Impact Socket 1-Inch Drive, 43mm Hex, High-Depth Design

Brief Overview

This 43mm impact socket represents a critical size for suspension work, large fastener removal, and heavy-duty maintenance tasks. Designed specifically for 1-inch drive impact tools, the high-depth profile ensures optimal engagement with larger hex heads while distributing torque more evenly across the fastener. The thick-walled construction absorbs shock loads without deformation, making it a workhorse in any professional shop. For shops stocking impact socket kits, this size pairs naturally with smaller hex sockets like the 34mm variant and larger companions such as the 46mm option to cover the full range of common fastener sizes.

Key Features

• Six-Point Hex Design: Minimizes cam-out and protects fastener corners from rounding, critical for reusable fasteners
• High-Depth Profile: Extended length (68mm) reduces angle stress on fasteners and improves leverage control
• 1-Inch Square Drive: Compatible with professional-grade 1-inch impact wrenches and socket bars
• Matte Black Impact-Rated Finish: Provides corrosion resistance and identifies the tool as impact-capable at a glance
• Retention Hole: Built-in detent pin groove prevents accidental socket drop during tool changes
• Chamfered Edges: Reduces binding during insertion and removal from fasteners

Why Resellers Stock This Size

The 43mm socket occupies a sweet spot in the suspension and drivetrain category—too large for standard 3/8-inch drives but essential for 1-inch impact work. Shops replacing wheel bearings, suspension components, and transmission bolts require this exact size regularly. By stocking it alongside complementary sizes (32mm through 46mm), you position yourself as a complete supplier rather than a parts picker. Bulk ordering of high-demand sizes like 43mm improves margins while ensuring your customers never experience downtime searching for the right socket.

Why This Socket Matters for Your Inventory

Impact sockets rated for 1-inch drives command consistent demand in professional shops. The 43mm size specifically handles fasteners common in truck suspension, agricultural equipment, and industrial machinery. Unlike smaller sockets that wear quickly or larger sockets with limited application, 43mm achieves high turnover with minimal returns. Shops that trust your supply chain for these mid-range sizes often reorder the entire impact socket line, creating predictable bulk order opportunities.

Stock this size with confidence—it's not a specialty tool, it's a professional necessity.
