For the complete set, Northern Tool lists approximately:
- Overall/Package Dimensions: 10.5 × 1.25 × 5.5 in
- Listed Weight: 0.65 lb / 10.4 oz Northern Tool
I would treat those as retailer-listed set/package measurements rather than manufacturer-confirmed individual screwdriver dimensions.
Performance
This is a manual screwdriver set, so there is no applicable power or torque rating.
The specialized clutch-head profiles are designed to properly engage older Clutch G / Figure 8 fasteners and can also engage Clutch A fasteners. CTA Manufacturing

- Older GM/Chevrolet cars and trucks
- Headlight buckets
