Description

1/2-Inch Drive Spline Bit M8, 800mm Length, Cr-V Steel

Overview

This 800mm long spline bit socket delivers precise fastener engagement for M8 applications requiring extended reach. Engineered from high-quality chromium-vanadium steel, it's designed for manual pneumatic and electric tool use where consistent torque transfer and secure bit retention are essential. The extended length makes it ideal for recessed or hard-to-access fasteners, while the M8 spline profile ensures positive engagement without cam-out risk. Stock this product alongside 1/2-inch drive alternatives in varying configurations and complementary M12 spline options to build a complete fastening solution for your customer base.

Key Features

  • M8 Multi-Spline Profile: Engineered to prevent rounding and ensure positive fastener engagement with minimal slippage.
  • 1/2-Inch Drive Socket: Standard female-style square recess compatible with 1/2" drive tools and power equipment.
  • Extended 800mm Shaft: Provides the reach necessary for recessed, deep-set, or restricted-access fastener applications.
  • Cr-V Steel Construction: High tensile strength and fatigue resistance ensure durability under sustained manual and pneumatic use.
  • Matte Black Finish: Professional appearance with corrosion-resistant surface treatment for workshop and field environments.

Business Advantages for Resellers

  • High-Margin SKU: Long-shaft bits command premium pricing due to specialized manufacturing and material costs.
  • Niche but Essential: Extended-reach configurations address a specific customer segment (automotive technicians, industrial assembly, HVAC installation) with limited alternative sourcing.
  • Bulk Order Opportunity: Stock this alongside standard-length alternatives to offer customers modular fastening solutions—increasing average order value.
  • Professional Perception: Positioning as a specialty spline bit supplier builds credibility with serious tool buyers.

Why This Product Works for Your Customers

Technicians working on confined assemblies—engine bay work, cavity fastening, or deep-set industrial bolts—frequently encounter situations where standard bit sockets fall short. This 800mm extension eliminates the need for improvised extensions or expensive custom solutions. The spline profile guarantees secure engagement, reducing rework and fastener damage that directly impacts profitability on labor-intensive jobs.
