Bsc Preferred 167512 Ratcheting Precision Screwdriver Set

Product Description

The BSC PREFERRED 167512 is a 26-piece ratcheting precision screwdriver set built for detailed assembly, electronics work, and tight-tolerance fastening tasks. The set includes a ratcheting screwdriver handle, a 4.5-inch extension bar, and 24 chrome-vanadium (CR-V) bits spanning five driver types: hex, star (Torx-style), tri-wing, Phillips, and slotted. CR-V construction provides hardness and corrosion resistance suited for repeated professional use. The compact bit assortment covers a wide range of small-fastener sizes, making this set practical for technicians who work on equipment panels, controls, and precision assemblies.

This set is appropriate for HVAC controls technicians, electricians, appliance service technicians, and instrumentation professionals who regularly encounter small-head fasteners on circuit boards, control panels, and access covers. The tri-wing and star bits extend usefulness to consumer electronics and proprietary fastener systems common in modern equipment enclosures. The ratcheting handle reduces hand fatigue during repetitive fastening in confined spaces.

Installation Notes

Always de-energize and lock out electrical equipment before accessing internal fasteners on control boards or panels, following NFPA 70E safe work practices. Select the correct bit profile and size before driving to avoid fastener head damage. The extension bar should be seated fully before applying torque. Store bits in the provided case to prevent loss and corrosion.
