17mm Impact Hex Socket, 1/2" Drive, Extra Long 75mm Deep, CR-MO

Overview

This is a heavy-duty impact hex socket designed for professional mechanics and technicians working with high-torque fastening applications. The 17mm hex bit paired with an extra-long 75mm depth makes it suited for recessed or deep-set fasteners on industrial equipment, automotive work, and construction machinery. Built in chromium-molybdenum steel with a black protective finish, it delivers the durability needed for repeated impact use.

If you stock impact socket systems, consider pairing this with smaller metric hex sockets and larger format impact bits to offer a complete size range to your customers.

Key Features

• 17mm Hex Drive – Standard metric size for industrial fasteners
• 1/2" Square Drive – Compatible with all 1/2" drive impact tools and extensions
• Extra-Long 75mm Depth – Reaches deeply recessed or countersunk fasteners
• CR-MO Steel Construction – Chromium-molybdenum alloy withstands repeated impact stress
• Detent/Retention Hole – Locks securely to power tool drive end, preventing accidental disengagement
• Black Protective Finish – Corrosion resistance and professional appearance
• Chamfered Hex Edges – Reduces corner rounding and improves fastener grip

Business Advantages

Margin & Demand: Heavy-duty impact hex sockets command consistent demand in professional shops. The 17mm size is commonly requested for truck, construction, and industrial equipment work—high-frequency applications that justify bulk stocking.

Customer Retention: Impact sockets wear and break under real-world load. A 17mm hex socket that survives repeated 479.61 Nm impacts builds customer loyalty and repeat orders. One socket replacement call often leads to additional socket purchases.

Compatibility: 1/2" drive is the professional standard across impact wrench lines. This socket integrates seamlessly into existing tool ecosystems, making it an easy upsell to shops already buying air impact tools and socket sets.

Typical Fasteners: 17mm bolts and nuts on engine blocks, suspension components, coupling fasteners, and structural connections rated for sustained impact delivery.

Tool Compatibility: All 1/2" drive pneumatic impact wrenches, electric impact drivers (1/2" capacity), and manual breaker bars with 1/2" square drive.

Value Proposition for Resellers

This socket delivers on three fronts: it performs under genuine industrial load, it's built for longevity in high-impact environments, and it's a consumable-adjacent tool that generates repeat orders. Stock depth and the robust 479.61 Nm rating mean customers will trust it for their toughest jobs—and return when it needs replacement after extended service.

The extra-long 75mm design differentiates it from basic socket sets, positioning it as a premium offering for shops that demand precision and durability over commodity pricing.
