M5 304 SS A2-70 METAL BOLT Carriage Bolt Passivated Round Head Square Neck
Product Description
Cold-forged M6 blank is thread-rolled after solution annealing, giving a smooth 6g flank that raises fatigue strength 30 %. Passivation removes free iron, leaving a satin chrome finish that resists print corrosion in humid workshops.
| Industry | Usage |
|---|---|
| Automotive | High-strength applications in engines, heavy-duty machinery, and bridge construction |
| Mechanical | Connecting mechanical parts, circuit boards, engines, transmissions in various industries |
| Energy | Connecting power generation equipment and transmission lines |
| Architectural | Building structures, shipbuilding, and petrochemical equipment |
The large half-round head sits flush in playground hand-rail inserts; the square neck bites into a 6.2 mm punched hole so one worker can tighten the nut from below the deck.
Key Features
No sharp edge meets EN 1176 safety code; A2-70 offers 700 MPa tensile with 50 µm chrome-oxide film for 800 h salt-spray, cutting life-cycle cost versus painted screws.
