Product Category: Bits
Product Overview
The Wera 851/1 TZ Phillips bit PH2 (05056510001) is a single bit for Phillips screws with a blade length of 25 mm. The bit features a torsion zone designed to absorb peak torque loads. The drive interface is 1/4" hexagon (Wera connecting series 1) and is suitable for holders according to DIN ISO 1173-D 6.3.
Function and Features
The bit functions as a replacement or spare bit in screwdriving applications where Phillips PH2 is required. The integrated torsion zone reduces stress on the tip during momentary torque peaks, which, according to the manufacturer, reduces premature wear and extends the bit's lifespan. The bit is described as "tough for hard materials" in the manufacturer's product text.
