- Aluminum screw with tapered cylinder head (the other screw head dimensions, head height and head Ø correspond to ISO 4762/DIN 912-standard - just the head is tapered to save weight)
- rolled thread
- resistant anodized against ultra-violet light - the color shade won't fade away even unter sunlight exposure-
- glossy surface in various colors
- Material: high-strength aluminum 7075-T6 (aerospace quality)
- precisely CNC-machined, not forged for a smoother surface (that's why these bolts are slightly more expensive)
- Tensile strength: 540-600 N/mm²
- approx. 70% weight savinig compared to steel bolts
- Allen drive size depends on thread size/wrench size: M4/3mm, M5/4mm, M6/5mm, M7/6mm, M8/6mm
- strong chamfer at the thread start for easier turning into the counter hole
- Aluminum screws can be used in many ways. However, be aware of the lower strength compared to steel or titanium screws, so their use may be limited.
