Alternate dog point – MAThread ® upon request
HFHD studs can also be manufactured with a
MAThread ® dog point upon request.
Anti cross-threading design allows the threads to
self-align and the use of shorter lengths.
The thread of the assembly nut already grips when it
comes into contact with the MAThread ® . Saves weight.
