Bits for Phillips Screws
The Wera 851/1 TH Phillips (PH2) bit (05056610001) is a replaceable bit designed for tightening Phillips (PH2) screws. The bit has a blade length of 25 mm and a 1/4" hexagon drive in accordance with Wera's connecting series 1. The product is designed as a so-called TH bit with an integrated torsion zone, which is designed to absorb peak torques and protect the bit from harmful twisting.Function and Design
The Wera 851/1 TH Phillips (PH2) bit (05056610001) combines an extra-hard bit material with a torsion zone. The torsion zone reduces the harmful effects of sudden torque spikes by dissipating energy in this zone, which, according to the manufacturer, reduces premature wear and extends the bit's lifespan. The bit has a standard 1/4" hexagon drive, making it compatible with common bit holders and connections in Wera's connecting series 1.
Typical Applications
- For tightening and loosening Phillips screws in size PH2.
- Used with 1/4" bit holders and adapters where an extra-hard bit and torsion absorption are desired.
- The manufacturer states that screws can be installed without damaging the surface when used correctly.
