This micrometer-style torque wrench is built for mechanics, fabricators, and serious DIYers who need consistent tightening across a wide torque range. The tool combines a clear stamped scale, an easy-to-use locking feature, and a bi-material handle for better grip and comfort. It ships with a protective case for storage and transport and is manufactured to meet or exceed ASME specifications, giving you a reliable, traceable tightening instrument for automotive, industrial, and maintenance tasks.

How does this torque wrench ensure accurate settings?

The CRAFTSMAN torque wrench uses a micrometer adjustment mechanism and permanently stamped inch/metric scales on the housing so you can set target torque precisely. A locking feature secures the setting to prevent accidental changes while you work.

• Micrometer-adjustable throat for fine increments
• Stamped inch and metric scales for quick reference
• Locking collar prevents drift during use
• Calibrated to meet or exceed ASME standards

What torque range and drive size does it cover?

This wrench features a 1/2" drive and covers 50–250 ft-lb (68–339 Nm), making it suitable for medium to heavy-duty fasteners. It’s ideal when a single tool must handle a variety of torque specifications without frequent tool changes.

• Drive size: 1/2" for standard sockets
• Torque range: 50–250 ft-lb (68–339 Nm)
• Covers many automotive and machinery fasteners
• Eliminates need for multiple torque tools in many jobs

How comfortable and durable is the wrench for repeated use?

A bi-material handle improves ergonomics and reduces hand fatigue during extended tasks, while a rugged metal housing and included hard case protect the tool during transport and storage. The overall build supports workshop and field use.

• Bi-material handle for improved grip and comfort
• Sturdy metal body built for repeatable application
• Durable carrying case included for storage and transport
• Locking mechanism designed for long-term reliability

How should I use and care for this torque wrench?

Set the desired torque using the micrometer scale, lock the adjustment, attach the correct socket to the 1/2" square drive, and apply torque until the wrench indicates the set value. Keep the wrench clean, store it in the case, and return it to its lowest setting after use to preserve calibration.

• Adjust to desired torque, then engage the lock collar
• Use only sockets on the 1/2" square drive; avoid cheater bars
• Store in the provided case and avoid dropping
• Have calibration checked periodically for critical applications

Who is this for: The CRAFTSMAN CMMT99434 is built for automotive technicians, equipment maintenance personnel, and serious DIYers who need a dependable 1/2" torque wrench with a broad range. If you require accurate, repeatable torque between 50 and 250 ft-lb and want a tool that’s comfortable to use, portable, and made to industry standards, this wrench is a practical, long-lasting choice. It’s not intended for precision micro-torque work below 50 ft-lb, but it covers most medium and heavy fastening tasks encountered in garages, repair shops, and construction maintenance.
