Designed for Professionals C.K Tools delivers innovation trusted by tradespeople worldwide. The C.K Roofing Bolt Driver (T4561) is engineered for fast, reliable fixing of roofing bolts — combining precision fit, magnetic hold, and impact-rated strength for total control on-site. Optimised for Roofing Bolts Its unique 4-blade design provides an exact fit on roofing bolt heads, preventing rounding and ensuring consistent torque transfer — a key advantage over standard flat or Phillips bits. Magnetic Retention for Speed & Safety A Stronghold magnet holds the bolt or nut securely in place, ideal for M6 roofing bolts, wing nuts, and thumb screws, reducing the risk of dropped fasteners and saving time during installation. Impact Ready Construction Forged from S2 impact steel, this driver bit endures repeated use with cordless and mains-powered impact drivers. It delivers professional durability where standard bits fail. Quick-Change Compatibility The 6.35mm (¼") hex shank enables instant bit swaps in all standard quick-change systems, compatible with popular bit sets and roofing tools. Compact and balanced at 75mm, it’s perfect for overhead and confined spaces. Built for Roofing Professionals Ideal for roof fixing, cladding, structural frames, and general maintenance. The T4561 delivers reliability, accuracy, and strength that professionals depend on every day.
