17、 EN 3294:20084 1 Scope This standard specifies the dimensions of uncoated T-head bolts, close tolerance, with MJ-thread, thread length for increased height nuts, in heat resistant nickel base alloy NI-P101HT for aerospace applications. Maximum test temperature of the parts is 730 C. These bolts are
18、to be used in aerospace fastening systems mainly stressed in shearing force. 2 Normative references The following referenced documents are indispensable for the application of this document.
