Based on my research it looks like you have a hub for a 3,500 lb axle, though we do not have any exact reference for an H-1377 hub to go off of.

You only need to know whether your hub uses screw-in or drive-in studs as well as the length of stud you need. This is going to require you to remove one of your wheel studs and if they are drive-in they will have a head on them like the 1/2" x 2-1/2" Wheel Stud # 165995. A screw-in like the 1/2" x 2" Wheel Stud # 25-53 will be completely threaded.

I have added a link below to our entire selection of wheel studs for you once you determine the type and size for your hub.
