Frequently Asked Questions
Q1Can aluminum sleeves really carry structural loads?
Yes. Our sleeves use 6061 or modified 7-series aluminum with heat treatment, delivering the strength needed for battery-pack mounting and lifting points while cutting weight by about 65% versus steel.
Q2How much weight can we save?
Aluminum density is about 1/3 of steel. Depending on geometry, finished sleeve and bolt assemblies typically save 60-70% of mass at equal envelope.
Q3Will aluminum parts cause galvanic corrosion on magnesium housings?
The risk is far lower than with steel fasteners because the potential difference is small. For harsh environments we supply coating packages for additional protection.
Q4What tolerances can you hold?
CNC machining with stable dimensional control for automated assembly; critical fits are inspected and reported with each batch.
Q5Do you support sampling before mass production?
Yes. Send drawings or 3D models and we provide engineered samples for validation before batch supply, with full inspection reports.
Q6Can the ZT68 bolt be customized?
Head styles (hex, hex-socket, Torx), shank diameter and length are customizable to drawing, with recommended torque data provided.
