These M4 x 0.7 x 40 mm security machine screws are designed for buyers who need a fastener that cannot be removed with ordinary screwdrivers. Their spanner-drive design helps secure installed components while the flat head supports a neat, flush finish where appropriate.

This 100-pack includes 18-8 stainless steel machine screws with M4 x 0.7 threading and a 40 mm length. Each screw has a flat spanner-drive head and requires a matching driver bit. Flat heads install flush in metal surfaces or can be countersunk in softer materials.


Key Features:

  • Spanner-drive design: Helps prevent removal with standard screwdrivers for added installation security.
  • Matching-bit operation: Provides positive tool engagement for installation with reduced slipping and pressure.
  • Flat head: Supports a clean, flush installation in metal surfaces.
  • 18-8 stainless steel: Provides the specified stainless steel construction for the application.
  • 100-piece pack: Supplies multiple screws for installation and replacement needs.

Choose these flat-head spanner-drive machine screws when M4 x 0.7 threading, a 40 mm length, and a matching-bit security drive are required for a flush-looking installation.
