More than you ever wanted to know about measuring screws

How To Measure A Screw

 
 
 
 
      
 

Notes on sizing: Average dimensions are now given for each screw. These are useful if you are trying to find an exact replacement screw. However, in most cases you can substitute a slightly longer or shorter screw.

 

For instance the difference in the length of a screw that is 2.20 and one that is 2.40 is only the thickness of a business card. A dollar bill is 0.1mm thick and a blonde hair is .04mm

 

Sizing for oem laptop screws is a bit confusing. When the screws are produced there are +/- allowances on length. What this means is that a screw considered to be 8 mm long may actually measure 7.6mm or 8.0mm. It may be measured from under the head or the overall length.

 

The actual diameter of an M3 screw is usually about 2.9mm, an M2.5 screw is 2.4mm and an M2 is 1.9mm.

 

We give both the overall length and the thread length. The clickable size given in the menu on the left is the thread length in the case of pan head and oem wafer head but the overall length for the flat head screws. Some laptop manufacturers (ie HP & Compaq) measure overall length but some measure from underneath the head like you would a regular pan head. So be aware of this if you are using sizes given in a service manual.

 

If you are using a service manual to get a size please be aware that mistakes have been found in some manuals. M2.5 reported as M2 or M3 reported as M2.5

 

The name of our OEM screws is the measurement taken from underneath the head. The average overall length is also given as well as the thickness of the head. Our other screws are listed under their industry standard size.

 

If you are ordering from sizes given in an HP or Compaq manual remember that they measure the overall length of the screw. This means that if they say the screw is an M2.5x9 the rest of the world will call it an M2.5x8 so you will need to look in the listings for the next smaller size.

 

If you are having difficulty locating your exact size don't forget to look at the larger or smaller sizes as it may not be listed under the heading where you are searching.

 

For instance if you are measuring an M2x5 pan head screw the overall length will be 6.60mm but it will be listed under the M2x5 because a pan head is measured from underneath the head where as a standard flat head screw takes its size from the measurement taken from top to bottom.

 

Please don't hesitate to write if you have any problems using our new layout.

 

Yes, we know that it is confusing. We are trying to remedy that as much as possible. If you have any recommendations about how we can improve your buying experience please don't hesitate to let us know.

USING THE MENU

M2 = diameter  

3mm = thread length    

(3.00 to 4.60) = average overall screw length in that category including the head.

You will note the overlapping sizes, this is due to the variance in head thicknesses.
