Please read your question again. ■

Maybe you wanted to know what is the difference between N/mm and KN/m. It's the same ! K is an abbreviation for Kilo and is the international symbol for 1,000.

But if you want to buy some belt fasteners take care about following things:

1) The manufacturers of fasteners have developed fasteners in order to reach more than 50 % of the strength of the belt. Mostly not more ! This strength is only a static strength measured under labor conditions on a new and perfect belt. If the belt carcass is poor quality (old belt, low cost belt) it's better to calculate with the real working tension and to aks the manufacturer.

2) You have forgot the third manufacturer of Fastener. It's Minet Lacing Technology, who have developed some very new and innovating fasteners in order to permit the installation without the need of a specific tooling (the tooling cost is 10 to 30 time the cost of one fastener!) and without the need of high skilled people.

The Super-Screw fastener i.e. is also compatible with most of the scrapers (also with hard metal blade) and is leak proof like a hot splice. So if you want to take something other than a hot splice I recommand to have a look on www.mlt-usa.com ■

threecolors,

The choice of mechanical fasteners depends on the type of belt and process requirements.

Top general purpose mechanical fasteners for heavy-duty belting include Flexco and Minet. The Mato fastener is a special purpose fastener that works well with straight warp carcass belts.

Note that mechanical fastener strength percentage ratings normally refer to the belt rating, not to the ultimate belt strength that includes a large safety factor. Belt and fasteners strengths may be expressed in terms of kN/m, N/mm, or PIW (Pounds per inch of width). The strength expressions of the metric and Imperial systems can be easily converted from one to another using basic conversion factors.

It is usually a good idea to check with your belt manufacturer for input on fastener choices.

Hope thius helps. ■
