What are the sizes of wrenches in order?

Wrench Sizes In Order Standard sizing in America are as follows: 5/8, 19/32, 9/16, 1/2, 7/16, 3/8, 11/32, 5/16, 9/32, 1/4, 7/32, 3/16, 5/32, and 1/8. These are set out from the smallest wrench to the largest, and you will be able to buy these wrenches individually or in wretch sets.

What are the SAE wrench sizes?

The most commonly used and sold SAE sizes for wrenches and sockets are:

  • 5/16″
  • 3/8″
  • 7/16″
  • 1/2″
  • 9/16″
  • 5/8″
  • 11/16″
  • 3/4″

What is a 3/4 wrench in metric?

3/4″ 29mm. 1-1/8″ 32mm.

What does SAE stand for in wrenches?

Society of Automotive Engineers
SAE or Standard: A standard or SAE (Society of Automotive Engineers) wrench is measured in fractions of inches.

What is 17 mm SAE?

SAE to Metric Conversion Chart

SAE Metric Inch
21/32″ 0.656
17mm 0.669
11/16″ 0.688
18mm 0.709

How do you read a wrench size?

Usually, standard wrenches are measured by their spanner dimension. For example, a 2-inch standard wrench will measure 2 inches from parallel flat sides on the hexagonal wrench head.

Do American cars use SAE or metric?

American cars are assembled with nuts and bolts that use standard measurements while foreign cars almost exclusively use metric measurements.

Is SAE and imperial the same?

How to Convert Between SAE and Imperial Socket Sizes? There are two different methods for measuring the hex sizes of sockets. The SAE (Society of Automotive Engineers) system uses inches, and the imperial or metric system uses millimeters.

Is a 19mm socket the same as 3 4?

19mm = 3/4 inch. 20mm = 25/32 inch. 21mm = just over 13/16 inch. 22mm = almost 7/8 inch.

How do you convert SAE to metric?

How to Convert SAE to Metric

  1. Step One: Convert the Fraction to Decimal. The first step is to convert the inch fraction to a decimal.
  2. Step Two: Convert to Millimeters. The next step is to multiply the inch decimal by 25.4 to convert it to millimeters.

Whats better metric or SAE?

Metric is the preferred fastener measurement throughout the world. More exact than fractions of an inch, metric measurements–based on millimeters–are a precise representation of the diameter of the head of the fastener.

Is imperial and SAE the same?

Is 7mm and 9/32 the same?

7mm = almost 9/32 inch (= a bit over 1/4 inch) 8mm = 5/16 inch. 9mm = almost 3/8 inch. 10mm = just over 3/8 inch.

Why is there no 16mm wrench?

1911, is there a reason they don’t use any 16MM nuts or bolts? 16mm and 18mm nuts / bolts are most commonly found on American vehicles that converted to metric hardware, and not import vehicles designed with metric hardware. So, you don’t find them in most basic wrench / socket sets.

What do wrench numbers mean?

These multiple standards meant that some wrench openings might be marked with three size indications. For example, a number 23 wrench would be marked “3/16 U.S.S.” for the small opening, and “1/4 U.S.S.”, “5/16 Hex Cap”, and “5/16 S.A.E.” on the larger end. Also, the U.S.S. size was sometimes marked as “NUT”.

What size is a 3/8 wrench?

STANDARD / METRIC WRENCH CONVERSION CHART

BOLT DIAMETER STANDARD METRIC
3/8″ 9/16″ 14mm
7/16″ 5/8″ 16mm
1/2″ 3/4″ 19mm
9/16″ 13/16″ 21mm

Is Chevy a metric or SAE?

Does GM use all metric or a combination of SAE and metric? With only a few exceptions, all vehicles now use the metric system for hardware. The last time I checked the spark plugs and O2 Sensors were SAE. That may have changed on newer models.

Who still uses SAE?

Only three countries – the U.S., Liberia and Myanmar – still (mostly or officially) stick to the imperial system, which uses distances, weight, height or area measurements that can ultimately be traced back to body parts or everyday items.
