Server Chassis: Review Hardware, Bends & Assembly Interfaces

Use a common datum scheme

Identify the surfaces and holes that locate the rack, rails, boards and removable covers. Show the dimensions that control these relationships and review accumulated variation across mating parts.

Confirm the hardware before hole release

Specify the fastener manufacturer or approved equivalent, part number and installation direction. Check sheet thickness, hardness, hole requirements and edge distances against the selected fastener's documentation; there is no single universal hole size for all self-clinching hardware.

Check access after forming and finishing

Review tooling access around bends, hardware insertion access, cover removal and cable clearance. Agree the process sequence with the fabricator and check coated mating surfaces on the sample assembly. Do not infer bend limits or installation forces from an animation.
