1/2-Inch Drive Extension Bar, 75mm Chrome Vanadium Steel

Brief Overview

This 75mm extension bar fills a critical gap in any 1/2-inch drive socket kit, offering the shortest reach option for confined or tight work spaces. Chrome vanadium construction ensures durability and corrosion resistance in professional shop environments. The detent ball mechanism keeps sockets firmly seated during use, while the polished finish maintains professional appearance through years of service. For distributors stocking complete drive systems, pair this with longer 250mm extensions to cover the full working range your customers need.

Key Features

• Compact 75mm Length: Ideal for restricted access areas, tight engine compartments, and precision fastening work
• Chrome Vanadium Material: Stamped directly into the shaft for guaranteed material specification and durability
• Detent Ball Locking: Secure socket retention prevents accidental separation during operation
• Female 1/2" Square Recess: Accepts any standard 1/2-inch drive socket
• Male 1/2" Square Drive: Connects to ratchets, torque wrenches, or breaker bars
• Polished Chrome Finish: Bright, corrosion-resistant plating resists rust and maintains resale appearance
• Grip Grooves: Shallow longitudinal grooves on the female end aid handling and socket alignment

Business Advantages for Resellers

Stock Essentials, Not Redundancy: This 75mm size targets mechanics who work in confined spaces—engine bays, steering columns, electronics enclosures. It's a genuine gap-filler, not a product category duplicate.

Turnover Driver: Short extensions are high-velocity items because they're frequently misplaced or left at job sites. Customers will reorder regularly.

Margin Stack Opportunity: Bundle with standard sockets and ratchets. A mechanic buying a 75mm extension typically needs a complete socket set nearby—natural cross-sell into higher ticket items.

Professional Presentation: Chrome vanadium branding and polished finish signal quality to end customers. No cheap feel, no objections to price point.

Why This Extension Matters

In professional garages, the 75mm extension bridges the gap between a ratchet and a socket in tight quarters. Unlike longer extensions that require more leverage and create alignment issues in confined spaces, this compact bar provides just enough reach without sacrificing control. The detent ball is non-negotiable—it prevents sockets from dropping into engine bays or transmission pans during hot service work.

Chrome vanadium construction isn't cosmetic; it's the industry standard for impact-capable tools. This extension will tolerate accidental impacts from pneumatic tools without cracking or bending, a real concern in busy shops.

Reseller Positioning

Position this as the "tight space specialist" in your catalog. Every shop has at least three mechanical situations where a standard ratchet-to-socket connection is impossible. Mechanics know this pain point—they'll buy when they realize you stock the solution.

Stock depth recommendation: For every torque wrench or breaker bar you sell, keep at least two of these extensions in inventory. Attach them to socket set bundles as a value add.
