Screwdriver bit King Tony 102555S1 — slotted (flat) 5.5 mm

King Tony 102555S1 — slotted (flat) 5.5 mm is a compact screwdriver bit designed for use with manual and power screwdrivers that accept standard exchangeable bits. The 5.5 mm flat blade is intended for slotted (flat-head) screws commonly found in furniture fittings, light mechanical assemblies and electrical components. Made from S2 silicon chrome vanadium alloy steel and finished with an anti-rust oil and sand-blasted surface, this bit balances wear resistance with controlled hardness for frequent fastening tasks. Its total length of 25 mm makes it suitable for confined spaces where a longer bit would be impractical, while the lightweight construction (approx. 5 g) adds minimal weight to a bit set or portable toolkit.

Advantages

The use of S2 silicon chrome vanadium alloy steel provides improved toughness and durability compared with ordinary tool steels, helping the bit resist chipping under normal torque loads. The anti-rust oiled, sand-blasted finish reduces corrosion risk and improves grip during insertion and removal from bit holders. Conformance to the relevant slotted screwdriver standards ensures dimensional consistency for reliable engagement with matching screw heads. The compact 25 mm length and moderate blade width deliver a balance of accessibility and torque transfer for general fastening and maintenance work.

Suitable for

• Assembly and disassembly of furniture with slotted screws
• Light mechanical repairs and maintenance
• Electrical fittings and terminal work where slotted heads are used
• Portable bit sets for home, trade and field service tasks

Key specifications

How to use

Insert the King Tony 5.5 mm slotted bit into a compatible bit holder or quick-change chuck until it seats securely. Align the blade with the slotted screw head and apply steady axial pressure while turning the screwdriver or operating the driver. For power screwdriver use, select an appropriate torque setting to avoid cam-out or damage to the screw head. After use, wipe the bit clean of debris and store it in a dry bit organizer to preserve the anti-rust finish.

Usage recommendations

Use the 5.5 mm slotted bit for screws with matching slot widths to ensure proper engagement; avoid using excessive torque or impact on delicate screw heads. For prolonged work, rotate between bits to reduce wear and inspect tips for rounding or chipping, replacing the bit when deformation is visible.
