Slotted Screwdriver Bit, 0.5 x 5.5 x 25mm, 1/4" Hex Shank

Brief Overview

This is a precision-engineered slotted screwdriver bit designed for use with 1/4" hex chuck electric drivers and screwdrivers. The 0.5 x 5.5 x 25mm specification targets fine-to-medium slotted fastening work, making it ideal for assembly lines, precision electronics, and light industrial applications. Stock this alongside narrower slot variants and thicker gauge alternatives to cover the full spectrum of your customers' slotted fastener needs.

Key Features

• Precision Slot Geometry: 0.5mm thickness × 5.5mm width ensures perfect engagement with matching slot fasteners
• 1/4" Hex Shank: Direct compatibility with standard electric drivers and impact-rated chuck systems
• Compact 25mm Length: Ideal for shallow countersunk screws and confined assembly spaces
• Retention Groove: Grooved shank design improves bit retention in driver chucks, reducing drops and fastener damage
• Black Oxide Finish: Durable, corrosion-resistant coating designed for workshop durability and extended service life
• Tapered Tip Design: Slightly tapered geometry reduces cam-out and improves engagement consistency

Business Advantages for Resellers

• High-Volume Turnover: Slotted bits see consistent demand across light assembly, maintenance, and repair segments
• Bulk Order Opportunity: Offer complete slot-size ranges to single customers; this size pairs naturally with narrower (0.5×3mm, 0.5×4mm) and wider variants for tiered pricing
• Low Inventory Risk: Standardized 1/4" hex shank means one chuck type covers your entire bit portfolio
• Margin-Friendly: Excellent cost-to-revenue ratio on multi-unit orders; customers typically stock 5–10 bits per size
• Cross-Sell Potential: Bundle with longer 50mm variants for deep-well fastening work or thicker-slot bits for heavy-duty applications

Why This Matters to Your Customers

Precision bit geometry directly impacts fastener life and assembly quality. The 0.5mm thickness on this 5.5mm width combination is designed for fasteners that demand tight tolerances—electronics assembly, optical instruments, and precision machinery where cam-out causes screw damage and costly rework. The tapered tip and retention groove reduce bit slippage, lowering defect rates on automated and manual assembly lines alike.

Call to Value

Stock this bit in quantity to support the precision-assembly segment of your customer base. Its compact length and narrow slot make it indispensable for applications where standard 1/4" or 1/2" bits are too wide. Pair with complementary sizes for complete coverage, and position yourself as a trusted supplier of precision fastening solutions.
