Description

Tamper resistant button head machine screws with a pin-in hex socket drive provide secure fastening for industrial equipment assemblies. The combination of alloy steel base and black oxide finish delivers high strength and durable service in control panels, electrical enclosures, and heavy machinery.

Specs

  • Diameter: 5/16 inch
  • Thread pitch: 18 per inch
  • Length: 2 inch
  • Finish: Black oxide
  • Drive type: Pin-InHex Socket Drive
  • Material grade: Alloy Steel

Features

  • Tamper resistance: Pin-In Hex Socket Drive necessitates a compatible tool with precise alignment, reducing risk of unauthorized disassembly in security-critical machinery housings and access panels.
  • Bearing surface: Button head distributes clamping load over a broader bearing area, minimizing localized material stress on thin panels and enclosure skirts.
  • Strength and reliability: Alloy Steel construction delivers high tensile strength and structural integrity for high clamping forces in heavy equipment assemblies.
  • Finish and protection: Black oxide provides low reflectivity and surface protection; lubrication enhances service life in damp or dusty industrial environments.
  • Installation and compatibility: Pin-In drive improves torque transfer in automated lines and reduces tool slippage during insertion, supporting deterministic assembly processes.
  • Application domains: Suitable for control panels, electrical enclosures, machine frames, and industrial equipment requiring secure fasteners with tamper resistance.
