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.

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.
