Appendix B: Torque Values - HP 245161-B22 - 10642 42U Rack Shock Pallet Best Practices Manual

Appendix b: torque values

Table 10 provides torque values for specific rack components.
Table 10. Torque values (specific)
Component
All M6 rack hardware
Pallet bracket hold-down bolts
All Phillips-head screws
All M5-M6 slotted-torx head screws
In addition to any specific torque value given in this document, the following tables provide torque
values that can be used to prevent over-torquing a fastener.
The torque values listed in Tables 11 and 12 assume SAE (Society of Automotive Engineers) Grade 2
hardware or ISO (International Standards Organization) 898 property classes less than 8.8 hardware
(for example, 4.6, 4.8, 5.6). Steel hardware for both male and female threads is assumed. For ISO
8.8 or 12.9 and SAE Grade 5 or 8, torque should be determined by the application.
