3/8-Inch Drive 11mm Machined Screw Socket

Brief Overview

This 3/8-inch drive socket is engineered specifically for fasteners with machined or damaged bolt heads. The precision-machined internal geometry provides secure engagement with compromised fasteners, reducing slip and cam-out. If you work with worn or stripped fasteners regularly, pair this with extractors for larger damaged bolts to cover your full fastener removal range.

Key Features

• 3/8-Inch Drive: Standard quarter-inch square drive compatibility with all professional socket sets and ratchets
• 11mm Nominal Size: Targets metric fasteners commonly found in automotive, machinery, and industrial assembly
• Machined Bolt Head Design: Internal spline or lobe profile grips damaged, rounded, or worn fastener heads more effectively than standard sockets
• Precision Manufacturing: Tight tolerances ensure consistent engagement and minimize rounding during removal
• Durable Construction: Built to withstand repeated impact and torque during fastener extraction

Why Resellers Choose This Product

Stock Gap Solution: The 11mm size fills a critical gap in standard socket sets, especially for mechanics dealing with European metric fastening standards.

Problem Solver: Damaged fastener extraction is a high-margin service. This socket enables your customers to remove problem fasteners without drilling or destructive methods—a premium service you can charge for.

Bulk Purchase Advantage: Mechanics and service shops typically need 2–3 units of specialized fastener removal tools. This drives multi-unit orders and repeat purchases.

Complementary Sales: Stock this alongside 10mm machined sockets and larger 12mm and 13mm variants to offer a complete stripped fastener solution.
