Slotted Screwdriver Bit, 0.5 x 4 x 25mm, 1/4-Inch Hex Shank

Brief Overview

This precision-engineered slotted screwdriver bit is designed for professional-grade fastening in assembly, maintenance, and repair operations. The 0.5mm blade thickness paired with a 4mm blade width targets small to medium slot fasteners with tight tolerance requirements. The 1/4-inch (6.35mm) hexagonal shank integrates seamlessly with hex-drive screwdriver handles and quick-change chucks, enabling rapid bit swapping on production lines and in field service scenarios. Stock this size alongside narrower slot alternatives and extended-length variants to build a complete fastening solution for your customer base.

Key Features

• Precision Blade Profile: 0.5mm thickness ensures accurate fit without cam-out or tip deformation in precision slots
• 4mm Blade Width: Optimal for small electronic components, precision instruments, and miniature assemblies
• 1/4-Inch Hex Shank: Universal compatibility with standard hex-drive screwdriver handles and pneumatic/electric bit holders
• 25mm Overall Length: Compact profile suitable for confined spaces and compact assembly tools
• Milled Construction: Visible milling marks indicate precision machining; engraved markings prevent tool mix-ups on job sites
• Matte Metal Finish: Durable, non-reflective surface reduces glare during precision work

Business Advantages for Resellers

• High-Volume Demand: Slotted bits remain essential in electronics manufacturing, vintage appliance repair, and precision instrument assembly—consistent reorder category
• Margin-Friendly Pricing: Lower production cost than specialty bits allows competitive wholesale pricing with healthy distributor margins
• System Building: Customers purchasing one size typically need 3–5 complementary sizes; cross-sell widthwise variants and longer bits for deeper slots to increase average order value
• Professional Endorsement: Precision dimensions appeal to tool professionals who specify by exact slot width—builds reputation for accuracy in your product range
• Consumable Velocity: Small bits wear and break regularly in production settings, ensuring repeat purchases and predictable inventory turnover

Professional Recommendation

Stock this bit size as part of a tiered slotted-bit assortment. The 0.5 x 4mm profile occupies a critical gap in micro-fastening—larger than the tiniest watch screws but smaller than general-purpose automotive slotted bolts. Pair it with your medium-slot options to address the full spectrum of precision assembly applications your customers encounter.
