Specification overview for HI2539017

The HIROBO HI2539017 is an M3 x 6 hexagon button bolt intended for use in RC helicopter general parts and similar small model assemblies. Its button-head hex design provides a low-profile fastening solution for areas where a neat finish is preferred.

Installation notes: fit with the correct hex driver and take care not to over-tighten to avoid damaging threads in aluminium or plastic mounts. Typical uses include fastening frame plates, servo brackets, and light-duty mounts that do not carry primary loads.

Service suggestions: keep spare bolts to hand and re-torque fasteners after flying; replace any bolt showing stripped threads or head distortion. For consistent installation, use steady hand torque and apply thread-locker only on joints that must stay fixed.

Which hex key size do I need for this M3 button-head bolt?

Use the hex key that matches the bolt head recess to ensure a tight fit. A correct tool engagement prevents rounding of the head and allows safe torque application.

Can I fit these bolts into nylon or ABS mounts?

They can be used in plastic mounts with caution. Avoid over-tightening and check that the thread length engaged is appropriate for the material thickness.

When is thread-locker appropriate for these fasteners?

Apply thread-locker where vibration is likely to loosen fasteners and where a permanent hold is desirable. For parts that require removal, use a removable-grade product or avoid thread-locker.
