The BITPZ2100 Tub is a bulk supply of Pozidriv driver bits designed for use with power and impact drivers. Its primary use is rapid, repeatable screw driving where Pozidriv fasteners are specified — common in construction, joinery, M&E installations and general assembly work — providing a consistent fit to minimise cam‑out and wear when used with compatible power tool chucks or quick‑change bit holders.

Each bit in the tub is manufactured from S2 shock‑resistant tool steel and is heat treated to deliver the torsional strength and toughness required for impact use. The tips are formed to the Pozidriv profile (PZ) and finished with a black phosphate coating to improve corrosion resistance and lubricant retention. The bits feature a 1/4" (6.35 mm) hex shank compliant with DIN 3126 (C 6.3) for secure retention in quick‑change chucks and magnetic bit holders. Thread type is not applicable for this type of driver accessory.

Typical applications include fixing plasterboard and drylining, fitting furniture and cabinetry, mechanical and electrical installations, timber frame assembly and general site maintenance. Trades that rely on repeatable screwdriving — carpenters, electricians, installers and service engineers — will find the tub format convenient for workshops and van stock where frequent access to PZ bits is required.

Key benefits of the BITPZ2100 Tub are the combination of impact‑rated S2 steel for strength and shock resistance, the Pozidriv tip profile for reliable engagement with PZ screws (reducing cam‑out), and the 1/4" hex shank compatibility that works with the majority of modern impact drivers and quick‑change chucks. The black phosphate finish offers improved corrosion protection compared with untreated bits and helps extend usable life under normal trade conditions.

Duchy Fasteners stocks these bits in practical tub packs alongside single‑size and mixed assortments covering common PZ sizes (PZ0–PZ3) and a range of lengths suitable for site, workshop and industrial use. Please contact us for availability of specific sizes and pack quantities.
