The first two digits define the mounting thread: -01 = 1\/4-28 UNF integral stud, -02 = M8 x 1 integral stud. The last two digits define certifications: -00 = no approvals, -05 = multiple agency approvals (CSA, ATEX, IECEx). Thus, 330400-01-00 means 1\/4-28 UNF stud with no agency approvals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between 330400-01-00 and 330400-02-00?\u003c\/strong\u003e\u003cbr\u003eA: 330400-01-00 has a 1\/4-28 UNF integral stud; 330400-02-00 has an M8 x 1 integral stud.
