Bi-metal screw, namely bimetallic screw, is a kind of screw made of two different metals, usually combining stainless steel (such as SS300) and heat-treated carbon steel.
| Diameter | The diameter of bimetallic hexagon composite self-drilling screws usually ranges from 2.9 mm to 6.3 mm, and common specifications include M2, M2.5, M3, M4, M5, M5.5, M6, M6.3, etc |
| Length | Its length varies according to specific requirements, ranging from several millimeters to hundreds of millimeters. Common length specifications include 10 mm, 12 mm, 16 mm, 20 mm, 25 mm, 32 mm, 50 mm, 75 mm, 90 mm, 110 mm, and 125 mm, etc |
| Hardness | Different parts of the bimetallic screw have different hardness requirements. For example, the drill tip part made of carbon steel or alloy steel has a relatively high hardness after heat treatment, generally reaching about HRC50 - 60, so that it can smoothly drill into the connected materials |
| Tensile Strength | Common tensile strength grades include 4.8, 6.8, 8.8, 10.9, 12.9, etc |
