## Summary description

Wera PH1 3851/1 TS screwdriver bit made of stainless steel with SiS coating. Designed for Phillips (PH) screw heads, 6.3 mm (1/4") hex shank, supplied as a single piece. Compatible with bit holders and drivers that accept 6.3 mm bits. Provides corrosion resistance and precise fit for assembly, repair and maintenance tasks.

## Long description

Wera PH1 3851/1 TS is a single-piece screwdriver bit made of stainless steel with a SiS (silicon nitride) coating. It is shaped for Phillips (PH1) screw heads and finished with a 6.3 mm (1/4") hex shank for use in bit holders and drivers that accept standard 6.3 mm bits. The stainless steel construction offers enhanced corrosion resistance while the SiS coating improves wear resistance and reduces cam‑out during assembly, repair and maintenance operations.
Advantages
The stainless steel body provides durability and resistance to rust in humid or corrosive environments. The SiS coating increases surface hardness, improves torque transfer to Phillips screw heads, and extends service life compared with uncoated bits. The 6.3 mm hex shank is compatible with a wide range of hand drivers, quick‑change bit holders and power tool adaptors, enabling fast bit changes and stable fit. Supplied as a single, precisely machined unit, the bit ensures accurate seating in compatible fasteners for consistent drive performance.
Suitable for
 Assembly and disassembly of electronics and household appliances with PH1 fasteners
 Maintenance and repair tasks in automotive interiors and trim
 Work in environments where corrosion resistance is required
 Use with 1/4" (6.3 mm) bit holders, ratchets and quick‑change chucks
Key specifications
 Tip type: Phillips PH1
 Material: stainless steel with SiS coating
 Shank size: 6.3 mm (1/4") hex
 Form: single piece bit
 Typical applications: manual driving and light to medium torque powered drivers
How to use
Insert the 6.3 mm hex shank into a compatible bit holder, ratchet or power driver and ensure it seats securely. Align the PH1 tip with the screw head and apply steady axial pressure while turning to avoid slipping. For power tools, set the torque or clutch to an appropriate level for the fastener and material to prevent over‑tightening. After use, wipe the bit clean and store it in a bit organizer to preserve the SiS coating and prevent contamination.
Usage recommendations
Use the bit with the correct PH1 screw size and avoid applying excessive sideways force. For repetitive powered driving, choose appropriate torque settings and inspect the tip for wear; replace the bit when the tip shows rounding to maintain proper engagement and reduce the risk of fastener damage.
