Flat-tip locksmith screwdriver Jonnesway D70S5100 5.5x100 mm

Jonnesway D70S5100 is a flat-tip locksmith screwdriver with a 5.5 mm blade width and a 100 mm blade length designed for manual fastening, light prying and precise adjustment tasks. The tool is intended for use in metalworking, mechanical assembly and general repair work where a controlled flat tip is required for slot screws and small-scale interventions. The screwdriver combines a straight steel blade with an ergonomic handle profile to provide controlled torque and accurate tip alignment during maintenance and installation jobs.

Advantages

The flat-tip design provides precise contact with slotted screw heads, reducing cam-out and wear on both fastener and blade. A 100 mm blade length offers reach into recessed screw locations while the 5.5 mm width matches common slot screw sizes used in locksmithing and mechanical assemblies. The durable steel blade maintains tip geometry under repeated use, and the handle shape supports a firm grip for controlled torque application.

Suitable for

• Loosening and tightening slotted screws in metal fittings
• Locksmith tasks requiring precise flat-tip engagement
• Mechanical assembly and maintenance of machinery
• General repair work and small prying or lever actions
• Electrical panel covers and fastening in equipment housings

Key specifications

• Blade width: 5.5 mm
• Blade length: 100 mm
• Tip type: flat / slotted
• Blade material: hardened steel (non-corrosive coating may vary by batch)
• Handle: ergonomic design for manual torque control
• Use: manual fastening, prying and precision adjustment

How to use

Select the Jonnesway flat-tip screwdriver when the slot width of the screw matches the 5.5 mm blade. Insert the tip fully into the screw slot to ensure even contact, then apply steady, controlled force while turning to avoid cam-out. For recessed screws, use the full 100 mm blade length to reach the fastener and maintain alignment between tip and screw head. Use the handle to control torque and avoid over-tightening; when prying, apply force gradually and ensure the surrounding material is protected to prevent damage.

Usage recommendations

Inspect the tip before use and replace the tool if the blade is deformed or excessively worn. Match the screwdriver size to the screw slot to minimize damage. Store the screwdriver in a dry place to reduce corrosion risk and avoid using the tool with power drivers or as a chisel to maintain blade geometry and safe operation.
