Flat Impact Screwdriver EPM E-400-0365, Hex 8 x 200 mm

The EPM E-400-0365 flat impact screwdriver features an 8 mm hex shank and a 200 mm blade length designed for delivering controlled percussion torque to flat-head fasteners. Built for tasks where screws are seized, rusted, or require extra force to release, this tool combines a solid hex shank with a long blade to reach recessed screws and permit use with standard impact tools or strike action with a hammer. Materials and construction focus on durability and reliable transfer of impact energy to the screw head.

Advantages

The solid hex 8 mm shank ensures secure seating in chucks and impact adapters and resists rounding under high torque. The 200 mm blade provides extended reach into tight or recessed areas while maintaining rigidity for effective torque transfer. Its design converts hammer strikes into rotational force suited for loosening stuck flat-head screws, reducing the risk of cam-out when used correctly. The tool is suitable for repeated use in workshop, automotive and maintenance environments thanks to a robust build.

Suitable for

• Automotive repairs where rusted or seized flat-head screws need percussion torque
• Maintenance and servicing of machinery and equipment with recessed flat-head fasteners
• Assembly and disassembly tasks in workshops requiring impact screwdriver use
• Situations that require use with impact adapters, impact drivers, or hammer strikes

Key specifications

• Tip type: flat (slotted) screwdriver tip sized for compatible flat-head screws
• Shank shape: hexagonal, 8 mm across flats for secure engagement
• Blade length: 200 mm for extended reach
• Drive method: impact (percussion) transfer suitable for hammer strikes or impact tool adapters
• Construction: hardened steel components designed for impact use

How to use

Place the flat tip into the screw slot, ensuring a correct fit to minimise slipping. Secure the hex shank in an impact adapter, impact driver, or hold the handle and strike the end with a hammer to deliver short, controlled impacts while applying rotational pressure. Start with firm but controlled blows and increase force as needed, turning the screwdriver between strikes if required. After the screw begins to turn, continue with steady impacts until fully loosened or tightened. Inspect the screw slot for damage and choose a replacement fastener if the slot is excessively worn.

Usage recommendations

Use appropriate eye protection and gloves when applying percussion torque. Match the tip size to the screw slot to reduce cam-out and avoid excessive force that can damage fasteners or the tool. For electrical work, ensure circuits are de-energised before use. Store the tool in a dry workspace to prevent corrosion and periodically check the tip and shank for wear or deformation.
