How do you read bolt sizes?
So when you read a bolt that says quarter 20 by 2 that means quarter inch diameter 20 TPI that's threads per inch which would be here.
How do you measure bolt 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.
What does M20 mean?
For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.

What type of bolt has the highest shear strength?
Grade 9 structural bolts, also known as grade 9 hex cap screws, are one the strongest structural bolts that can be used today. While the typical grade 8 bolt has a tensile strength of 150,000 PSI, a grade 9 bolt has a tensile strength of 180,000PSI.
What type of bolt has the best shear strength?
12.9 Bolt Shear Capacity
- 12.9 Bolts. A 12.9 bolt is one of the highest grade of bolts produced. Known for their high tensile strength, they are built with both hex and Torx heads and are available in zinc or chrome finishes. …
- 12.9 Shear Strength. The minimum tensile strength of a 12.9 bolt is 1220 MPa.
What diameter is an m10 bolt?

Is M10 a 10mm bolt?
Metric threads are designated with a capital M plus an indication to their nominal outer diameter and their pitch: This bolt is M10 x 1.5 – which means the outside diameter is 10mm and the threads are 1.5mm apart (the most common thread pitch for M10).
What size drill bit do I need for an M10 bolt?
We use a Fischer type M10 shield anchor. These are specified using a high-grade steel with a corrosion resistant zinc plated finish. The shield requires a 16mm hole to be drilled that is dust and debris free.
What do bolt size numbers mean?
The number 1 or number larger than one, or number one or number larger than one followed by a fraction, is the diameter of the shaft. The number following the hyphen is the number of threads per inch; that is, the number of threads on the shaft itself, per inch of shaft length. Same as for smaller parts.
What are the most common metric bolt sizes?
The most common were the 12mm and 10mm, followed by the 15, 17 and 19mm.
Does M12 mean 12mm?
75 is the measurement code that indicates the thread size and thread pitch of a screw. The first half (M12), is the size measurement (metric) taken across the outside diameter of the thread (which in this case is 12mm).
Does an M12 nut fit an M12 bolt?
M12 nut is inner diameter of nut and M12 washer is M12 clearance hole for inner diameter. So they should all go together nicely. A quick check down B&Q would confirm.
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 m12x 1.75 mean?
M12x1. 75 is the metric way to indicate a thread. M12 means that the OD thread is 12mm, the 1.75 is the step of the thread.
What does m8x1 25 mean?
For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.
Are m10 and 3/8 the same?
That said, they are very close, the 3/8″ bolt is about 0.019″ smaller and the pitch’s are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8 but..
