3/8-Inch Drive 6-Point Long Hand Socket

Overview

This 3/8-inch drive 6-point long hand socket is engineered for mechanics and technicians who need reliable access to recessed or hard-to-reach fasteners. The elongated well design delivers the extra reach required in confined engine bays, suspension assemblies, and electrical housings. Available in 15 individual sizes from 8mm to 24mm, these sockets integrate seamlessly with standard 3/8-inch ratchets and extensions. For shops requiring complete coverage across multiple fastener sizes, complementary individual socket options are available to round out your toolkit.

Key Features

• 6-Point Design: Provides secure, non-slip engagement with hex fasteners; minimizes corner rounding and extends fastener life
• Long/Deep Profile: Extended well accommodates recessed bolt heads and tight spaces where standard sockets cannot reach
• Chrome Satin Finish: Durable, corrosion-resistant coating withstands workshop humidity and repeated use
• Knurled Grip Ring: Textured band on the socket body improves hand control and reduces slipping during manual tightening or loosening
• Square 3/8-Inch Drive: Female recess accepts all standard 3/8-inch ratchets, breaker bars, and pneumatic tools
• Blackened Bore: Interior machining darkens the fastener engagement surface, reducing glare and improving visibility into tight spaces
• Stamped Part Identification: Each socket is marked for easy inventory tracking and replacement ordering

Business Advantages for Resellers

• High Turnover Category: Long hand sockets are consumable-adjacent—mechanics stock multiples as backups or lose them in engine compartments
• Bulk Order Potential: The 15-size range encourages customers to purchase complete sets rather than single sockets
• Competitive Pricing: OEM specifications at distributor margins support healthy margins without premium branding
• Inventory Flexibility: Sell as individual units (SKUs 543608–543624) or bundle as assortments (8–12mm, 13–24mm ranges)
• Repeat Business Driver: Wear, loss, and damage drive replacement orders throughout the year

Application Context

These sockets excel in automotive engine work, suspension repair, and electrical assembly where fastener access is restricted. The 6-point design prevents cam-out on softer fasteners and reduces the likelihood of stripped bolt heads—a common cost driver in warranty claims. Mechanics routinely replace long sockets after loss or damage in confined spaces, making this a reliable reorder category.

Value Proposition

Stock this range to capture both immediate repair work and ongoing replacement demand. The 15-size lineup covers the vast majority of metric hex fasteners encountered in European and Japanese automotive applications, positioning your shop as a complete solution provider.
