  • Item Features
  • Papco® plated grade 5 cap screws are identified by the three radial bar head marking and are made of medium carbon steel, quenched and tempered for higher Tensile strength and holding power
  • Bright electroplated with chromate finish to resist rust
  • Medium carbon steel quenched and tempered C: 0.28 to 0.55, P: 0.025 maximum, S: 0.025 maximum
  • For studs only, sulfur content may be 0.13% maximum
  • There shall be a sufficient hardenability to ensure a microstructure consisting of approximately 90% martensite in the core of threaded sections of the fasteners after hardening and quenching and before tempering
  • Double heat treated
