5mm Hex Impact Socket, 1/2" Drive, 78mm Extra-Long Deep Socket

Brief Overview

This 5mm hex impact socket delivers reliable performance for precision fastener applications requiring deep reach and consistent torque delivery. The 78mm extra-long design provides superior access in confined spaces, while the 1/2" square drive integrates seamlessly into standard impact driver systems. Whether you're stocking a general-purpose impact set or building specialized kits, this socket bridges the gap between larger 6mm hex sockets and premium metric collections—making it an essential inventory item for distributors serving automotive assembly, machinery maintenance, and precision engineering shops.

Key Features

• 5mm Hex Bit Design – Precision fit for M4 and M5 fasteners with minimal cam-out risk
• 78mm Extra-Long Depth – Reaches recessed fasteners without extensions
• 1/2" Square Drive – Compatible with all standard 1/2" impact drivers and torque-rated sockets
• Impact-Rated Construction – Matte black oxide finish resists corrosion and identifies tool as impact-safe
• Thick-Walled Socket Body – Absorbs reactive torque without deformation or premature wear
• Retaining Pin Hole – Side hole for optional detent pins; keeps socket secure during operation

Business Advantages for Resellers

Inventory Turnover: Small hex sockets move quickly in precision assembly environments. This size sits in the middle of the metric range, so stocking depth here captures both routine maintenance and specialized job requirements.

Margin Opportunity: Impact-rated hex sockets command premium pricing over standard sockets due to their durability and application specificity. Low production costs + high perceived value = strong distributor margins.

Customer Loyalty: Mechanics and assembly techs trust metric hex sockets that don't round or slip. Repeat orders from shops that depend on consistent tooling.

Bundle Potential: Pair with larger 8mm and 10mm impact hex sockets to create complete metric impact kits that appeal to automotive and industrial distributors.

Why This Socket Matters to Your Customers

The 5mm hex size is the workhorse of precision fastening. It's too small to ignore and too common to stock carelessly. This impact-rated socket won't deform under pneumatic torque, ensuring repeatable results across high-volume production runs. The extra-long 78mm design eliminates the need for extension bars in most applications—saving time and reducing tool breakage costs.

Stock this 5mm hex socket as a non-negotiable baseline in any metric impact collection.
