Screwdrivers

The Wiha Torx T2 Precision 278 (model 881SC7802.T2) is a high-precision screwdriver designed for use with very small Torx (T2) screws in electronics, instrumentation, and sensitive assemblies. It belongs to Wiha’s 278 Precision / ESD Safe / PicoFinish family, offering excellent tip accuracy, ergonomic handling, and optional ESD-safe features for safeguarding components sensitive to static. It balances control, torque feedback, and compactness, making it suited for tasks where delicate fasteners demand precision over brute force.

Features & Benefits:
*Torx T2 tip geometry: Ensures a tight, precise fit in Torx T2 screw sockets, minimizing cam-out and reducing damage to both screw and driver.
*Exact-fit precision machined tip: Maintains tight manufacturing tolerances to reduce slippage and preserve engagement under repeated use.
*Through-hardened blade made from high alloy steel: Resists bending or deformation under torque and ensures long tool life.
*Rotating cap: Allows smooth fingertip rotation for fine adjustments and controlled torque application.
*Ergonomic handle (often ESD / dissipative variant in 278 line): Offers comfortable grip, good tactile feedback, and (in ESD versions) controlled discharge of static to protect electronic components.
*Compact overall dimensions: Blade and handle lengths optimized for confined spaces, reducing interference in tight assemblies.
*Durable finish / tip treatment: Protects against wear and corrosion to extend life of tip integrity.
*Professional grade construction: Built to perform reliably under frequent use in workshop and service environments.
