10mm Hex Driver Bit, 4-30mm

Brief Overview

This is a precision-engineered hex driver bit designed for 10mm hex sockets, with an overall length of 30mm and a 4mm hex tip. Manufactured from S2 steel with a dark-oxide finish for corrosion resistance, this bit delivers reliable performance in demanding fastener applications. For shops requiring additional precision options, consider pairing this with smaller hex tips like 5mm or 6mm variants to cover a broader range of fastener sizes.

Key Features

• Hex Tip Size: 4mm
• Shank Diameter: 10mm (standard hex socket compatible)
• Overall Length: 30mm
• Material: S2 steel (impact-grade tool steel)
• Finish: Dark-oxide treatment for corrosion and wear resistance
• Precision Machining: Radiused transition between shank and tip reduces stress concentration
• Professional Grade: Stamped size marking for quick identification and inventory control

Technical Advantages

Fastener Compatibility: The 4mm hex tip accommodates small precision fasteners commonly found in electronics assembly, light machinery, and precision instrument work. The 10mm shank integrates directly with standard hex socket drives, eliminating the need for adapters.

Durability & Reliability: S2 steel offers exceptional impact resistance without brittleness, making this bit suitable for both hand-tool use and power-tool applications. The dark-oxide finish protects against corrosion in humid or wet shop environments.

Precision Fit: The machined hex geometry ensures minimal wobble and reduces the risk of fastener rounding, critical for maintaining customer satisfaction in precision assembly work.

Business Advantages for Resellers

• High-Margin Accessory: Hex bits are essential consumables with excellent repeat-order potential
• Bulk Order Economics: Stock multiple tip sizes (including 6mm and larger variants) to build a complete hex bit system for your customers
• Professional Positioning: S2 steel grade signals durability to your clientele; position this as the premium option over lower-grade alternatives
• Low Carrying Cost: Compact, lightweight inventory that occupies minimal shelf space while generating consistent sales velocity
