AERATED CONCRETE SCREW KBRM 10,5X210 FLANGE HEAD TX40 C4

Easy and fast-to-use Sormat long lightweight concrete screw KBRM 10.5 with low dome head and Torx drive. The carbon steel screw is cold-formed with a coarse thread, featuring an asymmetrical long threaded section that forms a secure thread in the base material. The screw has Sormat Nano surface treatment, ensuring wide operating conditions. The screw is fully removable. Suitable for indoor, outdoor, and industrial use. The Sormat Nano surface treatment has been tested and approved by a Swedish certification body 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 concrete blocks. Installation steps: 1. Screw directly into the substrate. Pre-drilling is generally not required. 2. Prevent over-tightening by using torque control or tightening the screw fully by hand. Minimum installation depth for lightweight concrete screws is 160 mm. No special tools required, no predefined 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 lightweight concrete screw has a partial thread with thread length of 160 mm. Screw head T40, head diameter 21.5 mm, head height 3.2 mm. Suitable substrates: lightweight concrete block, lightweight aggregate block with hollows, and solid lightweight aggregate block.
