AERATED CONCRETE SCREW KBRM 10,5X185 FLANGE HEAD TX40 C4

Attach wooden substructures, supports, frames, rims, and braces to lightweight concrete (Siporex) and lightweight expanded clay aggregate (Leca) without pre-drilling using a coarse-threaded lightweight concrete screw. Easy and fast to use Sormat long lightweight concrete screw KBRM 10.5 with a low-profile cup head and Torx drive. The carbon steel screw is cold-formed with a coarse thread and an asymmetrical long thread section that forms a secure thread in the base material. The screw features Sormat Nano surface treatment, ensuring wide operational 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 cutting spike tip. The lightweight concrete screw is designed for through-installation into porous substrates such as blocks. Installation steps: 1. Screw the 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 160 mm. No special tools are required, no preset tightening torque. The longer and thicker screw body enables deeper installation, improving grip in the substrate. The cutting tip of the lightweight concrete screw makes it self-tapping. Pack size: 30 pcs. The screw has a partial thread with a thread length of 160 mm. Screw head T40, head diameter 21.5 mm, head height 3.2 mm.
