Hirobo HI2538009 Countersink Disk Screw M3 x 26 Phillips Head Helicopter Screw 10pcs  [HI2538009]

Countersink screw for RC helicopters

This Hirobo HI2538009 set contains ten countersink disk screws sized M3 x 26 intended as RC-scale helicopter hardware for general fastening tasks. The countersink head sits flush when installed, reducing protrusion on shell panels and small structural fittings.

Use these screws where an M3 x 26 countersink specification is required; they suit general helicopter assemblies and small component joints. During installation, seat the head fully and tighten only until firm to avoid stripping threads or deforming thin parts.
