Our product rangefocuses on the needs and demands of the industry sectorDr. Uwe Hasselmannfor manufacturing, which includes assembly material forHead of Technical Departmentcontructions, machines and vehicles as well as equipmentfor their maintenance.Most U.S. companies that utilise inch fasteners in theirassembly process, export those products or also have pro-INCH FASTENERS2

American ThreadsIn this brochure we want to introduce two types of threads to you. These are the American Standard-Coarse ThreadUNC and the Standard-Fine Pitch Thread UNF. Both of these threads are part of the new standard assortment of WurthIndustrie Service.The difference between the metric and the american thread is that the metric range shows the lead of the thread (e.g.M8 x 1,25 mm) and the american range shows the threads per one inch (25,4 mm).UNCUnified National Coarse Thread SeriesAmerican Standard-Coarse Threade.g. Description3/4“–Thread diameter10 UNCx1“lengththreads per 1 inchUNFUnified National Fine Thread SeriesAmerican Standard-Fine Pitch Threade.g. Description3/4“Thread diameter–16 UNFx1“threads per 1 inchlengthBesides the threads there are other differences between inch and metric items. Inch fasteners are not just used in the U.S.but for instance also in Great Britain. The difference between an American thread and an English thread is the threadangle as shown below:Difference between thread angle UNC (America) and BSW (Great Britain)UNC American Standard-Coarse Thread, 60º thread angleBSW British Standard-Coarse Thread, 55º thread angle3Inch FASTENERS
