MAXTEC 25mm Impact Screwdriver Bits - PZ2 - Pack of 25

MAXTEC 25mm Impact Screwdriver Bits

The MAXTEC 25mm Impact Screwdriver Bits are PZ2 Pozidrive bits manufactured specifically for use with impact drivers. Supplied in a pack of 25 in a tub container, they are suited to production screwdriving tasks where bits are consumed regularly and having spares to hand is essential for uninterrupted work. The 25mm length is the standard size for use in magnetic bit holders and direct ¼" hex chucks, covering the vast majority of general screwdriving applications on site and in trade use. PZ2 is the most widely used drive type for wood screws on UK construction sites, making this pack a daily-use consumable for carpenters, joiners, and general contractors.

Why Choose the MAXTEC 25mm Impact Screwdriver Bits?

• Impact rated: These bits are designed specifically for impact driver use. Standard non-impact bits used in an impact driver wear faster and are more prone to snapping under the high-torque burst forces an impact driver generates. Impact-rated bits are manufactured to handle these forces consistently across a greater number of driving cycles.

• PZ2 Pozidrive drive: PZ2 is the most common drive type for wood screws in UK construction, covering the majority of general-purpose wood screws used in timber framing, first and second fix carpentry, decking, and general site assembly.

• 25mm standard length: The standard length for use in magnetic bit holders and ¼" hex chucks. Compatible with the CMT Magnetic Bit Holder (BMBHSTD) and Magnetic Quick-Release Bit Holder (BMBHQS).

• Pack of 25: Impact bits are a consumable. Having 25 in hand means the job is not interrupted by a worn or broken bit. The tub container keeps the pack organised and protects unused bits from damage on site.

• MAXTEC brand: Part of the CMT Group MAXTEC range of power tool accessories, manufactured for trade and construction use.

Who Is This For?

These bits are for carpenters, joiners, drywall fixers, decking and fencing installers, general contractors, and site operatives who use an impact driver as their primary screwdriving tool and work regularly with PZ2 Pozidrive head screws. The pack of 25 is suited to operatives who go through bits at volume and need a reliable supply to hand throughout the working day.

Typical Applications

• Driving PZ2 Pozidrive wood screws in timber framing, first and second fix carpentry

• Decking, fencing, and general outdoor timber fixing with PZ2 screws

• Drywall and plasterboard fixing with PZ2 screws

• General site assembly and fixing work using PZ2 Pozidrive fasteners

• High-volume screwdriving where bit replacement during the shift is routine

• Any application where an impact driver and PZ2 Pozidrive screws are used together

How to Use

1. Insert the ¼" hex shank of the bit into the magnetic bit holder or directly into the ¼" hex chuck of the impact driver.

2. Ensure the bit is fully seated and retained before operating the tool.

3. Position the bit tip in the PZ2 Pozidrive screw head recess and apply light forward pressure to maintain contact during driving.

4. Drive to the required depth. Reduce speed as the screw approaches full depth to avoid cam-out or overdriving.

5. To change a bit, pull it free from the magnetic holder or release it using the quick-release collar if using the BMBHQS holder.

6. Inspect the bit tip before reuse. A worn or damaged tip should be replaced immediately.

Safety

• Always ensure the impact driver is switched off before fitting or changing bits.

• Do not use a worn or damaged bit. A worn tip will cam out of the screw head under impact force, potentially damaging the fastener or the work surface.

• Wear appropriate eye protection during all impact driving operations.

• Do not use these bits in applications requiring a different drive type. Using a PZ2 bit in a Phillips screw or vice versa will damage the bit and the fastener head.

Maintenance

• Store unused bits in the supplied tub container to protect the tips from damage.

• Inspect bit tips regularly during use. Replace bits showing signs of wear, rounding, or tip damage.

• Keep the tub container closed when not in use to prevent bits from being contaminated with swarf or debris.

• Store in a dry location to prevent corrosion on the bit shanks.

Frequently Asked Questions

Q: What does PZ2 mean?

 A: PZ2 refers to Pozidrive drive size number 2. Pozidrive is the most widely used screw drive type for wood screws in UK construction. It is designed to resist cam-out better than Phillips under high torque, making it the preferred drive type for timber and general construction fixing. PZ1 is smaller and PZ3 is larger.

Q: What is the difference between PZ2 and PH2?

 A: PZ2 is Pozidrive size 2 and PH2 is Phillips size 2. They look similar but are not interchangeable. Pozidrive screws have additional ribs in the recess that a PZ bit engages with, giving better torque transfer and resistance to cam-out. Using a PH2 bit in a PZ2 screw or vice versa will damage the bit tip and the screw head. Always match the bit type to the screw type.

Q: What is the difference between impact bits and standard screwdriver bits?

 A: Standard screwdriver bits are not designed to handle the high-torque burst forces that an impact driver produces. Under repeated impact use, standard bits wear faster and are more prone to snapping. Impact-rated bits are manufactured specifically to absorb and withstand these forces, giving longer service life in impact driver applications.

Q: Will these bits work in a standard drill or screwdriver as well as an impact driver?

 A: Yes. These bits have a standard ¼" hex shank and will fit any tool with a ¼" hex chuck, including standard drills and screwdrivers. They are rated for impact use but work equally well in non-impact tools.

Q: Are these bits compatible with the CMT Magnetic Bit Holders?

 A: Yes. The 25mm length and ¼" hex shank are compatible with both the CMT Magnetic Bit Holder (BMBHSTD) and the CMT Magnetic Quick-Release Bit Holder (BMBHQS), both available from cmt.co.uk.

Q: Do you also stock PH2 Phillips impact bits?

 A: Yes. The MAXTEC 25mm Impact Screwdriver Bits are also available in PH2 Phillips (FF110025), also in a pack of 25. Both are available from cmt.co.uk.
