Product Description
The ASSY A2 Stainless Steel Kombi screw is an engineered structural wood screw that is corrosion resistant and self-tapping. The screw design also reduces wood splitting while offering a precise setting without the need for pre-drilling. Code-approved reliability, the ASSY A2 Kombi has been awarded an ICC-ESR approval in the United States.
| Diameters | 5/16″ (8 mm) , 3/8″ (10 mm) |
| Lengths | 3-1/8” (80 mm) to 7-7/8” (200 mm) |
The hex head is engineered for installation using either a socket or a bit for multipurpose applications. The reinforced and tapered shoulder below the screw head ensures a tight fit in pre-drilled steel plate holes. The tapered shape enables the screw to self-center. The ASSY A2 Kombi screw is equipped with a regular hex head, in order to achieve the best steel-to-wood connections. When used in wood-to-wood connections, the ASSY A2 Kombi screw can also be driven with a regular AW 40 Bit.
