HiKOKI High-Pressure Screw Nailer 25-41mm Speed Model WF4H3(S)

Product Description

This high-pressure roll collated screw driver is a speed-priority model designed for fast, efficient installation with 25–32 mm screws. It supports screw shaft diameters of 3.5–4.2 mm, screw lengths of 25–41 mm, and holds 100 screws per roll. Suitable for a wide range of applications from wood substrates to steel framing, it delivers reliable performance for professional job sites.

Built for cleaner and smoother fastening, it features reduced cam-out for improved finish quality and longer bit life.

It also supports DTSN (JIS standard screws) without requiring bit changes, using a single dedicated WF4H3 bit for all compatible screw types.
