1/2-Inch Drive Extension Bar, 50mm Chrome Vanadium Steel

Brief Overview

This 50mm extension bar is a precision-engineered socket wrench accessory designed to extend your reach in confined spaces and tight work areas. The compact length makes it ideal for applications where socket head clearance is limited. Chrome vanadium construction ensures durability and corrosion resistance across heavy-duty automotive and industrial tasks. If you need additional reach options, consider pairing this with extended-reach socket bar variants or longer extension bars for more versatile coverage across your workshop inventory.

Shop & Mechanic Application

This extension bar is purpose-built for situations where a socket alone cannot reach the fastener. The 50mm length is compact enough to slip into spaces where 75mm, 125mm, or longer extensions would bind or be inaccessible. Common applications include:

• Engine assembly: Spark plugs, sensor ports, and tight valve cover areas
• Undercarriage work: Brake caliper bolts, suspension fasteners in cramped geometry
• Interior trim: Dashboard fasteners and component removal where space is at a premium
• Precision assembly: Any task requiring a short reach extension without bulk

Value Proposition for Distributors

The 50mm extension bar is a high-turnover SKU that professional mechanics and DIY shops purchase in sets or as replacement items. Its niche size means it's often missing from incomplete sets, creating demand for mid-range bulk orders. Chrome vanadium construction at this price point delivers exceptional value perception, encouraging customers to specify quality tools to their suppliers. Stock this alongside comparable socket extensions in 75mm to offer complete coverage and maximize order value.
