What is my screw size?

To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.

How do you read screw sizes?

Look at the first number to find the screw’s diameter.

It corresponds to the width of the threads on the screw’s shaft. In the metric system, the diameter is always measured in millimeters. For instance, on a M12 x 1.75 x 85 callout, M12 is the diameter. It means the external threads are 12 mm (0.47 in) wide.

What are M3 and M4 screws?

As a rule of thumb, the diameter of the clearance hole is more than the diameter of the screw. The M3 screw’s clearance hole is either 3.5 or 3.2mm. The M4 screw has a clearance hole of at least 4.2mm.

What do screw size numbers mean?

How are metric screws sized?

Metric nuts and bolts are commonly referenced using ‘M’ sizes, for example: M3, M8, M12. But the size of a metric fastener is more accurately specified using diameter, pitch and length dimensions, in millimeters. For nuts the size dimensions used are simply diameter and pitch.

What size is M6 in mm?

6 mm

M6 refers to a metric 6 mm screw. The outside diameter of the threads is 6 mm. The standard metric rack screw is actually an M6 x 0.1 mm. The number 0.1 mm refers to 0.1 threads per millimeter.

Is M6 the same as #6?

M6 threads are 6mm metric screws. The standard metric rack screw is called M6 x 1. The ‘M’ means it’s metric. The ‘6’ is the outside diameter measured in millimeters, and the ‘1’ is the distance between adjacent threads, also in millimeters.

How can you tell if a bolt is metric or standard?

For both metric and standard bolts, the head size is the distance across the flats. For standard bolts, the head size is measured in inches or fractions of an inch. For metric bolts, head size is measured in millimeters. However, metric bolt head size is measured in millimeters.

What does M mean for bolts?

metric size

Taking a closer look at this description, let’s explore its meaning: M = This designates the fastener is a metric size. 10 = The nominal diameter in millimeters. 1.0 = The thread pitch, or distance between threads, in millimeters. 20 = The fastener’s length, in millimeters.

Are standard and metric threads the same?

Metric thread pitch measurements are read differently than standard ones. While for standard thread pitch measurements the lower number is coarse thread and the higher number refers to fine thread, in metric this is opposite. M10-1.50 is a coarse thread denotation while M10-1.25 is a fine pitch.

What is difference between mm and inch bolt?

Metric thread callouts are fundamentally different because the thread pitch (distance between each thread, in mm) is specified instead of threads per inch or per mm. For example, an M10x1. 5 (coarse) thread has a 1.5mm pitch, while an M10x1. 25 (fine) thread has a 1.25mm pitch.
