1/4-Inch Drive Wobble Extension Bar, 400mm Length

Brief Overview

This 400mm wobble extension bar is purpose-built for 1/4-inch drive socket work where standard rigid extensions fall short. The offset wobble joint allows sockets to work at angles, significantly improving access to fasteners in confined spaces—a critical advantage over straight extensions. Whether you're working around engine components, tight corners, or recessed hardware, this length provides the reach your shop needs. For shops requiring multiple lengths, shorter wobble options and standard rigid extensions are available to cover all access scenarios.

Key Features

• 400mm Extended Reach – Bridges gaps that shorter extensions cannot, reducing the need for multiple tool swaps
• Wobble Joint Design – Flex joint at the drive end allows socket engagement at 45° angles, essential for angled fastener access
• Chrome-Plated Finish – Corrosion-resistant coating ensures durability in workshop and outdoor environments
• Knurled Grip Section – Textured mid-shaft grip improves control and reduces hand slip during torque application
• 1/4-Inch Drive Compatible – Works seamlessly with standard 1/4-inch drive sockets and attachments
• Machined Drive Ends – Precision-formed male and female drive surfaces ensure tight, consistent connections with zero play

Why This Matters for Your Business

Reduced Customer Callbacks – Customers can tackle multi-angle fastening jobs without returning tools, increasing customer satisfaction and repeat business.

Higher Perceived Value – The wobble feature justifies a premium over rigid extensions; customers recognize the practical difference immediately.

Increased Tool Set Completeness – Stocking both 400mm wobble and shorter 250mm extensions positions you as the comprehensive tool supplier, capturing full project sales rather than partial ones.

Margin Opportunity – Wobble extensions command better margins than standard rigid bars; bundling with socket sets increases transaction value.
