AERATED CONCRETE SCREW KBRM 8x90 10pcs

The coarse-threaded lightweight concrete screw securely attaches wooden subframes, supports, brackets, rims, and braces to lightweight concrete (Siporex) and lightweight expanded clay aggregate (Leca) without pre-drilling. Thanks to the Nano coating, the KBRM is also suitable for outdoor use. Easy and quick to use, the Sormat lightweight concrete screw features a countersunk head and Torx drive. The carbon steel screw is cold-formed with a coarse thread and an asymmetrical thread section that forms a strong grip in the base material. The screw has a Sormat Nano surface treatment that ensures wide-ranging application conditions. The screw is fully removable and suitable for indoor, outdoor, and industrial use. The Sormat Nano surface treatment has been tested and approved by the Swedish certification authority for corrosion class C4. The screw is equipped with a pointed tip. The lightweight concrete screw is designed for through-installation into porous substrates such as blocks. Installation steps: 1. Screw directly into the substrate. Pre-drilling is generally not required. 2. Prevent over-tightening by using a torque limiter or tightening the screw manually to the end. Minimum installation depth for lightweight concrete screws is 60 mm. No special tools are required, and no preset torque value is needed. Packaging size: 10 pieces. Packaging type: small pack. The screw has a partial thread with a thread length of 60 mm. Screw head: T30, head diameter: 12 mm. Suitable substrates: lightweight concrete block, hollow lightweight expanded clay aggregate block, and solid lightweight expanded clay aggregate block. Thickness of material to be fastened: 30/10 mm.
