14x18 mm Torque Insert Heads for Mid-Capacity Open-Head Torque Wrenches
Browse ConnexTool's 247-piece range of 14x18 mm torque insert heads — the most widely specified interchangeable insert-square size across professional torque wrench systems — from Stahlwille, Hazet, Wera, and Bahco. Covering torque capacities from roughly 40 Nm up to 420 Nm, this size class serves general automotive, machinery, and structural fastening work where a single calibrated 14x18 mm wrench body needs to accept dozens of different drive, spanner, and specialty tool profiles.
Reversible Ratchet Tooth Geometry, Metric & Imperial Head Profiles, and Size-Converter Adapters
Insert heads in the 14x18 mm class share a common rectangular insert-square that locks into any matching open-head torque wrench, decoupling the calibrated drive from the fastening tip. Reversible ratchet heads range from Hazet's 32-tooth 6404 series to Bahco's 45-tooth 14R and 60-tooth push-through 14T models — a finer tooth pitch means less swing arc needed to re-engage in tight bays, and quick-release variants like Bahco's 14Q let the head detach without removing the wrench from the fastener. Open-end and ring heads (Stahlwille's 731/731a and 732/732a series) are stocked across both millimetre and inch sizes to match metric or imperial fasteners directly, while dedicated Torx-profile heads (732TX) cover E-type screw geometries. Size-converter adapters such as Stahlwille's 7370/40 series step a 14x18 mm wrench up to the larger 24.5x28 mm interface for higher-capacity work, and weld-on spigot connectors (Stahlwille's 737 series, Bahco's 14W) let workshops fabricate custom tool heads for non-standard fasteners.
A Comprehensive Blueprint of 14x18 mm Insert Head Configurations
Our catalog spans every head profile available in the 14x18 mm insert-square size:
- ✔ Reversible & Quick-Release Ratchet Heads: Hazet 6404/6602 and Bahco 14R/14Q/14T series with 32 to 60 teeth, delivering up to 420 Nm across standard, low-profile, and push-through designs.
- ✔ Open-End & Ring Insert Heads: Stahlwille's 731/731a open-end and 732/732a ring series, available in both millimetre and inch sizes for direct metric or imperial fastener access.
- ✔ Torx & Self-Adjusting Heads: Stahlwille's 732TX series for E-type Torx screw geometries, plus Wera's self-adjusting Joker 3XL head covering a wide spanning range in one unit.
- ✔ Size-Converter & Weld-On Adapters: Stahlwille's 7370 series for stepping up to 24.5x28 mm interfaces, plus 737 and Bahco 14W weld-on spigot connectors for custom tool fabrication.
