Stainless Steel 304/316 Mushroom Head Bolt JIS with Elliptic Neck / Flashbolt

Product Specification

 Mushroom Head Bolt Elliptic Neck/Flashbolt Profile Stainless Steel 304/316 JIS Round Head Bolts

Highlights at a glance

1.Corrosion-Resistant Stainless Steel Construction: Flshbolt Profile Round Head Bolts are precision-forged from ASTM-certified SUS 304/316 stainless steel—delivering exceptional resistance to chloride-induced pitting and crevice corrosion in coastal, chemical, and infrastructure applications across North America.

2.JIS E 1107–2008 Compliance for Rail & Transit Systems: Engineered to meet JIS E 1107 mechanical tolerances and tensile requirements (≥500 MPa UTS), these Round Head Bolts are validated for critical fastening in railcar assembly, signaling hardware, and trackside Bolts & Studs systems.

3.North American Load-Bearing Reliability: Each Flshbolt Profile batch undergoes full traceable mill testing per ASTM A967 for passivation and ISO 898-1 hardness verification—ensuring consistent performance under dynamic shear and vibration loads typical in heavy-duty Bolts & Studs deployments.

4.Optimized for High-Frequency Installation: The Round Head Bolt geometry—featuring a 15° bearing surface and controlled head height per JIS E 1107—reduces installation torque scatter by up to 22% vs. generic profiles, accelerating MRO cycles in industrial and transit maintenance facilities.

5.Zero-Risk Material Traceability: Full heat-lot documentation, RoHS/REACH compliance, and PMI-certified alloy verification accompany every shipment—supporting ASME BPVC, CSA Z245, and AAR M-1002 certification workflows for Bolts & Studs in regulated North American sectors.
