Papco® grade 5 cap screws, identified by the three radial bar head marking, are made of medium carbon steel, quenched and tempered for higher tensile strength and holding power
Double heat treated
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
