This security machine screw is designed for commercial buyers who need a fastener that helps deter removal with ordinary screwdrivers. Its button-style Torx drive is suited to general-purpose fastening where controlled installation and a lower-profile head are preferred.

The screw has a 1/4-20 thread size and measures 2-1/2 inches long. It features an alloy steel construction, black oxide finish, and a button Torx head that requires a matching driver bit. Effective minimum order: 1 EA. Packaging information is separate from the minimum order and does not establish the quantity included with a purchase.


Key Features:

  • Security Torx Drive: Helps prevent removal using ordinary screwdrivers.
  • Matching Bit Required: Supports positive tool engagement during installation.
  • Button Head Profile: Provides a lower crown and shallower recess than a round-head screw.
  • 1/4-20 Thread, 2-1/2 in. Length: Helps buyers match the screw to compatible threaded applications.
  • Black Oxide Finish: Provides the specified finished appearance for the fastener.

Choose this machine screw when a 1/4-20, 2-1/2-inch security fastener with a button Torx head is needed for general-purpose fastening.
