We all know that LED light bars are hot selling items and the criminals love them as well. If you already have purchased a LED light bar or similar item or thinking of purchasing one, ensure to invest in these anti-theft nuts and you will gain peace of mind and keep your pride and joy.

These high quality anti-theft Bolts are made from 303 grade stainless steel. The TEE nuts and Tool is Carbon Steel (tool nickel Platted) which provide the protection you are looking for.

I currently stock M8 1.25 14mm
The sizes mentioned above may confuse the non-technical so the key things to consider when selecting the correct nut for your applications and avoid disappointment after purchasing to find out you have the wrong , type, size, diameter etc.
So for the non-technical and to save confusion the simple solution is to take your nut to a hardware store (Bunnings) and use their nut gauge board provided in the nuts and bolt section to source the correct information and your transaction will be trouble free.
How Is a Nut Measured?
Type = Metric, nut size is prefixed with a Mx where x is a numeric number in millimeters ie M10 = 10mm
            Imperial, nut size is labelled UNx where x is the thread type ie: “F” for fine and “C” for coarse
Standard  = M Metric , US standard UN
Pitch / Thread = Thread Count (TPI) stands for Threads Per Inch. This is the number threads per inch measured along the length of a bolt. TPI is used only with American nuts. Ie 20 TPI
Metric nuts are specified with a thread pitch instead of a thread count. The thread pitch is the distance between threads expressed in millimeters. For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm.

Diameter = Outside Diameter (OD) measured in millimeters and is used to select the tool.
Inner Diameter (ID) is for the Blots size also measured in millimeters.

I have included some pictures in the gallery that explain the nut measurements so please review and ensure you select your correct size.
