenient Screw and Nut Combination

Each hardware set includes matching M3 nuts, enabling flexible installation even when threaded mounting holes are unavailable. This pairing supports a wide range of assembly approaches such as through‑hole fastening, bracket mounting, or custom mechanical fixtures. The included nuts ensure stable clamping force while simplifying prototyping workflows that require frequent adjustments or reconfiguration.

This compact fastening kit supports electronics prototyping, robotics assembly, sensor mounting, and educational engineering builds. The metric hardware set is well suited for laboratory setups, classroom engineering kits, and DIY mechanical structures where reliable small fasteners are required for mounting circuit boards, brackets, and lightweight structural components.
