Hirobo HI2538011 Countersink Disk Screw M3 x 30 - 10 pcs  [HI2538011]

Flush-Head M3 Screws for Helicopter Models

The Hirobo HI2538011 is a 10-piece set of countersunk Phillips disk screws sized M3 x 30, intended for model helicopter maintenance and assembly. The stainless finish and countersunk head let rotorheads and airframe plates sit flush against mating surfaces.

Use these fasteners where a recessed head prevents contact with rotating parts or linkages. The Phillips drive fits common model tool sets and the countersunk disk head spreads load to reduce point stress on composite or plastic parts.

Installation notes: start each screw by hand into a properly countersunk hole to avoid cross-threading, then tighten with a correctly sized Phillips driver until snug while avoiding excessive torque that can strip M3 threads in soft materials. For repairs and setup, replace matched screws together to preserve geometry and balance across paired components.
