Notes:
1. Definitions:
DRY: Cadmium plate, zinc plate, and oiled fasteners.
LUBRICATED: Molysulfide paste, carnaba wax, molysulfide grease and
copper-based anti-seize coated fasteners.
PTFE: 2% minimum PTFE coated fasteners.
2. All torque values foot-pounds unless noted.
3. SAE grade 5 equivalent to ASTM A325 Type 2 and ASTM A449.
4. SAE grade 8 equivalent to ASTM A354 Grade BD, ASTM A490 Type 1.
5. If mixing fasteners use lowest torque value.
6. Torque values 75 to 85% of fastener proof load ref.
