Product Details
Product Description
The 12.9 grade hexagon screw is mainly used for heavy-duty stamping applications and earth-moving machinery such as bulldozers and excavators. Their tensile strength is 170,000 psi (1200Mpa), which is 10% stronger than our other metric steel screws.
The dimensions comply with ISO 4017 (formerly DIN 933) specifications. The length is measured from under the head.
