What is this product
The Klein Tools 32931 is a compact 3-in-1 impact flip socket that combines two common SAE nut driver sizes, 1/4 and 5/16, plus a 1/4-inch bit holding feature in one tool. Flip it to switch sizes, or use the bit holder for quick fastening changes. It is impact rated for use with impact drivers and compatible 1/4-inch quick-connect handles.
TL;DR: Who is this for
- Electricians and HVAC installers driving sheet metal screws, self-tappers, and common hex-head fasteners
- Low-voltage and security installers mounting brackets, racks, and enclosures with 1/4 and 5/16 hardware
- Maintenance teams doing repetitive fastening where swapping between nut driver sizes wastes time
Institutional Fit
- Strong for service fleets standardizing on a compact impact-rated nut driver solution
- Reduces tool count in technician kits while covering two high-frequency sizes plus 1/4-inch bits
- Rare earth magnet helps reduce dropped fasteners in panels, ladders, and overhead work

Regulatory Compliance
- Not a regulated electrical component. Use proper PPE and follow site fastening and tool safety procedures.
Durability and Lifecycle
- Steel alloy construction and impact-rated design supports repeated impact driver use
- Manganese phosphate finish helps resist wear and corrosion in jobsite conditions
- 6-point socket geometry helps reduce rounding compared to 12-point designs in high-torque situations
Procurement notes
- If your crews commonly use 1/4 and 5/16 hex-head fasteners, this replaces carrying two separate nut drivers
- Use the bit holding feature to switch from hex-head driving to bit driving without changing tools
- Rare earth magnet helps with screw retention, especially for overhead installs and ladder work
- Confirm your driver interface: designed for 1/4-inch drive systems and quick-connect handles (handles not included)
