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
