Product Description

Brief Overview

This 3/8-inch drive 12-point long hand socket delivers the extended reach and precision grip your technicians need for deep-set fasteners in confined spaces. The 12-point design provides six contact points per fastener rotation—reducing cam-out risk compared to 6-point alternatives—while the long body (63mm standard length) reaches fasteners that standard sockets cannot. Available in a complete 8mm to 24mm size range, these sockets integrate seamlessly with your existing 3/8-inch drive tool ecosystem. For versatility across fastener depths, consider pairing these with standard-depth sockets to cover both shallow and deep-access scenarios.

Key Features

• 12-Point Internal Profile: Enhanced grip geometry reduces fastener rounding and cam-out during assembly and removal
• Extended Length Design: 63mm body (standard) provides access to recessed or deep-set fasteners in tight quarters
• Precision Machining: Dimensionally accurate to European DIN standards; D1, D2, and T measurements ensure compatibility across drive systems
• Knurled Grip Band: Mid-body knurling improves hand control and prevents slipping during manual operation
• Satin Chrome Finish: Durable, corrosion-resistant coating suitable for workshop and field environments
• Comprehensive Size Coverage: 8mm through 24mm in single-size increments (17 sizes total)

Business Advantages for Resellers

Margin-Friendly Bulk Purchasing: Long-hand sockets are standard inventory in any professional shop. The 8–24mm range means technicians stock fewer SKUs while maintaining fastener coverage.

Repeat Demand: Hand sockets see steady replacement cycles due to wear, loss, or upgrade to larger kits. This is predictable inventory turnover.

Bundling Opportunity: Pair individual sizes with complete socket sets or cross-sell into impact-rated drive tools for upsell potential.

Universal Compatibility: 3/8-inch drive is the industry standard for mid-range fastening work. No niche market risk.

Specification Notes:

• L (Length): 63mm standard; ensures deep-socket access
• D1/D2: Socket body and drive interface dimensions; precision-engineered for alignment
• T (Thickness): Wall thickness increases with socket size for structural integrity

Application Profile

Primary Use: Reaching fasteners in engine bays, transmission housings, and recessed bolt locations where standard-depth sockets fall short.

Secondary Use: Precision assembly work where 12-point contact prevents fastener damage on soft metals (aluminum, brass) or damaged fastener heads.

Not Recommended For: Impact-driven applications (use impact-rated variants) or repeated hammer blows; hand operation or pneumatic wrench use only.

Value Statement

Stock these sockets in every size bracket—they're fundamental to professional fastening. The 12-point geometry and extended reach eliminate callbacks for stripped fasteners and stuck hardware. Order in bulk to secure wholesale pricing and build a loyal customer base of technicians who depend on reliable, accessible fastening solutions.
