High-Density 12 Piece Phillips and Slotted Screwdriver Set with Hex Bolsters and Tri-Lobe Handles
The Crescent CSD12 12-Piece Phillips and Slotted Screwdriver Set delivers a professional industrial manual fastening solution engineered to rotate, loosen, and torque structural fasteners across production and maintenance job sites. Featuring high-strength chrome-plated alloy steel blades, this comprehensive hand tool array utilizes precision-machined tips to ensure tight tolerance fitting inside screw heads, effectively eliminating slipping and destructive cam-out. The specialized dual-material tri-lobe handles maximize manual twisting torque while resisting shop chemicals, and select larger sizes integrate specialized hex bolsters that receive open-end wrenches to multiply turning leverage against frozen or rust-locked screws.
Best Used For:
- Commercial HVAC Maintenance: Accessing and removing panel covers, fan shrouds, and electrical control housing screws efficiently.
- Automotive Mechanical Repair: Slicing through engine grime to drive or extract standard interior and engine compartment fasteners.
- Industrial Facility Assembly: Securing hardware components, terminal blocks, and structural mounts during high-volume field wiring setups.
Key Performance & Safety Features
- Ergonomic Tri-Lobe Grips: Co-molded handle geometry conforms with hand contact contours to transfer peak torque with minimal manual force.
- Leverage Hex Bolsters: Hardened wrench flats integrated near the handle base permit open-end wrench adaptation to bust seized fasteners loose.
- Precision-Machined Tips: Factory-milled driver bits achieve a flush mechanical seating within slot walls to stop point stripping.
- Rapid Size Identification: Handle butt ends are permanently stamped with drive style indicators paired with laser-etched blade sizing labels.
- Solvent Resistant Core: High-density dual-material handle polymers maintain structural bonding when contacting automotive oils and chemical shop fluids.

Pro-Tip: When breaking loose stubborn, over-torqued panel screws, press your palm down hard on the handle butt before turning the wrench on the hex bolster. Direct axial pressure seats the driver tip perfectly inside the fastener slot, preventing the bit from climbing out and stripping the slot profile.
