This 1/4-20 x 3/4 in. security machine screw is designed for buyers who need a fastening solution that helps deter removal with ordinary screwdrivers. Its specialized Torx-style security drive is intended for applications where controlled access to installed hardware is important.

The screw has a 1/4-20 thread size and a 3/4 in. length. Its flat head is designed to install flush with metal surfaces and can be used in countersunk softer materials for a clean finished appearance. The security drive requires a matching driver bit for installation or removal. Minimum order quantity: 1 each.


Key Features:

  • Security drive: Helps prevent removal with ordinary screwdrivers for added fastening security.
  • Matching-bit operation: Uses a compatible driver bit for positive tool engagement during installation.
  • Flat head profile: Installs flush with metal surfaces for a clean appearance.
  • 1/4-20 x 3/4 in. size: Provides the stated thread size and screw length for compatible machine-screw applications.

Choose this flat-head security machine screw when a 1/4-20, 3/4 in. fastener with a specialized drive and flush-fitting head is needed. Confirm that the required matching driver bit and application thread requirements are compatible before ordering.
