OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules.

|MEMORANDUM FOR:||BARRY J. WHITE
|THROUGH:||DONALD E. MACKENZIE
Acting Director, [Directorate of Cooperative and State Programs]
|SUBJECT:||Request for Interpretation Clarification of Standard 1926.751(c) Pertaining to "Double Connection"|
The "Double Connection" is frequently used in structural steel assembly to bolt perlins or beams to the web of girders. The procedure you described is acceptable for the erection of beams or girders at columns, provided the bolts are wrench-tight after the initial connection at one end of the beams or girder and finger tight at the other end.
[Correction 6/20/2005. See OSHA Directive CPL 02-01-034 "Inspection policy and procedures for OSHA's steel erection standards for construction" published on 3/22/2002 for the current policy on OSHA's steel erection standards (1926 Subpart R) for construction.]
