Adjustable Pin Wrenches for Top-Hole Nuts – Professional Set
Brief Overview
This is a specialized wrench set designed for fastening and removing nuts equipped with top holes—a common feature in precision engineering, automotive assembly, and industrial applications. The set includes two articulated chrome vanadium wrenches with interchangeable pins, allowing you to address multiple nut sizes without carrying separate tools. If your customers work with specialty fasteners regularly, this pairs well with universal groove and axle nut tools for comprehensive fastener coverage.
Key Features
- Two Double-Ended Wrenches: Articulated design with central pivot joint for improved access in confined spaces
- Interchangeable Pin System: 8 pins supplied per wrench; additional 2 spare pins included for continuity of service
- Size Coverage: Four working ranges—2.5–4mm, 3–5mm, 6–8mm, 7–9mm—addressing most common industrial top-hole nut sizes
- Chrome Vanadium Steel Construction: Forged for durability and resistance to deformation under load
- Central Knurl Adjustment: Divider-type mechanism allows precise, controlled pin positioning without tools
- Professional Carrying Case: Black molded plastic case with foam-lined cavities for organized storage and job-site transport

What This Means for Your Customers
Technicians working with specialty fastened components—fuel injectors, sensor clusters, or precision machinery—eliminate the frustration of cam-out or slipping caused by standard wrenches on top-hole nuts. The articulated design fits into tight engine bays and machinery frames where fixed wrenches cannot reach. The interchangeable pin system means they carry one tool instead of four separate wrenches, reducing toolbox weight and inventory costs.
