M4-0.7 x 20 mm Flat Head Spanner Drive Security Machine Screws, 100-Pack

These M4-0.7 x 20 mm security machine screws are designed for buyers who need fasteners with a spanner drive that cannot be removed using ordinary screwdrivers. Their flat heads support a neat, flush installation in metal surfaces or countersunk placement in softer materials.

Each screw has an M4-0.7 thread, a 20 mm length, a flat spanner-drive head, and 18-8 stainless steel construction. The spanner drive requires a matching driver bit and is designed for positive tool engagement, torque transfer, and reduced slippage during installation. Pack includes 100 screws.

Key Features:

• Spanner security drive: Helps deter removal with ordinary screwdrivers.
• Matching-bit operation: Provides positive driver engagement for installation with less pressure and slippage.
• Flat head profile: Installs flush in metal surfaces and can be countersunk in softer materials for a clean finish.
• M4-0.7 x 20 mm size: Supports applications requiring this specified machine-screw thread and length.
• 100-count pack: Supplies multiple screws for installation and replacement needs.

Choose these flat head spanner-drive screws when your application calls for M4-0.7 x 20 mm stainless steel machine screws with a security-focused drive and a flush-fitting head.
