Slotted Screwdriver Bit, 0.5 x 4 x 50mm, 1/4-Inch Hex Shank

Brief Overview

This slotted (flathead) screwdriver bit is engineered for professionals who demand reliable performance in precision fastening operations. The 0.5mm slot thickness and 4mm blade width make it ideal for small to medium-sized slotted fasteners, while the extended 50mm working length provides superior reach and leverage. The 1/4-inch hexagonal shank ensures compatibility with standard bit holders and impact-rated power tools. This is a workhorse bit for electronics assembly, automotive detailing, and general maintenance—pair it with smaller-profile slotted bits or longer-reach variants to build a complete slotted bit system.

Key Features

• Precision Slot Profile: 0.5mm thickness x 4mm width—matches OEM specifications for small to medium fasteners
• Extended 50mm Length: Provides reach into recessed areas and deeper fastening points
• 1/4-Inch Hex Shank (6.35mm): Universal fit with all standard power drill bit holders and manual holders
• Heat-Treated Steel Construction: Dark matte finish indicates hardened steel for durability and resistance to cam-out
• Magnetic Retention Groove: Built-in groove near the hex section for secure holding in magnetic or locking bit holders
• Tapered Blade Design: Smooth transition from shank to tip reduces stress concentration and prevents tip fracturing

Business Advantages for Resellers
