Executive Standard:

ANSI UNJC aerospace thread specification

• Titanium alloys: Ti-6Al-4V, Ti-5-5-5-3, pure titanium
• Nickel-based superalloys: Inconel 718, Hastelloy, Monel, Waspaloy
• High-strength heat-resistant aerospace superalloy components
• Hardened ductile superalloys prone to work hardening

• Blind hole internal UNJC thread tapping for aerospace aircraft structural parts
• Energy equipment, turbine engine superalloy fitting threading
• CNC machining center automated mass production of Ti/Ni alloy threaded components
• New energy high-temperature resistant fastener manufacturing
• Precision controlled-root UNJC thread assembly requiring tight 3BX tolerance fit

• HSS-E PM powder metallurgy substrate: Far higher heat resistance and impact toughness than conventional HSS-E, resists chipping under superalloy high cutting temperatures
• TiCN low-friction coating: Greatly reduces built-up edge (BUE) adhesion of sticky titanium/nickel chips, minimizes friction wear and thread surface scratching
• Custom spiral flute geometry for superalloys: Optimized chip gullet to curl long ductile chips into small fragments, eliminates chip jamming inside blind holes
• 3BX UNJC aerospace tolerance: Strict controlled thread root profile meets aviation assembly safety standards, consistent precision in mass production
• Special chip-breaking chamfer design: Balances penetration ability and chip control for semi-bottom blind hole deep tapping
• Germany precision multi-stage grinding process, stable dimensional repeatability for long batch production runs
