7-Piece Stud Puller Wrench Set with Barrel Cam Mechanism

Brief Overview

This seven-piece stud puller set delivers precise, non-damaging extraction and installation of studs across multiple automotive and industrial applications. The barrel cam mechanism—controlled by internal rollers—grips studs securely without stripping threads, making it an indispensable addition to any shop's fastener-removal inventory. Whether you're servicing engine blocks, suspension components, or transmission housings, this set addresses the core problem: removing damaged or seized studs without collateral damage. Complement this with drive shaft extraction tools for comprehensive drivetrain service capability.

Key Features

• Barrel Cam Grip Technology: Internal roller-controlled mechanism provides consistent, thread-safe engagement without cam-out or rounding
• 7 Metric Socket Sizes: Covers 5mm through 14mm studs in commonly required configurations
• Chrome Polished Finish: Corrosion-resistant, professional appearance; easy to inspect for wear
• Knurled Grip Collars: Secure hand control during manual operation or power-tool use
• Dual Drive Compatibility: Square/hex drive ends accommodate both 3/8" and 1/2" ratchets and impact wrenches
• Organized Blue Molded Case: Individual cavities protect sockets and streamline workshop organization

Why Resellers Choose This Set

Margin-Friendly Entry Point: Stud extraction is a specialized service that commands premium labor rates. Your customers will justify the investment quickly with the first stuck stud job.

Repeat Order Potential: Shops performing regular engine rebuilds, transmission service, or suspension work will purchase consumables (gaskets, seals, fasteners) alongside this tool, increasing ticket value.

Differentiation & Credibility: Professional shops distinguish themselves by having purpose-built extraction tools. This signals competency to end customers and justifies higher service fees.

Minimal Training Required: The barrel cam design is intuitive—even apprentices understand "thread-safe grip" immediately, reducing support burden.

Specifications Detail

Drive Configuration: The set splits across two drive sizes—3/8" for smaller studs (5mm) and 1/2" for mid-range (6–12mm) and pin applications (14mm). This dual-drive approach accommodates both light fastener work and heavier automotive service without requiring adapter sleeves.

Barrel Cam Operation: Unlike crude slip-on sockets, the controlled roller mechanism prevents the common failure mode of stud extraction—the socket slipping and rounding the stud head. This is particularly valuable when working with corroded, damaged, or partially stripped studs where traditional sockets fail.

Size Coverage: The 5mm-to-14mm range addresses the majority of automotive fastener extraction work: engine block studs, cylinder head applications, transmission bell housing bolts, and suspension component fasteners. The 14mm pin socket bridges to common dowel and alignment pin removal.

Value for Your Bottom Line

This set solves a recurring customer pain point—extracting stuck or damaged studs without destroying the surrounding component. A single successful extraction that would otherwise require boring out and helicoil repair justifies the entire kit investment. Stock this alongside adjustable wrench solutions for comprehensive fastener service coverage.

Professional shops performing engine rebuilds, transmission overhauls, or suspension refurbishment will return to this set repeatedly, making it a stable SKU in your catalog and a reliable margin driver for your business.
