The FACOM 40.1P5/16L is an industrial 1-5/16 inch Extra-Long, High-Torque Combination Wrench from FACOM's classic heavy-duty lineup.
- The Size: The fractional designation "1P5/16" translates directly to a standard 1-5/16" SAE width-across-flats. This size is commonly used in industrial plant maintenance, heavy structural steel fabrication, and fleet hydraulics.
- The Suffix: The legacy single L (Série Longue) and the modern LA codes refer to the exact same physical wrench, signifying an elongated handle shank engineered explicitly to optimize manual breaking leverage.
Core Engineering Specifications
- High Mechanical Advantage: Engineered specifically for breaking free frozen, over-torqued, or corroded fasteners. This long-pattern wrench features an extended profile that maximizes user leverage without necessitating the use of a cheater bar or pipe extension.
- OGV® 12-Point Profile: The closed ring end utilizes FACOM's patented OGV profile geometry. Instead of exerting crushing pressure directly onto the weak corners of a large hex bolt or nut, the internal walls grip across the larger flat sides. This drastically minimizes the risk of catastrophic fastener rounding.
- 15-Degree Hand Clearance: Both the open-jaw fork and the 12-point box eye are pitched at a precise 15-degree offset tilt. This critical clearance angle allows the tool to easily bypass obstructions and protects knuckles from impacting flat surrounding steel structures during heavy torque sweeps.
- Industrial Build & Finish: Forged from high-grade structural tool steel alloys and treated with a uniform Electro Chrome coating to provide clean hand manipulation and absolute protection from industrial oils, shop chemicals, and rust.
History of the Facom High Torque Long Combination Wrenches
1. The Genesis: The 'L' Variant (1980s) - The core structural architecture of this extended, heavy-duty industrial wrench family made its official debut in the early 1980s. The "L" suffix signifying Série Longue. This series was introduced to provide industrial field technicians with extended I-beam handles capable of pushing extreme manual breaking torque on heavy equipment fasteners without twisting. These wrenches were made in France and the country of origin was proudly displayed (cast) on the tool.
2. The Modern Shift: The 'LA' Suffix Debut (Late 1990s) - The precise "LA" revision designation debuted between 1998 and 2000. This suffix arrived during a company-wide modernization of FACOM’s inventory and manufacturing protocols. While the lengths and specs were consistent from one series to the next, the "A" update marked a subtle refinement to the forging tolerances and optimization for modern digital asset management. It was during this late 1990s window that FACOM actively migrated part numbers on the physical tool stamp from "L" to "LA". Production under Stanley ownership was moved to Taiwan. The LA series have a satin chrome finish and laser etched markings.
3. The Phase-Out Era (Late 2010s) - The fractional sizes of the extra-long 40.LA family enjoyed a long manufacturing run, but they were systematically phased out and discontinued by the late 2010s. As FACOM scaled back on niche SAE tooling to consolidate manufacturing efforts around their standard metric lines and high-performance 440 series aerospace wrenches, the fractional sizes in the 40LA series disappeared. The 40LA wrenches are still available in metric sizes from 19mm up to the massive 65mm size (a 33", 6kg/13.2 lb wrench).
