Torque Reference For SAE Grade 2 Fasteners
Torque depends on size, thread and lubrication - the figures below are plain-finish starting points for common UNC sizes.
Match Grade To Chart
Confirm the fastener is unmarked Grade 2 before applying these dry-torque values.
Check Bolt Length
1/4″-3/4″ bolts longer than 6″ drop to Grade 1 torque figures.
Account For Plating
Zinc or galvanized finish changes friction, so adjust the plain-torque number.
Re-Torque Critical Joints
Re-check fasteners exposed to vibration or repeated thermal cycling.
