The Flat Slotted Screwdriver (5mm x 100mm) is a professional-grade hand tool engineered for precision mechanical assembly, electrical terminal tightening, control panel wiring, and general maintenance. Constructed from premium heat-treated Chrome Vanadium (Cr-V) / S2 alloy steel with a hardened magnetic black-oxide slotted tip, this screwdriver delivers exceptional torque transfer, slip resistance, and long-term durability. Its ergonomic, high-torque dual-material grip ensures comfortable, fatigue-free operation during prolonged electrical and mechanical work.

Features

• Strong Magnetic Tip: Securely holds screws in place for easy one-handed starting and retrieval in tight or recessed spaces.
• Hardened Cr-V Steel Shank: Delivers superior torsional strength and resists bending, twisting, or rounding off under high rotational torque.
• Precision-Ground Slotted Tip: Precision-machined 5mm tip ensures a snug, gap-free fit into screw slots, significantly reducing cam-out and preventing screw head damage.
• Ergonomic Non-Slip Grip: Contoured dual-material handle provides maximum hand comfort, slip resistance against oily hands, and excellent torque transfer.
• Corrosion-Resistant Coating: Satin chrome blade with black phosphate tip protects against oxidation, rust, and chemical exposure in workshop environments.

Common Applications

• Electrical Wiring & Terminal Blocks: Fastening standard screw terminal blocks (e.g., KF series, DIN-rail connectors, circuit breakers, and distribution boards).
• Electronics Assembly & Repair: Prototyping, chassis assembly, power supply casing, and equipment maintenance.
• Automotive & Machinery: General-purpose mechanical fastener tightening and adjustment in tight engine bays or control boxes.
• Industrial Control Panels: Field wiring for contactors, relays, timers, and PLC I/O terminals.
• DIY & Workshop Projects: Essential tool for 3D printer building, robotics assembly, and household appliance repair.

Usage Tips

• Slot Matching: Always ensure the 5mm tip matches the screw slot width and depth properly to avoid stripping the screw head or burring the screwdriver tip.
• Non-Insulated Handle Precaution: Unless explicitly rated for 1000V VDE use, always disconnect mains power before using the tool on electrical panels and wiring.
• Avoid Prying: Use the screwdriver strictly for rotational fastening; do not use the tip as a heavy-duty chisel or pry bar to preserve tip geometry.
• Maintenance: Wipe down the shaft and tip with a light anti-rust oil after use in damp environments to maintain the finish and magnetic strength.
