The Lyman Pro Drive Torque Wrench (Model: LY-PDTW / MPN: 7031300) is a precision, click-type mechanical tool engineered for the exact installation and maintenance of firearm components. Operating within a range of 10 to 80 inch-pounds (in-lbs) and adjustable in precise 1 in-lb increments, this manual tool ensures that critical fasteners are tightened to exact manufacturer specifications. By applying precise torque, users can prevent common workshop mishaps such as stripped screw heads, damaged threads, and crushed optic tubes, while also ensuring consistent action-screw tension to improve rifle accuracy and shot-to-shot consistency.

Key Features:

• Audible and Tactile Alert: Features a mechanical slip and click mechanism that delivers a distinct physical and audible click once the preset torque limit is reached, preventing accidental over-tightening.
• Bidirectional Operation: Designed for versatility, this wrench can be operated in both directions, allowing users to both tighten and loosen fasteners.
• No Tension Release Required: The internal spring mechanism is engineered to store safely without needing to be wound back down to zero, maintaining its calibration accuracy over long-term use.
• Durable Construction: Built with a robust steel body, an ergonomic polymer handle with rubberized grip zones, and a knurled, anodized aluminum adjustment collar for slip-free setting.
• Comprehensive Accessory Kit: Includes a padded storage case, 10 firearm-specific drive bits, a 1/2-inch socket, a 1/4-inch socket adapter, and an individual calibration certificate verifying accuracy against ASME standards.

Product Specifications:

• Torque Range: 10 to 80 in-lbs (adjustable in 1 in-lb increments)
• Drive Size: Standard 1/4-inch hex drive
• Dimensions (Packaged): Approximately 12.2 inches L x 4.7 inches W x 2.7 inches H (31 cm x 12 cm x 6.9 cm)
• Weight: Approximately 1.55 lbs (0.7 kg)
• Power Source: 100% manual and mechanical (no batteries or 240V electrical power required)

For Australian gunsmiths and shooters, please note that while Australia primarily utilizes the metric system (Newton-meters), almost all major global firearm and optic manufacturers specify torque limits for scope rings, bases, and action screws in imperial inch-pounds (in-lbs). This makes the imperial scale on this wrench highly practical and standard for local workshop use. Additionally, because this is a purely mechanical hand tool, it does not require SAA or RCM electrical certifications, making it ready for immediate use on any Australian workbench.

Who It Is For:

The Lyman Pro Drive Torque Wrench is designed for Australian precision shooters, amateur and professional gunsmiths, and armorers who demand exactness when assembling and maintaining firearms. It is an essential tool for anyone regularly mounting scope bases, securing sensitive scope rings, or tightening action screws on precision chassis systems, where correct torque directly influences rifle harmonics and downrange accuracy.
