What is the specification for the bottom plate screws of the Rossmont 4?
Thread Content
It’s the 4 screws at the bottom – what are their specifications?
7/16UNFX1.75; the thread might also be M10*1.5
Actually, if you check the selection manual corresponding to the specific model on the transmitter, all of that information is there
How can there be two types? After 7/16UNF, it shouldn’t be a pitch of 1.75 according to the national standard either
1.75 is the bolt length: 1.75×25.4=44
I’ll give you the standard answer: those threads are metric, M10 or M12; I’m not quite sure. You can find out by using a caliper – the pitch of the threads is 1.25. That is: the screw model is M12*1.25
This screw is used to connect the transmitter body to the three-valve assembly; it is typically used in conjunction with such assemblies and usually has an internal hex shape. As for the material, high-quality 316 steel is recommended for areas prone to corrosion. The bottom part of the three-valve assembly should be protected with explosion-proof putty, and our protection method proves to be quite effective.
Yes, it’s 1-3/4 in length. Are there any details on the coarse and fine threads as well? There are two types: 7/16UNF-14 and 7/16UNF-20
-14 is UNC, -20 is UNF
