-
Standard Compliance: Made in accordance with the DIN603 standard.
-
Material: Constructed from stainless steel, typically A2 (equivalent to AISI 304) or A4 (equivalent to AISI 316) grades. A2 stainless steel offers good corrosion resistance in general environments, while A4 stainless steel provides even better corrosion resistance, making it suitable for highly corrosive environments such as coastal or chemical settings.
-
Head Design: Features a smooth, round head (mushroom-shaped), which distributes pressure evenly, reduces surface damage, and provides an aesthetically pleasing appearance.
-
Neck Design: A square neck beneath the head prevents the bolt from rotating during tightening, ensuring a secure connection and eliminating the need for additional washers.
-
Thread: Metric thread, available in full or partial threading depending on the length. Common thread diameters include M5, M6, M8, M10, M12, M16, and M20.
