When discussing engine maintenance, torque ers to the amount of force required to rotate a bolt around a fixed point or axis. In the United States, the Society of Automotive Engineers (SAE) issues standards for bolt and torque specifications; in most other countries, especially European ones, they use metric equivalents.

Metric Dimensions

In metric units, bolts are listed according to three parameters. The first reading is the major thread diameter, listed in millimeters. The second value represents the distance between the threads, in millimeters. The third value represents the bolts length in millimeters. A metric label for a bolt might look like this: M8-1.25x25.

U.S. Dimensions

U.S., or SAE, bolt dimensions are listed according to three parameters. The first value represents the major thread diameter in inches. The second value is the number of threads in the bolt per inch. The third value indicates the bolts length in inches. An SAE label for a bolt might look like this: 5/16-18 1-1/2.

Pound-Feet vs. Netwon Meters

In U.S. units, torque is generally listed in pound-feet (lb.-ft.) or less commonly in pound-inches (lb-in.). In metric units, the same values are listed in Newton-meters (nm). To convert lb-ft. to nm, multiply the value by 1.356. To convert nm to lb-ft., multiply the value by 0.738. To convert lb-in. to nm, multiply the value by 0.113. To convert nm to lb-in., multiply the value by 8.851.

The Chevrolet Motor Company introduced its first vehicle to consumers in 1912. Later merged with General Motors, Chevrolet produces many wheel styles and sizes for its vehicles. Determining the wheel bolt pattern size for your vehicle will enable you to purchase the correct equipment or aftermarket replacements.

Instructions

1

Remove one of your vehicles wheel covers (if equipped) to gain access to the lug studs. Certain original factory wheel covers use faux plastic lug nut covers that secure the hub cap to the rim; you must use an appropriate size lug wrench to loosen the plastic lug nut covers in order to separate the hubcap from the rim. Certain wheel cover styles may require you to pry along the outside parameter, between the rim and hub cap, for proper removal.

2

Count the number of lug bolts that secure the wheel to the vehicle.

3

Measure the distance between the middle of one lug stud to the middle point of the stud directly across when dealing with four-, six- and eight-lug applications. For five-lug vehicles, measure from the outside edge of one stud to the middle point of the farthest stud across.

4

Note the measurement in both metric (millimeters) and American standard (inches). A wheel with five lug studs and a measurement of 4.5 inches translates as a 5-by-4.5-inch or 5-by-114.3-inch bolt pattern when converted to millimeters.

5

Reinstall the wheel cover after obtaining the correct measurements, if necessary.

Regardless of the type of bolt, the tightness that a bolt requires -- its torque -- is essential to using a bolt properly. The torque of a bolt will vary depending upon a number of factors, which can make finding torque specs a little difficult. However, there are many ways to find out what the torque specifications are for a particular bolt.

Torque

When speaking of the tightness of a bolt, one is actually referring to the bolts torque. Torque is the amount of force that is required to rotate an object, like a bolt, around a pivot point. With bolts, the torque is the amount of tightening it requires so that the bolt and whatever the bolt is secured to are not damaged.

Metric Bolts vs. SAE Bolts

There are two major categories of bolts: SAE bolts, which are sized by their diameter, pitch thread and length and are measured in inches; and metric bolts, which are sized by their diameter, distance between threads, and length and are measured in millimeters. SAE or American bolts are used in America; metric bolts are used in most other countries. When looking at a bolt torque specification chart, it is important to check the chart for whether the specs are for SAE or metric bolts, since their torque specs will not be the same.

Bolt Grades

Not all bolts are the same. Bolts are made out of different materials that give them different strengths, uses and capabilities. All bolts have a grade, which indicates the strength of a bolt and what material it is made from. Usually the grade is stamped on the head of the bolt, but metric bolts are sometimes unmarked. Higher grade bolts have higher torque values.

Torque Specs

There are many charts available online that will give a rough estimate of a bolts torque specs based on its size and grade; however, all of these charts are approximations. The torque of a bolt will vary depending upon the manufacturer and other factors, such as whether the bolt is lubricated or dry. There are many instances in which knowing exact bolt specs is essential; for instance, preventing a bolt from breaking or a material from warping. In these cases, contacting the supplier of the bolts for their specs or looking for a chart that is specifically designed for a certain brand of bolt is very important.

Automotive batteries come with either top mount or side mount terminal applications. Top mount batteries require battery cables with clamps that secure over the battery posts. Side mount batteries require cables that have a bolt that threads into the battery. Battery cable bolts can corrode and crack requiring replacement of the bolt. The bolt fits into a groove or channel inside the end of the battery cable. Removing the bolt on a battery cable requires basic brute force and some manipulating of the cable.

Instructions

1

Disconnect the negative battery cable from the battery with a wrench. The negative cable is the black cable and the terminal hole has a - stamp near it. Disconnect the positive battery cable from the battery in the same manner.

2

Grasp the sides of the battery cable where it surrounds the terminal bolt. Bend one of the sides down with your thumb and push the thread end of the bolt to walk the bolt out of the cable end. If necessary, use a pair of pliers to hold one side while you bend the other with your fingers. The hard rubber cable end does bend, but it requires some effort.

3

Hold the battery cable end with your fingers. Insert the threaded end of the new bolt into the battery cable at an angle to insert one of the sides of the bolt ring into the groove in the cable end

4

Twist the bolt with your fingers to thread the ring all the way into the groove, much like you would insert a bicycle rim into a tire. Bend and manipulate the end of the cable as necessary until the ring of the bolt is within the groove and the bolt spins freely with your fingers.

5

Connect the battery cables back into the battery starting with the positive cable first. Tighten the battery bolts to the battery with a wrench.

In short, the bolt pattern for a 2005 Honda Accord is 5x114.3. This number is important to know if you are replacing the wheels or getting custom wheels for the vehicle.

Definition

A bolt pattern is the imaginary circle formed by the bolts that secure a wheel in place. It is measured by how many bolts the wheel has and how many millimeters the diameter of the circle is. You can also measure the diameter in inches.

Number

Five-bolt wheels fit the 2005 Honda Accord. Spaced evenly, they make a star pattern.

Diameter

The bolt pattern diameter on 2005 Honda Accords is 114.3 millimeters, or about 4.5 inches.
