Hex Flange Serration Screw with Dual-Lock Vibration Proofing

Product Description
 

Hex Flange Serration Screw with Dual-Lock Vibration Proofing

Engineered for 100% fastener retention in 15G+ vibration environments—where loosening = catastrophic system failure.

Dual-Lock Mechanism:

360° Radial Serrations bite into mating surfaces, resisting >12,000 cycles at 30Hz (per ISO 16130 Class B), eliminating rotational slip in engine mounts or rail bogies.

Pre-Applied Anaerobic Adhesive (Loctite 271 equivalent) maintains 95% torque retention after 1,000h salt spray (ASTM B117), critical for under-hood or outdoor exposure.

High-Clamp Flange Design: 40% larger bearing surface vs. standard hex screws, delivering 18 kN clamping force at M10 (ISO 898-1 Grade 10.9)—prevents gasket creep in power transformers.

Tool-Ready: External hex (ISO 4014 compliant) ensures zero cam-out with standard 12-point sockets, even in confined spaces (<5mm clearance).

Industry Applications
 

Ideal where loosening costs >$1,200/min in downtime (per 2025 Deloitte Industrial Survey):

Automotive Manufacturing: Engine blocks, transmission housings, and EV battery trays—survives -40°C to 150°C thermal cycling (SAE J2339 validated) without adhesive degradation.

Heavy Machinery: Excavator booms and hydraulic manifolds—resists shock loads up to 50G (ISO 10816-3 compliant), preventing fluid leaks.

Rail Transit: Bogie frames and pantograph mounts—meets EN 45545-2 HL3 fire safety and 500,000km no-loosening warranty (Alstom specification).
