These tamper-resistant cap screws are designed for maintenance professionals and commercial buyers who need to secure assemblies against removal with ordinary screwdrivers. Their specialized drive design adds protection where a more controlled fastening solution is needed.

Each screw has a 5/16-18 thread size, a 1-1/2 in. length, a flat socket head, and 18-8 stainless steel construction. The 50-pack uses a security drive that supports positive engagement and high-torque transmission while helping resist cam-out and tool wear. A matching driver bit is required for installation and removal.


Key Features:

  • Tamper-resistant drive: Helps prevent removal with ordinary screwdrivers for added fastening security.
  • Flat socket head: Provides the specified head style for compatible fastening applications.
  • 18-8 stainless steel: Delivers the specified stainless steel construction.
  • Positive drive engagement: Supports high-torque transmission while helping resist cam-out and tool wear.
  • 50-piece pack: Supplies multiple matching fasteners for installation or replacement needs.

Choose these 5/16-18 x 1-1/2 in. security cap screws when a flat socket head, 18-8 stainless steel construction, and a matching security driver system fit your fastening requirements.
