This 8-32 x 1/2 in. security machine screw is designed for buyers who need a fastener with a drive style that resists removal by ordinary screwdrivers. Its button head profile supports general-purpose fastening applications.

The screw has a button hex socket head and a 302HQ/18-8 stainless steel designation. Its security drive requires a matching driver bit for installation and removal. Effective minimum order: 1 each.


Key Features:

  • Security drive: Helps deter removal with ordinary screwdrivers.
  • Matching bit required: Supports proper engagement for installation and removal.
  • Button head profile: Provides a lower crown and shallower recess than a round head screw.
  • 8-32 x 1/2 in. size: Helps buyers match the fastener to compatible threaded applications.
  • Minimum order: Available with an effective minimum order of 1 each.

Choose this button-head security machine screw when a matching security driver bit is available and a tamper-resistant fastening option is needed.
