Quality – another thing to look for is a tool with a solid body made of steel alloy. They will serve much longer; Dial Torque Wrench: Dial Torque Wrenches utilize a dial or gauge with a calibrated scale and rotating needle to display the applied torque and indicate the torque value applied. Show more The Expert: I’m a home improvement freelance writer with over a decade of experience in a variety of trades. I have used torque wrenches throughout my professional career in residential construction, as well as in my personal life working on vehicles. Most recently, I used my torque wrenches extensively while replacing the engine in my 1985 Ford F250. My work has appeared in Bob Villa, The Family Handyman, and The Spruce. Types of Torque Wrenches A range of up to 20 to 150 Nm is enough for small jobs. If you use a torque wrench more frequently – the range should be about 100-700 Nm. If you apply the force of 80 Nm, the tool should have the range from 20 to 150 Nm. The square head drive size Torque wrenches are most commonly available with ¼-, ⅜-, and ½-inch drives; the latter two sizes are the most popular and versatile for automotive applications. A ¼-inch drive is commonly found on power tools and works well on small engines (like landscape equipment) and plumbing and HVAC components.

On the other end of the tool, by the handle, a scale shows the current force being applied. This scale can be adjusted on some products to limit the maximum torque the wrench can apply. However, the deflecting beam torque wrench’s biggest benefit over the standard beam torque wrench is that it is more durable, allowing you to use it for a longer period without having to replace the tool. Split Beam Most precise torque wrenches have a range that reaches 150-foot pounds, which is more than enough to tighten lug nuts on your car. However, many torque wrenches have a much wider torque range, with some reaching 1,000 foot-pounds of force. Scale Readability To calibrate a torque wrench on your own, you will need a bench vise, a 20-pound weight, a thin rope or string (capable of holding at least 20 pounds), and a measuring tape. Digital torque wrenches come pre-calibrated for precise readings that are displayed on the digital screen. This style of torque wrench offers the most precise readings in the most straightforward format, but you cannot use the wrench if the batteries run out. Yes, all genuine Snap-on torque wrenches really have a lifetime warranty. It is a great feature if you seek a durable and affordable instrument that you plan to use occasionally.The torque wrench’s drive size describes the bits you can use to tighten nuts and other fasteners. The standard sizes include 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, and 1 inch, though you won’t be working with anything above a 1/2-inch drive for most applications.

The display on the torque wrench replaces the traditional scale, allowing you to set the torque level using the intuitive buttons on the handle. The handle is comfortable and ergonomic, allowing you to work for longer before feeling the effects of hand fatigue. This product also boasts an impressive torque range of 22 to 250 foot-pounds. The range of a torque wrench can limit the types of jobs you can perform if it is too small, so how much torque a wrench provides is very important. On average, a torque wrench with a range that falls below 100 foot-pounds is considered ineffective for most automotive and mechanical torque wrench applications. However, a lower torque range is ideal for smaller tasks, like working on a lawnmower or bicycle. A few brands produce pre-calibrated and precise torque wrenches. Their tools are recognized all over the world thanks to their high quality. These brands can be trusted no matter what tools you want to buy: Accuracy is always an important consideration when it comes to a torque wrench. If the torque wrench is not accurate, it can lead to over or under tightening, both of which can cause serious issues, like breaking or disconnecting.

Ratcheting is a feature that is offered with some torque wrenches, but it isn’t common because torque wrenches should never be used for loosening nuts. This is because when you try to loosen a nut, it may initially be seized, and when the torque wrench applies force, the nut can jolt forward, causing the wrench to require recalibration. A torque wrench is a specialized tightening tool commonly used in the automotive industry. Despite ‘wrench’ being in its name, a torque wrench should never be used to loosen nuts, only for tightening them. Q: How do you use a torque wrench? A convenient, relatively lightweight and capacious storage case can help to keep the torque wrench and its attachments organized and safe from moisture. If the manufacturer sells the tools in a special case, offering space for additional components, this is a great benefit. 3/8 Torque Wrenches FAQ Who makes the best quality torque wrench? The complete steel design of this 1/2-inch drive torque wrench helps protect the internal mechanism from impact damage when the tool is in transport. It has a ±4 percent accuracy rating and an average torque range of 10 to 150 foot-pounds, allowing you to work on lug nuts, spark plugs, and other automotive fasteners as long as you have the correct bits.
