What is Nm on torque specs?
In the bike industry and elsewhere, the common unit used to measure torque is the Newton meter (abbreviated Nm). One Newton meter is a force of one Newton on a one meter long lever.
What does Nm mean on a bolt?
Torquing produces this load through rotational force on a nut or bolt head. This torque is usually measured in foot-pounds (ft-lbs.) or Newton-meters (Nm).
What is torque Nm in bike?
Torque is rotational force. It’s calculated by Force x Radius. Torque of 100 Nm (Newton-meter) means that at a 1 meter radius a force of 100 Newton can be applied, which is the same as being able to apply a force of 73.7 pounds at a radius of 1 foot. Nm (Newton-meter) is the metric unit for Torque.
What is the proper torque for lug nuts?
Under- or over-tightening wheel-attaching hardware can be damaging and dangerous.
| Hardware Bolt or Stud Size | Typical Torque Range in Ft/Lbs | Minimum Number of Turns of Hardware Engagement |
|---|---|---|
| 14 x 1.25 mm | 85 – 90 | 9 |
| 7/16 in. | 70 – 80 | 9 |
| 1/2 in. | 75 – 85 | 8 |
| 9/16 in. | 135 – 145 | 8 |
Does anti-seize increase torque?
The torque applied to a fastener with an antiseize compound pre- applied to the threads will ensure uniformity through out the process but will increase the Clamp Load compared to an unlubricated bolt.
Should you copper grease wheel bolts?
Yes, copper grease should be put on the hub spigot, this is where they normally stick. Ideally you shouldn’t put any grease on the threads or on the contact face with the hub – as number cruncher says this is basically a friction coupling to your wheel. Torque should go through this and not through the wheel bolts.
Do mechanics actually use torque wrenches?
A torque wrench is a tool used to control and apply a specific torque to a fastener such as a bolt or a nut. It is a fundamental element in general mechanics, tire changing operations and industrial maintenance and repair industries, to ensure customers’ safety.
What is a good torque for a bike?
Normal horsepower ranges for full-size motorcycles are probably between 15 and 200 horsepower. (Yes, exceptions exist, but most will fall within that range.) Torque specs will usually ring in at 10 to 175 foot-pounds. In general, the bigger the torque number is, the stronger a bike will feel low in the rev range.
