30 Pieces Concrete Screws M6 x 75 mm, Hexagonal Head Screws Set Without Plugs, Galvanized Screws with Washer for Industrial Masonry and Concrete Architecture

• 【High Strength Material】M6 concrete screws use high-strength carbon steel substrate and galvanized coating with high tensile strength, corrosion and oxidation resistance, making them suitable for humid, outdoor and industrial environments (such as factories and underground parking lots).
• No expansion tube: The special cutting groove on the screw tip can be cut directly into the concrete to form an internal thread with high gripping force, no need to pre-install expansion pipes and anchor bolts, which improves the efficiency of installation.
• Hexagonal design: Hex head screws use a solid design with a hex drive device and a washer, which increases the force bearing surface. Interaction with the external hex drive helps withstand high-torque impact drilling and prevents slippage or head deformation.
• Widely Used:Suitable for masonry, concrete, machinery, industrial construction, automotive transportation, electrical products, mechanical foundations, steel structure bridges, shelving anchoring and other applications that require vibration resistance.
• Box contents: You will receive 30 concrete screws M6 x 75 mm. No tensile stress, which avoids the risk of concrete cracking, making them especially suitable for reinforcing old buildings. They meet the requirements of use in multiple areas.
