: For the overall length, take into account the<br />
length of the standard design for HFE. This is<br />
also valid for the dimensions d2, sm, a and t on<br />

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