1/2-Inch Drive Universal Joint, 40mm Length, Chrome Vanadium Steel

Brief Overview

This chrome-vanadium universal joint delivers the angled socket access your technicians need for confined spaces. The 40mm compact length positions it as an essential tool for engine bay work, transmission assembly, and situations where standard extensions won't fit. Pair it with larger drive universal joints for a complete socket system across multiple drive sizes.

Key Features

• 1/2-Inch Square Male Drive – Direct compatibility with standard 1/2" ratchets, impact wrenches, and breaker bars
• Chrome Vanadium Steel Construction – Hardened material resists fatigue and provides extended service life
• 40mm Compact Length – Ideal for restricted access applications where space is at a premium
• Swivel Joint with Pivot Pin – Allows angular articulation up to approximately 25°, enabling work at severe angles
• Spring-Loaded Detent Ball – Secures sockets firmly to the male drive, preventing accidental disconnect during operation
• Bright Chrome Plating – Corrosion resistance and professional appearance; easy to inspect for wear

Business Advantages for Resellers

• High-Demand Specification – Universal joints are wear items in busy shops; repeat orders are predictable
• Compact Size Drives Upsells – Technicians who need angled access typically purchase extension sets alongside this joint
• Margin-Friendly Pricing – Strong wholesale margins on industrial hand tool accessories
• Essential for Multi-Drive Inventories – Shops that stock 3/8" and 1/2" drive tools must have universal joints in multiple lengths

Why This Specification Matters

At 40mm, this joint fills a critical gap between rigid extensions and longer universal joints. Technicians working in engine bays—where exhaust manifolds, alternators, and transmission pans create spatial conflicts—rely on compact joints to maintain torque control while working at angles. Unlike longer 50mm+ joints that create leverage issues in tight spaces, this 40mm length preserves socket control while enabling the pivoting access that tight work demands.

The chrome-vanadium construction handles both hand ratchet work and pneumatic impact sequences, making it suitable for shops running mixed tool ecosystems.

Stock and Distribute with Confidence

Universal joints represent predictable, recurring revenue for distributors. This 40mm specification addresses a specific market need—compact engine bay access—without competing with your larger automotive socket extensions in the catalog. Recommend it as a primary tool for detailed assembly work and a complementary item for shops purchasing full socket sets.
