How are fasteners measured?

Table of Contents

As a general rule, the length of fasteners is measured from the surface of the material, to the end of the fastener. For fasteners where the head usually sits above the surface such as hex bolts and pan head screws, the measurement is from directly under the head to the end of the fastener.

Are m10 and 3/8 the same?

As George says the CG-5 does use the metric 10 x 1.5. 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..

What do screw measurements mean?

A screw for wood is sized by two distinct numbers, first is the gauge of the screw which is the diameter. This means, the larger the number the larger the diameter. Therefore, a number 12 screw is larger than a number 4 screw.

What is bolt gauge?

American Screw Thread Metal Gauge measures the number of threads per inch (from 8 to 44) on screws and bolts. The gauge contains 18 blades.

What is bolt size M10?

Metric clearance and tapping drill hole sizes.

Size	Clearance Hole mm	Tapping Drill (std Pitch)
M10	11	8.5 mm
M12	14	10.25 mm
M16	18	14 mm
M20	22	17.5 mm

What size is that Bolt, Nut, stud, fastener?

The length of the stud bolt should be enough to cover the entire Nut plus 1.5 to 3 threads exposed. Long studs must be avoided as it increases the chance of corrosion and other damage to exposed threads, which would make subsequent removal difficult. ASME B16.5 gives the required size of the stud.

What is the strongest fastener?

Stainless Steel. Stainless steel is an alloy of low carbon steel and chromium for enhanced corrosion characteristics.

Steel. Steel is the most common fastener material.

Silicon Bronze. Silicon bronze,often referred to simply as bronze,is an alloy made mostly of copper and tin with a small amount of silicon.

Brass.

Aluminum.

How to select the correct fastener?

Understand the difference between concrete and cement. Concrete is made up of water,aggregates such as small stones and cement.

Consider the age of the concrete. Do not fasten or drill into concrete that is not older than 28 days.

Find out if the base material is brick or block.

Consider the thickness of the concrete.

What size bolt has a 7 8 head?

What size bolt has a 7 8 head? Also to know is, what size head is on a 7/16 bolt? Likewise, what is M in bolt size? The “M” designation for metric screws indicates the nominal outer diameter of the screw, in millimetres (e.g., an M6 screw has a nominal outer diameter of 6 millimetres).
