Description

Tamper-resistant machine screws engineered for professional industrial assemblies. Button head with pin-in 6-lobe drive provides secure fastening and tamper resistance across harsh environments.

Specs

  • Dimensions: Length: 1/4 inch
  • Finish: Stainless steel
  • Drive type: Pin-In 6-lobe
  • Material grade: 304 Stainless Steel

Features

  • Tamper resistance: Security drive requires compatible tooling, reducing risk of unauthorized adjustments within equipment housings and control panels.
  • Corrosion resistance: 304 stainless steel offers high resistance to corrosion and oxidation in industrial atmospheres and washdown areas.
  • Load distribution: Button head design distributes clamping force over a broader area to minimize material deformation and fastener pull-through in panel assemblies.
  • Secure installation: Pin-in drive alignment improves torque transfer and resists cam-out under vibration common in industrial equipment.
